Well, I have had the sensation of becoming abstract concepts, if that helps. It seems that in all the dreams, my mind is consistently aware of itself, and in the same configuration that it's always been, but either identifies physically with something else or a lack there-of. Once I was floating up an elevator shaft that looked like N64 graphics, and was convinced that each door was an entrance in to different dimensions in which my mind also (simultaneously) resided in. Like going through each door would simply focus my awareness on to said timeline.
