I think it's pretty interesting that as
@Eventhorizon said you can be lying in bed and imagine yourself to be in another time and place and instantly feel as if you are actually there. Memory is such an amazing, poignant thing. It reminds me, although this is a different phenomena - of how strange it is when you are staying somewhere strange and you awake and can sometimes temporarily be dislocated in time and space, like your 'unplugged' from the circuit and have no idea where you are.
I was thinking recently about several memories that I have from childhood, They are a bit like peak experiences I think because as they were occurring I had the sense that these moments in time were somewhat 'timeless' and that I would always remember them and they have actually remained as 'crystallised' experiences and feel like mini poems of a sensory, experiential sort (if I can describe it like that).
But then other types of memories just 'come up on me' out of the blue, in a way which I think is most often a pleasant experience. Memory is really the sum of us, who would we be without our memories? Also the way that we store and interpret these memories was dictated by us and our particular perception at that time.
It's a huge and interesting topic of which little is known about. In my limited knowledge on this several things come to mind,-
When we remember we are also recreating our memories so that they evolve and change (to a degree) as they are 'reenacted' (apparently), therefore in line with this research there is no one 'true' experience of a memory because it is always morphing to a degree...
In contrast to this as the olfactory system, or other of the senses are triggered we seem to be instantly flooded with sensory data out of the blue, (this seems to be different to the more 'consciously remembered' memory).
Also, the experience of remembering or thinking about something is the same (in terms of brain patterning) as actually experiencing it (if I'm remembering this right)..woa...yes, so in this respect, on the memory plane the time line does seem to dissolve.
I'm not sure though how I experience memory differently as an INFJ. Perhaps it is to do with the intensity of the sensory impressions that are experienced in remembering? Or the impressions that result afterwards through Ni... But then sensory experience triggering memory happens for all the types as far as I'm aware, so I don't know how it might be different for people with Ni. It's a huge fascinating topic much like consciousness and dreams.
