I've been using a ouiji board called the Pyschic Circle for about a year, and sometimes I do get some mambo jumbo from it which I can't really make out what it is telling me but I have to say it has predicted a few things for me.
I stopped using it for a while when I thought the things it was saying weren't coming true then I went back and read my notes from it and realised it had actually told me my ex was going to leave me but I read what it was saying completely wrong, because of the way it tells me things it's like someone from a foreign country, when it said to me things like his name then go, or goodbye and stop etc, I took it wrong and expected us to be going on a trip. It also told me to push my father to go to doctor as he was close to a heart attack, 6 months on my dad had two, but then again I read what it said wrong and because it mentioned my mum I actually thought is was telling me about my mum's father that he had died of a heart attack or something. There has been a few things I misunderstood but when these things have happened then I realise what it was saying to me and slowly understanding the words it uses what they might mean.
But I have to say I am still doubtful of it and what I'm been told, and always try to protect myself as I have before gotten a trickster. The thing I noticed when I did get the trickster was that I felt very low after a session with it, where as normally I would actually feel happy. I sometimes even wonder if it's my subconscious moving the planchette, I don't really know, I'm sort of stuck in the middle of liking it and not.
What I would like to ask people with more knowledge than myself is how is it, that through a oiuji board that you are more likely to bring any spirit in or the lower spirits, rather than when you are doing cards or trying to connect with spirit guides in other ways. I mean this is really a piece of cardboard with a glass moving on top, so I don't really understand how different it is to using cards, a pendulum or other devices.
