well i have often wondered about how much the taking of drugs effects it all. For anyone who has ever taken drugs we all know it seems to open your mind one way or another. well before i started taking drugs i never had any ld's, sleepparalysis, thoughts i cant control such as hearing a thought when im thinking of another when i didnt put it there. but after i started taking drugs (not addiction style, just every now and again suppose its a social thing) i started experiencing new things in my dreams. it probably doesnt effect everyone the same, but with me i think drugs has help aid me to this new way of dreaming.
