This is an interesting study, though it stays mostly in the realm of materialism and the nonexistence of a “soul”.
It discounts any ideas of a lucid dream being anything more than a dream, or possibly an out of body experience.
You can
DEFINITELY tell and feel a difference between the two...especially when in the vibratory state.
And indeed, many of the personal quotes from experiencers are all reduced to “just dreams”.
For myself, I know that I left my body on more than one occasion - I was NOT just a dream.
As a critical thinker and possible experiencer yourselves - you decide.
Imho, many of the questions contained within can be answered by accepting the duality of the brain/mind.
One day I believe we will merge science with the spiritual more and when we do, many questions previously unknown will be answered.
A great read nonetheless.
Enjoy!

I. Introduction
Realization that one is dreaming brings a wonderful sense of freedom–freedom to try anything in the extended range of experience.
… The nature of lucid dream experience may range up to the mystical, whilst there seems to be an inherent resistance to anything erotic.
(McCreery, 1973: 114)
When lucid dreams endure beyond a certain point, at least for me, orgasm is almost inevitable… in fully two-thirds of my lucid dreams, I feel the flow of sexual energy; this arousal culminates in an orgasmic burst on about half of these occasions.
(Garfield, 1979: 134-35)
What can we conclude from the above quotations?
Certainly nothing regarding the nature of eroticism in the lucid dream state.
Rather, they illustrate that the experience of lucid dreaming is subject to individual variation.
This should not be surprising, since lucid dreaming, like all forms of conscious experience, is comprised of a flow of subjective events created by brain processes using input from sensory-perceptual modalities, internal algorithms or schemata and, perhaps, poorly understood neuronal activity associated with central nervous system homeostatic maintenance.
Variability in individual experience is inherent at all levels: anatomical in the form of limitations imposed by breath and sensory system development, physiological as sleep and REM sleep needs, inborn activation and damping tendencies, and psychological variation caused by recent and long-term experiences, the development of habits of interaction with the environment, and assumptions about the way the world works.
The range of subjective experiences reported to occur during dreaming appears wider and more variable than those typical of waking.
In this chapter we will focus on the nature of experience in lucid dreams.
We begin by showing that lucidity in dreams is not a discrete phenomenon, but that reflective consciousness exists in all dreams and can be measured on a continuum with “lucidity” and “non-lucidity” representing two ends of the spectrum.
The remainder of the chapter will explore the substantial individual variation in lucid dreams, illustrated with examples derived from the authors’ experiences.
The discussion will focus on two primary themes: the role played by belief systems and learning in shaping lucid dream experiences, and the role played by factors which appear to be independent of the dreamer’s beliefs and learning.
II. The Meaning of “Lucid Dreaming”
The distinction between
nonlucid and
lucid dreams represents perhaps the broadest level of variation in dream experiences presently recognized.
The contemporary notion of a lucid dream is a “dream in which one knows one is dreaming” (Green, 1968).
This is in contrast to
the nonlucid dream, in which dreamers are not aware of being in the dream state.
Some dream theorists treat the lucid/nonlucid distinction in a way we consider too rigid, arguing these are two completely distinct types of phenomena (Hobson, 1988, 1994; Tart, 1984; Tholey, 1988).
In our view, the distinction between
lucid and
nonlucid dreams is not as clear-cut as the definition suggests and fails to do justice to the subtlety of the actual experience.
We feel the contemporary distinction has misplaced focus away from what we consider the essential variations in dream cognition underlying dream lucidity.
We have recently developed a psychological model that we believe captures the experiential essence of the differences between lucid and nonlucid dreams (DeGracia and LaBerge, 1998).
In brief, our model hinges on the relationship of the waking self and the identity of the dreamer, and addresses the question: at what psychological levels do changes in self-awareness in the dream state occur that correspond to the onset of dream lucidity?
Or stated somewhat differently, what exactly is dream lucidity?
Our basis for answering this question involved a systematic comparison of waking, lucid and nonlucid dreaming within the framework of the
Global Workspace (
GW) model of consciousness developed by
Bernard Baars (1988).
Recognizing that dreams in general are an expression of consciousness during sleep, the critical feature of
Baars’s GW model we used was his formulation that conscious processes are molded and framed by unconscious processes.
Baars formulates unconscious processes as contexts.
Contexts are operationally defined as “a system (or set of systems) that constrains conscious contents without itself being conscious” (Baars, 1988: 372).
Accordingly, we compared the unconscious contextual structures underlying waking, nonlucid and lucid dream consciousness.
A. Waking
Baars’ GW model provides a model of waking consciousness.
The GW model posits that waking consciousness is framed by a nested hierarchy of unconscious elements which Baars terms a context hierarchy.
The context hierarchy is a relatively stable global construct that transforms through time as a function of learning and experience.
The context hierarchy of the waking personality is composed of many relatively distinct contexts which correspond to, or are a computational way to model, the sensory, perceptual, attentional, mnemonic, cognitive, metacognitive, goal and effector operations carried out unconsciously by the nervous system, but which in turn condition conscious experience.
Contexts can be relatively more innate (such as the topographic organization of conscious perceptions) or relatively more learned (such as language and culture).
A context strongly dependent on learning can involve situation-dependent forms of cognition, in which the context remains latent until external circumstances dictate its full expression.
An example of a situation-dependent context would be the knowledge and skills associated with piano playing.
The full expression of a “piano playing context” is situationally dependent on the presence of an actual piano.
When confronted with a piano, the “piano playing context” expresses itself as a nested hierarchy of effectors: the desire (or goal) to play triggers the necessary declarative knowledge (of notes and music, etc) which in turn triggers the necessary motor effectors (eye motions for reading music, hand motions for striking keys) resulting in the act of playing the piano.
According to Baars, context formation initially requires conscious participation.
But, once established, contexts are unconscious factors framing conscious experience.
Many such contexts accumulate within the waking personality as a function of learning and life experiences, and mold and frame the conscious aspects of waking.
B. Nonlucid Dreams
During
nonlucid dreams, the consciousness of the dreamer is similarly constrained by unconscious contextual elements.
These elements combine to form relatively transient global contexts that last only for a dream’s duration, or possibly through a series of sequential dreams.
The transience of global contextual structures in dreams contrasts to the relatively stable context hierarchy framing waking consciousness.
