newdimensions said:Ever heard of flashbacks? Some people get them after they have particularly strong experiences with hallucinogens. Their minds slip back to the state during the trip, kind of like smelling something familiar and having a memory pop up (I often smell things that aren't there because of memories, but that's another story)
Anyway, not that I'm saying this is a flashback or not, but it's clear the mind can do crazy things without exogenous substances. I've hallucinated while meditating, and I've woken up in the middle of the night only to have a dream continue, superimposed on my visual field. I've had this stuff happen both before and after I began my research with hallucinogens.
The point is, this stuff can totally happen, and science doesn't know too much about why, what endogenous substances cause it, where they are produced in the body, etc. And it doesn't matter too much anyway. What does matter is that it's cool, can be useful, and you should do your best to enjoy it!
I think flashbacks are related to PTSD, it makes the most sense in my mind. Even a positive trip that was very strong can be a traumatic enough experience to precipitate PTSD.
