I still get a funny feeling when I think about this.
One Christmas back in 1980 my mom received Ouija board as a gift. I was 5, she would have been 22. Her best friend from down the street to visit Christmas Eve at night to share "What would you get for Christmas?"
She tried asking it, "Is there really a Santa Claus?" We put our fingers on the planchette and asked the question. After that, it started moving. The answer it spelled out was, "Only in the hearts of little children".
I was getting so nervous about it. I never played with it again!
