My first wife was into the ouija board, I did experience some weird things from it but it was a long term thing. Do I think it dismantled her behaviour ? No not at all. Then I had a girl friend that was into the tarrot cards and again some strange things happened and yes I do believe that there was some long term damage from it, not towards me but towards her. But then her mother made claims of being a with and they lived in a commune of witches in up state New York. I know that after her mother had passed away she went with her children to that community where all who lived in this developement were proclaimed witches. So I think it determines what you want from it or what you get out of it.
