So, let's get this back on topic!
When I was a teen a friend had been experimenting with the ouija board and said that she was getting all kinds of messages that she was evil and such. I was very curious and agreed to try it with her. She told me to ask it anything I wanted. I asked it a lot of questions that my friend didn't know the answer to, but I did, and they were all right. I wasn't pushing the little thing either, it seemed to move of it's own accord. It didn't say anything else, no comments about evil or anything else!
Well, one of the questions I asked the board was how old my mother was. I got the answer that I was thinking, but I realized later that night that my mother had recently had her birthday and wasn't the age I was thinking any more. To this day I believe my subconscious mind was guiding the little thing (what DO you call it? LOL) around that board. I know I didn't do it on purpose, but unless some spirit was reading my mind to get the wrong answer, it just came from me.
I do believe that it would be possible for some other entity to control the board, that just wasn't my experience. I agree that if you choose to experiment with the ouija you should try to focus your intent to the positive before beginning. If you are having negative experiences you should probably stop.