One factor contributing to the transient quality of dream contexts involves the dreamer operating “in the moment” in response to the dream context with no conscious memory of precedents or antecedents to the events occurring in the dream.
The
unconscious global context framing nonlucid dream consciousness may or may not use elements from the waking context hierarchy.
Typically, dream contextual elements related to explicit memories do not necessarily correlate to elements of the waking personality, while contexts related to non-explicit memories do.
For example, the dreamer’s sense of identity (a declarative context) may be significantly different from the waking sense of identity (LaBerge, 1985). Likewise, the conceptual situation of the nonlucid dream (e.g. the “dream plot”) may have little to do with the episodic experiences of the waking personality.
This “incongruency of contexts” between waking and nonlucid dreaming perhaps contributes to the view of some theorists that the nonlucid dream state is akin to madness (Hobson, 1994).
However, contexts defining non-explicit behaviors, when expressed in nonlucid dreams, are closely similar to waking.
Such non-explicit behaviors include, for example, conscious perceptual representation (DeGracia and LaBerge, 1998), speech production (Salzarulo and Cipolli, 1974), or metacognitive monitoring (Kahan and LaBerge, 1994).
The carry over of waking habits of metacognitive monitoring has a particular significance in nonlucid dreams.
We typically do not metacognitively monitor our state of consciousness when awake.
The general set of expectancies guiding our ordinary waking experience also governs our ordinary dream state.
Since we tacitly assume, in both cases, that we are awake, our cognition during dreaming is distorted to fit the assumption that we are awake.
When bizarre dream events occur, as they frequently do during REM sleep, they are simply assimilated into the contextual structure of the dream in a consistent fashion (DeGracia and LaBerge, 1998).
Again, some theorists have used this assimilation by the dreamer of unusual dream events as evidence that dreaming cognition is akin to madness.
From our view, however, we are simply observing the adoption of the waking self’s habitual form of metacognitive monitoring by the dreamer.
Importantly, the contextual structures and conscious experiences of nonlucid dreams tend not to contribute episodic memories to the waking personality; a condition recognized as dream amnesia (Hobson, 1988).
Although it is common to recall fragments of dreams upon awakening, it is likely that the great majority of our nightly dreams are not remembered at all (Diamond, 1963).
For most individuals there is only a piecemeal conscious recollection of dream experiences.
However, as stated above, the nonlucid dreamer can access both explicit and non-explicit memories of waking experience.
Nonlucid dreaming therefore tends to be a one-way street with respect to memory transfer between states: from waking to dreaming, but not the reverse.
The result of this relatively one-sided transfer of memories between states means that elements of the waking personality can contribute to the identity of the dreamer as building blocks in the global (albeit temporary) contextual structure of the dream.
But, dreams rarely contribute to the consciously accessible memories of the waking personality.
Because of the transient nature of the global contexts in nonlucid dreams, we suggest nonlucid dreams may function, among other things, to recombine unconscious elements within consciousness on a temporary basis.
We call this process “mental recombination” (cf. Hunt, 1989) by analogy with genetic recombination.
From the viewpoint of biocomputation, mental recombination likely contributes to maintaining an optimal information processing flexibility in brain neuronal networks.
This notion is practically identical with Greenberg and Pearlman’s (1974) conclusion that the evolutionary development of the dream state “has made possible the increasingly flexible use of information in the mammalian family”.
The notion of dreaming as mental recombination is also consistent with the role of REM sleep in learning and assimilation of new knowledge (reviewed in LaBerge, 1985).
C. Lucid Dreams
Lucid dream consciousness, like
waking and
nonlucid dreams, is also framed by unconscious contextual elements.
To understand the contextual structure of lucid dreams, we must look at the role played by consciously accessible memory across lucid dreams and waking.
Lucid dreamers are able to freely recall details of waking life, to a greater or lesser extent, while within a lucid dream (LaBerge, 1985).
Just as important, lucid dreams are remembered after awakening with a much higher frequency than nonlucid dreams, probably due to the presence of a mental set to remember in lucid dreams.
Although it would be difficult to empirically ascertain, the anecdotal evidence suggests that at least some lucid dreamers remember their lucid dreams during waking at least as well as their waking experiences (LaBerge, 1985).
In other words, lucid dreams contribute to the episodic memories of the waking personality.
Therefore, in contrast to nonlucid dreams, there is a two-way transfer of consciously accessible memory between waking and lucid dream experiences.
Thus, there is a relative continuity of consciously accessible memory linking lucid dreams and waking experience.
With repeated experiences of lucid dreaming, the associated memories of these experiences contribute to the formation of a stable and cumulative contextual structure in the mind of the waking self.
This stable contextual structure we call the lucid dream context.
The lucid dream context serves two complementary roles:
(1) it serves as the global contextual structure framing lucid dream consciousness providing both precedent and antecedent structure to lucid dreams, and (2) it forms a situationally-dependent context within the waking personality. Regarding this latter point, lucid dreaming is a learnable skill (Moffitt, Hoffmann, et al, 1988; LaBerge, 1980, 1985; LaBerge & Rheingold, 1990).
The full expression of this skill is dependent upon its occurrence during sleep, and is in this sense a form of situational cognition.
The skill, however, belongs to the waking personality and shares features with other learned skills, particularly that it can be improved upon by learning and practice (LaBerge, 1980).
Thus, our distinction between lucid and nonlucid dreams is based on the contextual structure underlying dream consciousness: nonlucid dreams can be characterized by the formation of transient global contexts different from dream to dream, but lucid dreams are characterized by the presence of a distinct and persistent context, the lucid dream context.
This lucid dream context belongs to both the waking personality and the lucid dreamer identity, serving as a bridge between them, and will continue to frame all future lucid dreams.
The lucid dream context is susceptible to modification by learning and experience acquired in either the waking or lucid dream states.
There appear to be at least three essential components to the lucid dream context, each operating at a specific psychological level:
(1) a “reference to state” operating as a metacognitive context,
(2) a semantic contextual framework operating at the level of declarative knowledge, expectation and belief, and
(3) a goal-option framework operating at the level of effector action.
