as a dumb 12 years old, i played with one(ouija) with a friend. we were alone at his apartment, and his sister had one. so we got it down went to the livingroom and began asking silly questions and basically acting stupid. so i asked it, if it was real, it better show me a sign or else ill break the board, and as soon as i said it, the closet door in the foyer began banging loud as hell.

needless to say, we spent the rest of the day outside. and i havent touched one since.
