i see ppl when this happens i turn on the light and talk to myself tellin myself there is no one there i think the worst is when i have bugs crawling on my i can feel them and i see them once it got so bad i used sellotape on them to show my cpn but when the vision passed i had loads sellotape around the room with nothing on now i flick the bugs off if they dont go i know its in my head and i keep telling myself that i hope that helps xxxx