1. The Reference to State
When a lucid dreamer thinks “I am dreaming” there are at least two levels of cognitive activity at work in this thought: a direct experiential realization of, and self-reflection on, ones condition (”I am...”), and an interpretation of the nature of that condition (”…dreaming”).
The former is a metacognitive act, the latter a semantic interpretation.
The notion of “reference to state” indicates the metacognitive component of the lucid dream context.
The reference of subjects to their state of being is not merely declarative knowledge, it is a direct apprehension of their immediate experience. Metacognition is not unique to lucid dreams but also occurs in nonlucid dreams (Kahan and LaBerge, 1994).
However, in nonlucid dreams, “reflection during dreaming involves an awareness of conditions within the dream” (ibid., p. 250).
That is to say, reflection on events in nonlucid dreams is confined to the contextual scope of the nonlucid dream (typically limited by the absence of the habit of metacognitively checking one’s state).
Metacognition during lucid dreams is not confined to events occurring in the dream, but references, either explicitly or implicitly, waking experience as well (DeGracia and LaBerge, 1998).
The reference to state in a lucid dream is framed by access to memories of waking experience, allowing a contrast between one’s current situation and the knowledge of waking life.
This contrast provides the contextual structure for the metacognitive recognition that the current experience is not a normal waking experience.
Hence, lucidity in the context of dreaming, implies metacognition framed by consciously accessible memories of waking experience.
2. The Semantic Framework
Individuals who experience lucid dreaming develop a framework of knowledge by which to conceptualize and give meaning to their experiences.
These semantic frameworks affect the consciousness of lucid dreamers in a contextual fashion by providing assumptions, expectations and beliefs upon which the lucid dreamers interpret their experiences and acts.
Because there is a large diversity of perceptual experience in lucid dreams (to be outlined below), an equally wide variety of semantic frameworks have developed to give meaning to these experiences.
The knowledge framework used by a given individual does not require that the experiences be conceptualized by that individual as “a lucid dream”.
The semantic framework itself does not even have to be true.
How lucid dreamers conceptualize their “non-waking experience” is a function of their general knowledge.
Alternative modes of conceptualizing the lucid dream experience include the notions that one is undergoing an “out of body experience” (OBE) or an “astral projection” (reviewed in DeGracia, 1997).
The forms taken by one’s reference to state depend on one’s semantic framework.
So, the semantic component of the statement “I am dreaming” reflects a knowledge structure conceptualizing the experience as a form of dreaming.
A reference to state can just as easily take the forms “I am having an OBE” or “I am having an astral projection”.
As one of us stated previously: “…lucid dreams and OBEs [and we will add here, astral projections] are necessarily distinguished by only one essential feature: how the person interprets the experience at the time” (LaBerge, 1985, p. 234)
In other words, these are not phenomenologically distinct categories of experience but are alternative conceptualizations of the intrinsic variety present in lucid dream experiences.
Because dream experience is not constrained by sensory input or other limits of waking experience (such as the law of gravity, for example) beliefs and expectations play a key role in determining the form of and behavior occurring within a lucid dream.
As we stated in the Introduction, we are interested in ascertaining which features of lucid dream variability are belief-dependent and which are not.
By “belief-dependent” we are referring precisely to the role played by a semantic framework in conditioning an individual’s lucid dream experiences.
The semantic framework, because it is a declarative framework of knowledge, is susceptible to modification by learning and experience, and therefore is a crucial dynamic element in an individual’s lucid dream context.
3. The Goal-Options Context
Lucid dreaming includes a set of intentional actions that, taken as a whole, we call a goal-options context.
As the semantic framework is the declarative component of the lucid dream context, the goal-options context includes the procedural aspects of lucid dreaming related to effector actions.
A lucid dreamer’s goal-option context includes both lucid dream initiation techniques and the range of behaviors expressed in an individual’s lucid dreams. Examples of characteristic goal-option behaviors include making voluntary choices in lucid dreams, making a habit of metacognitively checking one’s state of consciousness, and making a habit of remembering lucid dream experiences.
The goal-option context is also a dynamic element of the lucid dream context which undergoes refinement concomitant with the accumulation of direct experience in the lucid dream state.
The semantic framework has a direct effect on the goal-options available to the lucid dreamer by limiting what the dreamer believes is and is not possible to do in the lucid dream state.
D. The Relationship Between Nonlucid and Lucid Dreams
Let us summarize the discussion thus far.
Dream lucidity involves specific unconscious contextual structures operating at metacognitive, semantic and effector levels that frame the consciousness of the lucid dreamer: together these form a lucid dream context.
A lucid dream context develops from a two-way, consciously accessible memory transfer between the lucid dreamer and waking self, represents learned skills, and is a stable facet of the waking personality which grows with experience.
In contrast, nonlucid dreams are characterized by the transient formation of dream contexts which draw, to a variable extent, on elements of the waking personality, and do not contribute substantially to the consciously accessible memory structure of the waking personality.
Although this model appears to provide a clear-cut distinction between lucid and nonlucid dreams, it is not the main intention of this model to rigidly distinguish these experiences.
We stated above our dissatisfaction with the current dichotomous notions of nonlucid and lucid dreams in this regard.
This dissatisfaction derives from the inability of contemporary notions to adequately capture the lucid dreamer’s experience, which can display subtle variations in cognition that are difficult to conceptualize.
These variations seem to span the distinction between lucidity and non-lucidity as presented above so that our model is really intended to provide a basis for conceptualizing the subtle array of differences present in lucid dream experiences.
Thus, the final step in our model is to develop how lucid and nonlucid forms of cognition can interact with one another.
To do so, we must turn again to notions introduced by Baars in the GW system.
Baars defines the processes of cooperation and competition; these are mechanisms by which contexts interact.
Cooperation refers to how contextual elements can form symbiotic linkages and mutually support each other in framing conscious processes.
For example, the association of the metacognitive reference to state, semantic framework and goal-options context within the lucid dream context is an example of the cooperation of contextual elements.
Competition is the opposite process whereby contextual elements displace one another in their effects on conscious processes.
A waking example of competition can be found in the Stroop test, where one reads colored words of the names of colors flashed briefly on a monitor. People tend to mistakenly say the color of the word, instead of reading the word itself.
Here, unconscious color recognition processes compete with unconscious word recognition for control of the contents of consciousness.
