When I was probably in the 5th or 6th grade, we were at a family friend’s house. Myself, my youngest brother, and their oldest daughter who I believe was 16 at the time. We were in her room and playing with one of the Parker Brothers cardboard Ouija Boards. After we were done, it was sitting on the floor and I was sitting on the bed. I made a comment about it being stupid. All of a sudden, it started shaking, lifted off the floor, and came flying at me. It was hurled with so much force, so fast, that when I ducked and it missed me, it buried half way into a sheet rock bedroom wall. I have never messed with one since.
