text: i have a tendency to manufacture events in my head...? if i try to think whether or not something happens, my brain spits out memories that tell me i have, even though i distinctly remember not having those memories. is this normal? you obviously have an over active imagination. or you might possibly have add causing you to not be able to concentrate on what you are doing and there fore making you incapable of remembering whta you did causing your brain to make up something. i suggest you take an add test online or go to a docter. medicine can help with this.