We showed that cooperation and competition of contextual elements can be observed in both nonlucid and lucid dreams (DeGracia and LaBerge, 1998). We also showed that the tendency of nonlucid dreams to form transient global contexts is present during lucid dreams.
Characters and situations encountered unintentionally in lucid dreams can serve as factors around which may nucleate a nonlucid dream context.
These factors can compete with the lucid dream context for access to the dreamer’s intentions.
If the lucid dreamer does not make a conscious effort to maintain the lucid dream context, it is possible for these distractions to absorb the attention of the lucid dreamer and draw the dreamer into a situation that unfolds independent of the dreamer’s volition.
At the extreme, a newly generated dream context can displace the lucid dream context resulting in a loss of lucidity and the transformation of the lucid dream into a nonlucid dream.
In practice, however, subtler forms of competition will allow the lucid dream context to co-exist with competing dream elements that are not contained in the lucid dream context, resulting in modifications of the cognition of the lucid dreamer which affect memory access, thinking and behavior.
In such situations, the dreamer appears to phase in and out of lucidity to various degrees.
Thus, because of competitive processes, the degree of lucidity can itself vary within a single lucid dream.
These notions will form part of our basis for discussing variations in lucid dream cognition in following sections.
III. Variations in Lucid Dream Experiences
Having presented a way of looking at the distinction between lucid and nonlucid dreams, we will now turn our attention to outlining the degree of variety that exists in lucid dream experiences.
Because lucid dream experiences tend to be remembered nearly as well as waking experiences, and because lucid dreams are cumulative experiences, lucid dream reports can provide highly detailed and descriptive accounts of lucid dream phenomenology.
We will draw on such reports below to illustrate the range of variation in lucid dreams.
Our survey of lucid dream variations will parallel the general temporal course of lucid dreams, discussing in turn, lucidity initiation, variations in perception, emotion, cognition and action within lucid dreams, and finally, the termination of lucid dreams.
A. Variations in Lucid Dream Initiation
Since the lucid dream context bridges the waking and dream states, logic suggests that lucid dreams could be initiated either from the nonlucid dream state (a dream-initiated lucid dream, or DILD) or from the waking state (a wake-initiated lucid dream, or WILD) (LaBerge, 1980).
Because transitions directly from the waking state to the REM sleep state are very rare, one would expect WILDs to occur with a lower frequency than DILDs–just what the data shows.
1. Dream-Initiated Lucid Dreams
More than 80% of lucid dreams are initiated when a nonlucid dream transforms into a lucid dream (LaBerge, Nagel, Taylor, Dement, & Zarcone, 1981). This process involves the lucid dream context displacing the current nonlucid dream context.
The form of this displacement is dependent upon the individual’s specific training in lucidity induction techniques and degree of lucid dreaming experience.
For
inexperienced lucid dreamers, lucidity is perhaps most likely to arise from a nightmare or anxiety dream.
LaBerge (1985) argues that there is an evolutionary-biological basis for anxiety stimulating reflective consciousness.
Not all novice lucid dreamers experience anxiety-triggered lucidity; specifically, for example, DLD reports none, while SLB reports his percentage of anxiety-triggered lucid dreams recognized in years 1-3 respectively were 36%, 19%, and 5.
The decrease in proportion (and frequency) of anxiety-initiated lucid dreams with time was probably due to the psychotherapeutic techniques SLB was practicing (LaBerge, 1985; see also Tholey, 1988) as the following example illustrates:
(SLB106)
“I was in the middle of a riot in a classroom; a furious mob was raging about, throwing chairs and fighting with each other. A huge repulsive barbarian with a pock-marked face, the Goliath among them, had me locked in an iron grip from which I was futilely trying to free myself. At this point, I recognized that I was dreaming, and remembering what I had learned from handling similar situations previously, I immediately gave up my struggle … and tried to feel loving as I stood face to face with my ogre.
At first, I failed utterly, feeling only repulsion and disgust for the ogre. He was simply too ugly to love: thus spoke my visceral reactions. But I tried to ignore the image and seek love within my own heart. Finding it, I looked my ogre in the eyes, trusting my intuition to supply the right things to say. Beautiful words of acceptance flowed out of me, and as they did, he melted into me. As for the riot, it had vanished without a trace; the dream was over and I awoke, feeling wonderfully calm.”
Other intense emotions such as embarrassment or delight can also initiate lucidity.
Such lucid dreams are typically spontaneous and brief, and lucidity onset is quickly followed by awakening.
Survey data suggest that most people have experienced a nominally lucid dream at least once in their lifetime (Snyder and Gackenbach, 1988).
A spontaneously experienced lucid dream can serve as a nucleation event for the development of a lucid dream context, if there is follow-through on the part of the individual to cultivate these experiences.
A number of methods exist for the individual to intentionally cultivate the onset of lucidity from within nonlucid dreams (LaBerge, 1981, 1985; LaBerge and Rheingold, 1990; Rogo, 1983).
The learning of these methods occurs during waking and adds to both the semantic and goal-option components of an individual’s lucid dream context. The essence of methods to initiate lucidity during nonlucid dreams is to condition dreamers to recognize that they are dreaming through some form of state testing (also called “reality testing”).
Some approaches to state testing are:
1. Anomaly recognition - Here dreamers condition themselves to use the recognition of bizarre dream events as a cue for lucidity onset.
This approach is not limited to observing events in the dream but can be based on self-observation as well, so that, if they perceive their behavior as unusual (not typical of waking) this may induce lucidity.
(SLB351) “I’m walking through a field that is fantastically animated with extravagant life: Magic Mushrooms (Psilocybe cubensis ) popping up everywhere and growing to gigantic proportions. I realize the fantasy element of this scene: I must be dreaming. I do two all up eye movement signals, but this causes the dream to begin to fade. I try to press the micro-switch, and I seem to have succeeded, but it feels like I’m already awake...”
The anomalies that serve as lucidity cues, or “dreamsigns” (LaBerge & Rheingold, 1989) can be very subtle indeed as the following account from von Moers-Messmer (1938) illustrates:
From the top of a rather low and unfamiliar hill, I look out across a wide plain towards the horizon. It crosses my mind that I have no idea what time of year it is. I check the sun's position. It appears almost straight above me with its usual brightness. This is surprising, as it occurs to me that it is now autumn, and the sun was much lower only a short time ago. I think it over: the sun is now perpendicular to the equator, so here it has to appear at an angle of approximately 45 degrees. So if my shadow does not correspond to my own height, I must be dreaming. I examine it: it is about 30 centimeters long. It takes considerable effort for me to believe this almost blindingly bright landscape and all of its features to be only an illusion. [Translation from LaBerge, 1985, pp. 38-39.]
