Hey guys, I just finished watching the movie http://en.wikipedia.org/wiki/Altered_States" [Broken]. As a movie, it wasn't bad, but it was the subject matter that really interested me. The main character is trying to find out what exactly consciousnesses is using hallucinogenics and a float tank, and eventually becomes the very beginning of what consciousnesses is. Anyway, I'm looking for some books on this sort of thing. Obviously not general neuroscience, but stuff related to consciousness, altered states of consciousness, sense deprivation, hallucinations, etc etc.
