I use to meditate but have not done so in quite some time. What I did was very deep meditation. It is about basically putting your body into the REM cycle with your mind being complete conscious. I can tell you it is really weird hearing yourself snore and thinking it's annoying. Also it creates some pretty intense dreams/visions/images/etc.. It basically puts me into a state where I am in control of myself in my dreams but not exactly the dream. I can make myself walk, talk, etc in the dream but everything else in the dream just is there. It is basically like living another life, you also remember the entire dream. Sometimes it will only feel like you are out for 10 minutes though and then after ending the meditation it has actually been 3 hours. It is really intense.
Now how I do this is by getting into the darkest, quietest room in the house. There must be no disturbing noises. I then lay down and get as comfortable as possible, before turning on some ambient music, something like the sounds of waves. I then begin to deep breath and start getting into a state of sleep a little. Then I imagine a chest and lock away pretty much everything I am in this world and then I continue deep breathing imagining exhaling all the bad things in my body and inhaling fresh new air. After a few minutes of this, I will start to feel a disconnect from my body. My fingers, toes, arms and legs will start to twitch slightly and I will start to losing feeling in most parts of my body as all I focus on is breathing. My head also starts to feel lighter and also I feel like as if I am not just in my body but in the air inside the room. Once I feel almost a complete disconnect from my body and I can no longer feel my toes, or fingers, is when the dreams start. Sometimes I can control them completely, other times I am just dragged along. At any point though I am able to end the dreams and wake up.
I use to do this before going to bed every night and I would spend the entire night in complete control of my dreams and pretty much completely conscious to the world yet wake up feeling as if I had slept the entire night.