2. Programmed behaviors - Here dreamers condition themselves to perform an act that will tend to produce distinguishable results when performed during either waking or dreaming.
For example, attempting to fly in a dream will tend to lead to the experience of flying; if the individual actually “lifts off” then this is a strong indication that the experience is a dream (as in the following example).
Another behavior that can result in lucidity initiation is attempting to read and reread text; if the text changes, then this is used as a lucidity cue.
This approach can be simplified to the point of simply looking at one’s hands as a cue for lucidity onset.
(SLB1032)
“At a movie theatre, I am running down a flight of stairs, skipping more and more steps, until I notice that I seem to be able to skip as many as I like! Wait a minute! That makes this a dream. But it doesn’t seem at all like it. So I step into the air to convince myself. It is indeed! As I float upward close to the wall, the scene begins to fade. I decide to test rubbing hands together instead of spinning. I vividly feel the sensation and then also the wall at my back. I keep rubbing for perhaps 15 seconds, and then I feel a closet door, which I open. At first the closet contains only vague images, but they finally become vivid. I am now in a bedroom. L is on the bed, “talking in her sleep.” She says something unintelligible. I ask her to repeat it: She says “Wisdom is being given out …mumble, mumble.” While wondering what she means, the dream fades and I awaken.”
3. Déjà rêvé - Lucidity can sometimes be initiated when lucid dreamers have an apparent or actual recognition that they have had a similar dream before as in the following example:
(SLB31)
“I am walking with my friend, M, when I recognize that we are in a place I have dreamed of before–‘The Museum of Uninvented Inventions’–and that this therefore, is a dream. I reflect how the real M. would like to have lucid dreams, knowing quite explicitly that this is ‘M’, a dream figure. Nevertheless, I suggest to him that even though he is only a dream character, perhaps he could realize that he is dreaming. Maybe he does, for I wake up.”
With increasing experience, DILD techniques become habitual.
After a certain degree of experience, the individuals may simply recognize that they are dreaming without any apparent state testing or lucidity onset cue.
Frequently dreamers question their state and decide they are awake and not dreaming.
A dream in which the dreamer has at one point raised this question without arriving at the correct conclusion is commonly termed “pre-lucid” (Green, 1968).
Pre-lucid dreams can be interpreted as a failed attempt by the lucid dream context to gain full access to framing dream consciousness.
2. Wake-Initiated Lucid Dreams
It is possible to maintain continuous reflective consciousness while falling asleep and hence to enter a lucid dream directly from the waking state.
As with DILDs, this form of lucid dream initiation is a skill that improves with motivation and practice.
Its cultivation has been described by Tibetan yogis, and several modern sources (LaBerge 1985; LaBerge and Rheingold 1990; Ouspensky, 1960; Rogo 1983).
WILDs are most likely to occur after awakening in the morning or during afternoon naps (LaBerge, 1980).
While falling asleep, the subject’s mind is kept focused and lucid through the transition from waking to dreaming.
Experiences of visual and auditory hypnagogic imagery are common during this transition.
Unusual somesthetic imagery may also occur; subjects may feel themselves “float” or “sink out of their body”.
There may (e.g. SLB561) or may not (e.g. SLB37) be a momentary break in subjects’ consciousness.
Then the subjects will find themselves fully in a dream scene and lucid.
Once in the dream-state, the lucid dream continues exactly like those initiated directly from the dream state.
Skarekrow here...this is describing having a possible out of body experience that the author(s) have dismissed as only created by the mind and not in actuality what it appears to be to the one having the experience.
In other words - people who have little to no personal experience, and those who cannot muster enough faith to believe we have a soul are giving their “scientific” explanation when they have no idea themselves how, why, or what would make the experience so different than an actual “lucid dream” where you become aware you are dreaming.
Once again...decide for yourself...I for one, know what I experienced and continue to experience occasionally.
I for one do not believe I was dreaming any more than you believe you are right now reading this.
Some examples from the authors’ personal experiences illustrate the fascination of this transition:
(DDG55)
“I went back and laid on my bed hoping to project some more. I laid there and hypnagogic images came and went: city scenes, people sitting at a bar, a friend sitting on a stool behind an open door with a beautiful girl standing next to him. I could feel myself sinking deeper and deeper. Finally, I felt myself sink very deep and simultaneously my visual field locked into a stable scene and I felt a strong wind blowing over me. I could hear loud “whooshing” and wind sounds. Next I knew, the “wind” grabbed me and was pulling me along. It seemed to be pulling me forward but what I saw was me passing through fuzzy but identifiable frames of my bedroom.”
(DDG48)
“I woke from sleep. Had fleeting glimpses of my dream memories, then they were gone. I shut my eyes and could see hypnagogic images. A few scenes formed and faded but I don’t recall what they were. The scene of a street formed vividly in front of my closed eyes. There was a river off to my left, 50-100 yards from the road. On the left seemed to be a construction site. There were buildings on my right. I was trying to observe details and I felt my foot step forward! This surprised me! Next thing I knew, I was walking along the street.”
(SLB561)
“I have just awakened from a dream in the sleep lab and am worrying about how the night is almost over and I still haven’t succeeded in having a lucid dream. Suddenly, I find myself flying hundreds of feet above a field of wildflowers: I realize at once, with great excitement, that this is a dream and carry out the pre-planned protocol, making an eye-movement signal and singing ‘Row, row, row your boat/ Gently down the stream/ Merrily, merrily, merrily/ Life is but a dream!’ Then I make another signal and estimate 10 seconds by counting ‘One thousand-one, ... one thousand-ten’ and signal again. When I finish this sequence, I am overjoyed and do a virtual cartwheel in the air. After a few seconds, the dream begins to fade….”
