I posted recently about a paranormal investigator who places all ghostly happenings into 3 categories; Hauntings (residual replay where no interaction in possible), Ghost (active entity who can be communicated with and is aware of our presence) and Psychic (our own psychic energies manifesting either in the physical world i.e. poltergeists or just in our minds). I like it. It's neat and all encompassing. Not sure I buy it but it works. So, given this hypothesis then it "might" be possible (with a huge emphasis on might) that using a Ouija board acts to focus our own inherant psychic energies. By that I mean that the board itself is harmless and cannot be used to communicate with the dead. I have always said so. However, the act of using it, or indeed acting out some other ritual, may allow access to our energies or allow them to focus. This could then manifest something physical (movement of an object, poltergeist activity) or something more internal (visions, noises, voices etc). Even witnessed by several people who have become "in tune". This is all wild speculation (both on the reserachers part and mine) but I have also wondered over some of the physical evidence surrounding Ouija boards. The participants unwittingly control the glass on a subconscious level but, if what people claim is true (that they have witnessed other phenomenon; I've never seen any photographs or films - it's all anecdotal) then there must be a reason for that and their own psychic energy creating something seems slightly more plausible to me than dear old departed Aunt Mable coming back to throw a whisky glass around.
