| | Astral Dynamics Mind-Split
Robert Bruce has a book called Astral Dynamics that might interest you (if you haven't read it already).
He talks about using "tactile" senses to project instead of visualization. A system he calls New Energy Ways (NEW). It is very similar to tai-chi, ki-gong and others energy movement systems.
He also talks about something called the Mind-Split. Very interesting concept. His theory is that the Astral body sometime projects, has an amazing experience, but the memory of it gets "copied over" by the memories of the physical body (which is still dreaming and sometime even awake) as the Astral body is flying around.
It sounds far fetched but I think he has a point because I've had double and triple dreams in which I am have two and three dreams simultaneously. Or two or more "dreams" seem to overlap and I can barely remember the one that was MOST important even though I feel like I've forgotten something extremily important.
One of the ways to remedy this is to be aware that it can happen.