(SLB37)
“I was lying awake in bed late in the morning listening to the sound of running water in the adjoining bathroom. Presently, an image of the ocean appeared, dim at first like my usual waking imagery. But its vividness rapidly increased while, at the same time, the sound level of the running water decreased; the intensity of the internal image and external sound seemed to alter inversely (as if one changed a stereo balance control from one channel to the other). In a few seconds, I found myself at the seashore standing between my mother and a girl who seemed somehow familiar. I could no longer hear the sound of the bath water, but only the roar of the dream sea….”
Differences in styles of lucid dreaming give rise to individual differences in DILD and WILD frequency.
Although quantification of such differences has not been attempted in a large sample of lucid dreamers, to illustrate such stylistic differences, a comparison of lucid dream initiation frequencies of the authors is here presented.
DDG has 114 recorded lucid dreams of which 43% were WILDs and 56% were DILDs.
In contrast, only 8% of SLB’s dissertation sample of 388 recorded lucid dreams were WILDs, a significantly lower proportion.
3. Ambiguities in Lucidity Induction
With increasing experience, some facets of lucid dreaming become habitual, making the classification of dream lucidity more ambiguous.
Consider the following example:
(DDG74)
“My (nonlucid) dream involved me, X and a bunch of other people. We were all roommates in a big house. I was unaware that I was dreaming. There was a party going on or something. We were down in the basement hanging out. However, at some point in the dream I looked at X and told him I’d be back in a little bit because I was going to go up to my room and try to project! I went up to my bedroom in this dream house. Again, at this point I thought everything was normal and had no idea I was dreaming. I laid down on my bed and started concentrating to leave just exactly like I always do on the physical plane….[text omitted of a 1400 word lucid dream report]
…I decided I was done for the time being, so I got up out of bed. I was still in the dream house and still unaware that I was dreaming. I went looking for some paper to record my experience. I ended up going back into the basement where everyone was still hanging out. X was there and the others and I told them all about the projection I had just had. Meanwhile, I’m getting very concerned that I can’t find any paper. Then I woke up for real. For a moment I was totally disoriented.”
In this example, DDG, in the midst of a nonlucid dream, performs his habitual techniques for achieving a WILD. He then experienced what was, for all practical purposes, a typical lucid dream. Following this, he “awakes” in the exact same nonlucid dream setting and seeks paper to record his lucid dream, which is also a habitual behavior. Shortly thereafter, DDG truly wakes up in a momentarily disoriented state.
How is one to classify such an experience?
What we see here is a lucid dream nested perfectly inside of a nonlucid dream.
One could argue that DDG merely dreamt that he was lucid dreaming, but this clarifies nothing.
The characteristics of the lucid dream (the omitted text) were identical in general features to all of his other lucid dreams.
What we believe this particular sequence represents is the cooperation between the global nonlucid dream context and DDG’s lucid dream context.
In this particular instance, the global nonlucid dream context provided perfectly for the full expression of the lucid dream context because the subject dreamt all of the requisite details needed for activation of his lucid dream context.
After completion of the lucid dream, the lucid dream context returned control of access to the dreamer’s consciousness to the previous nonlucid dream context.
This kind of situation could only result because the subject possessed a well-defined lucid dream context that could clearly demarcate itself from the global nonlucid dream context.
This is an extreme example of the mixing of nonlucid and lucid dream elements.
However, it is not uncharacteristic of the kind of subtleties and ambiguities encountered when attempting to characterize dream consciousness and what does and does not constitute dream lucidity.
A related issue is the characterization of intentionality in lucidity induction.
It is not always easy to draw a clear distinction between a lucid dream that is “spontaneous” and one that is “deliberately” induced.
In fact, the characterization of such factors is critically dependent upon the subject’s degree of experience, and the relative maturity of the lucid dream context.
As the lucid dream context matures, and hence, becomes more habitual, the likelihood of unintended lucid dreams increases and the ambiguity of what constitutes dream lucidity also increases.
WILDs are typically intentional by nature.
However, it is possible, for example, for an experienced lucid dreamer to lie down and nap with the intention to merely rest, and have an unintended WILD.
In the case of DILDs, the issue of intention becomes even more ambiguous because the experienced subject may simply come to learn to recognize that he or she is dreaming, with no cause other than sheer familiarity with the state; in such a case, there may be no explicit onset of lucidity (e.g. no reality testing, no statement “I am dreaming”).
Alternatively, experienced lucid dreamers may have a nonlucid dream in which they access elements of their lucid dream context incompletely and never achieve full lucidity.
These types of considerations are important because they indicate that the subject’s degree of experience can profoundly affect how dream lucidity manifests itself, and clearly indicate that lucidity induction is not homogeneous across subjects.
What constitutes dream lucidity may be more subtle and ambiguous to identify for experienced subjects who have programmed aspects of lucidity induction and manifestation to be habitual.
B. Perceptual Variations in Lucid Dreams
The examples listed above begin to illustrate the diversity of perceptions that can occur in lucid dreams.
By “perception” we are referring to the hallucinated sensory modalities characteristic of dream consciousness.
Because afferent input from peripheral senses is attenuated during dreaming (LaBerge, 1985), it should be understood that the use of the term “perception” in the following discussion refers to the hallucinated analogs of the sensory modalities.
Dreams are, in general, highly perceptual experiences expressing all the dream analogs of waking sensory modalities.
Dream perceptions are typically characterized as “bizarre” (Hobson, 1988).
Examples of perceptual bizarreness in dreams may include dream characters or environments transforming abruptly (discontinuities), or the perception of physically impossible scenes and events.
Perceptual bizarreness occurs in lucid dreams just as it occurs in nonlucid dreams (Gackenbach, 1988).
However, bizarreness in perception is often recognized as such by lucid dreamers, and can be described by them in vivid detail, providing us with a clear window into the perceptual qualities of lucid dreams.
To understand the perceptual diversity of lucid dreams we need to introduce the notion of perceptual environment.
This is the complete hallucinated sensorium of the dreamer including all the sensory modalities: vision, audition, somatosensation, gustation, olfaction and the submodalities therein.
These hallucinated sensory perceptions combine to form the dreamer’s body image (if present), and the allocentric space perceived by the dreamer.
The dreamer can be either immersed within the dream environment or observing it from without.
Again...I disagree with their term - “hallucination”.
