My experience right now is different than 10-11 yrs ago and different than 20-25 yrs ago. At that time I still believed the demons controlled everything. Currently I still believe in a spirit world but I don't think it only consists of demons. I do not fear the demons anymore but avoid anything connected with the dark side of divination.
I own several Ouija boards and have never been had them speak to me. I just starting buying them to collect. I own numerous tarot decks and use them at times for personal help. I don't have more than the usual nightmares.
The things I used to believe the demons did, turn on TV's etc turned out in our case to be our neighbors garage door opener. I can usually explain most things but have had a few things happen that either were supernatural or I just don't have an explanation for yet. I know what I have experienced and would not tell someone else what they experienced.
I enjoy talking about these things but often the threads get derailed by those among us who feel they must tell everyone who believes in angels or the spirit world they are crazy and should see a psychiatrist. white Dove is right -if you are able to contact the spirit world you won't need the Ouija board or tarot cards or anything.
