I too had a bad experience with the Ouija board. I think four friends and I had our hands on the board attempting to communicate. We had something talking to us, we knew it wasn't good. Everyone took their hands off and I was the last one to be touching it. A weird feeling started to engulf me as if my body was going numb. I was running in circles and jumping around to try and feel like I wasn't losing control.
One of my friends were reading from the bible at the same time. Slowly I started to feel normal again. The hand that had been on the Ouija last seemed to also have a greenish aura to it.
Since then I will not touch those things. I feel that a spirit was attempting to possess me.