For both authors, our lucid dreams are associated with immersion in the perceptual environment, which seems to hold true in general; reports of lucid dreamers as pure observers are rare (LaBerge, 1985).
The vividness and richness of the perceptual environment ranges from the “minimal” in which most or all sensory qualities are absent or greatly attenuated, through the “typical” much like everyday experience, to the “surreal” in which the environment is vibrantly, psychedelically alive with fantastic, extravagant detail.
1. Typical Perceptual Environments
A “typical” perceptual environment is experienced as immersion within or observation of a rich sensory environment containing all sensory modalities. Typical perceptual environments are characteristic of both nonlucid and lucid dreams.
These environments generally contain the same elements that waking environments do such as landscapes, city streets, trees, buildings, driving in cars, etc., and are readily comprehensible by the dreamer, although bizarreness is frequent.
Within lucid dreams, typical perceptual environments display a large variety of perceptual qualities.
In some the scene is dimly lit or vaguely delineated; others overwhelm the lucid dreamer with their intense beauty and extravagant detail.
Some seem, indeed, “more real than real”.
In general, the average lucid dream is more perceptually vivid than the average nonlucid dream.
This conclusion is supported by relatively intense brain activation during lucid dreaming which may correlate with increased perceptual vividness (LaBerge, 1981).
2. Surreal Perceptual Environments
A surreal perceptual environment is characterized by the presence of at least some sensory modalities displaying rich perceptual content.
However, surreal environments have no counterpart in normal waking experience; they are often abstract spaces of color, shape, and motion within which the dreamer is immersed.
These environments are abstract, and typically are not comprehendible by the dreamer.
Surreal perceptual environments occur very rarely in nonlucid dreams (Hall and Van de Castle, 1966), although Hunt (1989) has discussed them in the context of activated dreams.
A clear distinction should be drawn between surreal environments and bizarreness perceived in typical environments.
Some forms of hypnagogic imagery and psychedelic drug-induced hallucinations (e.g. described in Mavromatis, 1987, and Aaronson and Osmond, 1970, respectively) resemble surreal perceptual environments, but in lucid dreams, there is a definite sense of somatic immersion in the environment.
The following are examples of surreal perceptual environments; the lucid dreamer’s lack of comprehension of his perceptions are apparent:
(DDG75)
“But I managed to turn around and what I saw was unbelievable and utterly amazing. I don’t even really know how to describe it! When, after great effort, I turned myself around, I was no longer seeing the forest. Instead I was looking onto this unbelievable colored field and there were three spheres ahead of me and they had something that looked like butterflies dancing in each of them. But they were not butterflies, though they looked a little like them. Whatever they were, there was one each inside of the three spheres and these “butterflies” were spinning and rotating within the sphere and constantly changing color. The way they changed color was strange, it was as if colors were welling into them from somewhere I could not see, like a liquid, and flowing around inside of these butterfly creatures. I was both awed and confused; confused that the forest was gone, and confused at what I was looking at, awed because whatever I was looking at was very, very beautiful.”
(DDG70)
“I got the idea to shut my eyes, spin around rapidly, and pretend that I was shrinking. When I did this and opened my eyes up I was quite surprised to see that I was actually somewhere else! And what I saw when I opened my eyes was amazing. I was in the midst of a spectacular panorama of swirling activity and spiraling colors. The scene was staggering in its complexity. I was floating amongst the images, floating surrounded by these moving color patterns. I remember that I was amazed, but baffled, and didn’t understand in the least what I was looking at, other than that it was very beautiful and moving around too much to make out any definite structure.”
What these surreal perceptions represent is currently unknown.
It is intriguing, however, to speculate that lucid dreamers perceiving such imagery may be in fact perceiving the lower level neurological processes that underlie normal conscious sensory perceptions, as has been suggested for LSD-induced hallucinations (Mavromatis, 1983).
Again...since they have no good explanation they dismiss such things as LSD type hallucinations...that’s quite a conclusion to jump to when you have no working model representing it or otherwise.
3. Minimal Perceptual Environments
Minimal perceptual environments are characterized by immersion in an environment containing a minimum of sensory perception.
Again, these appear to occur frequently in lucid dreams, but rarely in nonlucid dreams.
This is a relatively neglected area in the literature with the exception of Gillespie (1988), who has experimented extensively with deliberately eliminating sensory content from his lucid dreams.
It is not uncommon for lucid dreamers to involuntarily “fade” from a lucid dream to the waking state with no break in consciousness (LaBerge, DeGracia, et al., 1998).
Prior to and during the fading process, lucid dreamers perceive their sensorium as “unstable”.
In general, lucid dreamers learn to perceive their sensorium as more or less stable; this is a perception with no counterpart during waking.
When a lucid dream is “stable”, all perceptions of the dream environment appear normal.
When a lucid dream is “unstable”, there may be a “blinking on and off” of the visual field, as if one is phasing in and out of blindness.
The visual field may also become cartoon-like or pale in color.
Somatic sensations may feel as if they are fading in and out.
Although the basis of this fading process is not currently understood, techniques exist to stabilize one’s sensorium in the event that it is perceived to be fading (LaBerge, DeGracia, et al., 1998).
The degree to which lucid dreamers experience instability events seems to be quite variable both between and within subjects.
We know of no waking counterparts for the perception and sensations associated with fading and stability.
These are wholly experienced and learned in the lucid dream state.
Even in nonlucid dreams the experience of fading appears confined to the transition to waking.
However, in lucid dreams, variations in one’s “stability” can occur at any time during a lucid dream, for a greater or lesser duration.
Minimal perceptual environments are related to perceptions of fading and stability.
Some individual lucid dreamers do not awaken when they experience a complete loss of stability and fade from their lucid dreams.
Instead they find themselves in minimal perceptual environments.
Minimal perceptual environments are characterized by a loss of the rich sensory modalities typical of dreaming; such experiences may be perceived by the lucid dreamer as being in a “void” or in “darkness”.
Again...not a lucid dream - this is an OOBE.
However, lucidity is preserved; internal speech, affect and cognitive function remain intact within this minimal environment.
Some sensory modalities are also preserved; kinesthetic sensations may be present (so that the subject seems to be “moving”) although somesthetic sensations (sense of body image) typically are absent.
There are perceptions of visual depth (e.g. the “darkness” has a sense of depth and size to it), but typically not visual perceptions of color or form.
