there was a guy who lived near me who fucked up and took loads f acid, by accident it was pure liquid. Anyway he was never the same, he halucinated alot. was really weird, acted strange and spoke to people who werenot there. i you can go too far and the brain can ever return to normal with some things. in your case i would guess a psychiatric problem is the case. Have u ever seen a doctor. or your a gifted psychic who can see spirits and peer into the spirit world dimension is my second diagnosis
