Two ouija board stories:
1. Buddy of mine from High School and I roomed in the dorms first year of college. He went down the hall to join some people playing with the oujia board. He said they did the routine, and something came on who's name was 'AB' and it would keep repeating those two letters over and over. They didn't get much answers out of it, mostly just that autistic like repetition.
They were about to wind down when something else took over and spelled out: 'I AM AN ANGEL OF THE LORD. BURN THE BOARD NOW.' That's when he hiked out of there back to the room and told me the story immediately after.
2. Another buddy of mine years later who was a practicing Christian walked in on some younger friends or relatives playing with the board. He told them not to mess with that stuff and knock it off. After they left the room he put his hand on the board and said 'WHO ARE YOU?!?!'. He did that several times, and all the board would spell is 'F*** YOU!'. He finally told whatever it was to take a hike and get out of there, and that was the end of that.
And that is why I don't mess with those things.