The “darkness” can sometimes appear to have visual motion; it may “swirl” or “bellow”.
Because some lucid dreamers can undergo a loss of stability and appear in a minimal perceptual environment instead of awakening, it is possible for a lucid dream experience to consist of a string of lucid dreams occurring in typical or surreal environments punctuated by minimal environments (a multi-part lucid dream). That is, the lucid dreamer will be in a typical lucid dream, lose stability and fade from the dream into a minimal environment.
Techniques similar to those used to prevent lucid dream fading, such as spinning in place or inducing somatic sensations, can also be used to cause a sensorium to re-form around the lucid dreamer, giving rise to the second lucid dream. The second lucid dream environment may or may not be the same as the first. The cycle can then repeat. It is possible for a single lucid dream session to consist of perhaps six or more lucid dreams in typical or surreal environments punctuated by fadings or minimal experiences.
The following are accounts of minimal sensory environments from the authors’ records.
(DDG16)
“Found myself in the void. My mind was wandering in all kinds of thoughts. Then I noticed that I could ‘leave’ my body. I flew off through the void. Everything was dark, kind of somber, and I didn’t have a body. I had the desire to be somewhere. Soon a large, what appeared to be wooden fort appeared in the mist. It was still quite dark but I could ‘see’ now.”
(DDG31b)
“Though I was in the void, I was still being pulled along by this mysterious wind force. As I was being pulled along, a very beautiful rainbow colored sphere came rolling past me and it was very clear and well defined in appearance. I was very surprised because this is the first time I had ever actually seen an object in the void and I began to wonder what was going on. I quickly noticed that I was surrounded by subtle arrays of colored patterns. It was very subtle because the darkness of the void seemed to be covering over these color patterns, the patterns seemed to be behind the darkness. The colors and patterns were very intricate and I have no words to describe what I was seeing.”
(DDG61)
“In my imagination, I imagined flying off, but got pulled back again. This happened twice. Then, I dove off my bed straight downwards. I was moving straight downwards in the void. Far below me in the darkness I saw a square floating. In the square I could see colors, like a scene was inside the square. I stretched to grab this square and my arms stretched far below me like Plastic Man, and I grabbed the floating square. I pulled it up over me like putting on a pair of pants, and was thinking to myself, ‘I’m not gonna let this one go!’ I stepped into this square and was all of a sudden somewhere! I was very surprised. I was in what looked like a high school hallway standing in line with people going into a room.”
(SLB56)
“...I am looking at the image of an instruction book for a vacuum cleaner or some such appliance, knowing that I am asleep. As I focus on the writing the image stabilizes (and I have a sensation of opening my eyes) and I am able to read some but it is not interesting to me. Then my hands appear and I am looking at this piece of paper in bed. I think I ought to do the eye movements and so I follow my finger up, then down (I am very aware of the muscle strain in my arm and wrist, and feel the need to urinate). Then the dream fades.”
It is of interest to note that the lucid dreamer can “fade out” from both typical and surreal environments into minimal environments, and conversely, can “materialize” out of a minimal environment into typical or surreal environments (as DDG61).
As (DDG31b) indicates, the dreamer perceived “the darkness of the void seemed to be covering over these color patterns, the patterns seemed to be behind the darkness”.
It is almost as if the lucid dreamer’s sensorium is tuning in and out of stable patterns of perceptions, akin to tuning a radio to a radio station.
The following journal entry illustrates clearly how surreal and minimal environments can fuse, and fade into typical environments.
This example suggests that clues to understanding sensory consciousness may be found in the phenomenology of lucid dream perceptions:
(DDG64)
“I seemed to now be floating in the void. However, there were what seemed to be colored triangles moving around, crossing and spinning over one another making distinctly geometric patterns in front of me. The colors were mainly a yellowish green with red, orange and pink hues and they had the texture of clear and smoky, but smooth glass. ‘This is a weird view of the void,’ I thought to myself. I stared at these patterns wondering what the hell I was looking at. I began to focus harder and harder on these patterns, trying to discern some detail in them.
Then, as I was focusing, the most incredible thing happened.
I watched these patterns ‘solidify’ and transform into the scene on the dance floor of the club I had just faded from.
The spinning triangles were actually the dancing people in the club! I was amazed.
I relaxed my focus and the scene faded back to the spinning triangles.
I was thinking, ‘Wow! This is amazing!’ I tightened my focus again and the triangles again transformed into the dancers on the dance floor. This time I tightened my focus so much that the entire bar scene faded in around me! I was back in the bar again!”
What minimal lucid dream environments correspond to in physiological terms is unknown.
It is tempting to speculate that minimal, surreal and typical perceptual environments correspond with lesser to greater degrees of brain activation, respectively, during REM sleep.
Minimal environments superficially resemble the “thought-like” character of non-REM subjective experience (Hobson, 1988).
However, given the fact that it is more or less easy to re-establish a typical or surreal environment from a minimal environment, the minimal environment may correlate with tonic REM.
The time after REM onset may also be an important variable affecting perceptual qualities of lucid dreams.
The interrelated phenomena of stability, fading, and minimal perceptual environments during lucid dreams has interesting implications for our understanding of conscious processes.
Clearly, in these experiences, higher level cognitive functions of consciousness continue to operate in the relative absence of conscious sensory modalities.
We are observing in these phenomena some type of dissociation, or perhaps lack of binding, of the contents of consciousness.
Psychophysiological characterization of this phenomena would be of great interest.
No previous studies have presented data regarding the frequency with which lucid dreamers as a population or individual lucid dreamers experience the three perceptual environments we have identified here.
Published dream reports indicate that typical environments predominate lucid dreamers’ perceptions, although we have encountered cases where this is not true for single individuals, and it seems likely that individuals will have characteristic distributions of environment type.
For example, 52%, 96%, and 17% of DDG’s lucid dreams had at least one scene with minimal, normal, and surreal environments, respectively; the figures for SLB are 16%, 92%, and 5%.
Although the great majority of both authors’ lucid dreams take place in normal environments, DDG’s were significantly more likely to have minimal and surreal environments as well.
The differences in frequency are even more striking if we consider the extreme case of minimal environments, the void, without any content at all; DDG, 32% vs. SLB, 3%.
