GingisK has posted the most authoritative "scientific" experience of the Ouija Board. Though highly educated, I do not pretend to compare my experience with his but do check out my post at #65.
It was not necessary to ask the questions out loud, especially when the sole operator. The entities are not made of matter, they really hear your thoughts. It is necessary for some people to speak before their thoughts are coherent.
The Ouija board is not an essential part of the process. It merely provides a focal point for the intent to communicate.
what is the manner of propagation, and at what speed do they travel? If the entities can even affect you or the planchette, what is the source of the energy that is doing the work?
I really don't have a clue. I believe that the planchette is moved by their influence on the motor system, so the energy of motion comes from our own muscles. The nature of that influence is a matter for which I have no theory. I had to assume that there is something we mortals haven't figured out about life and the universe. The observed phenomena did not fit with anything I know about physics. The only recourse, barring insanity, is to assume there is something going on that surpasses our understanding. This isn't supposed to be a cop-out, it is the best I can do when fitting the observations into my knowledge base.
I assume that the external entities can hear the thoughts, and seemingly sense other signals in our minds. I experienced one event where the entity expressed gratitude for the classical music I was playing, and said that he could hear it with our ears.
did you give fair consideration to the idea that the most appropriate and believable explanation is that your imagination was getting the best of you? If you rejected that, why?
Of course, I did give consideration to physical realities and even some sort of group-induced psychological effect. I started off a rather staunch skeptic, but was unable to reconcile the observations with anything I knew to be reality. It took a long time for me to acknowledge that something extraordinary was taking place. It is easy a lot easier to scoff this off than to objectively get ones belief system destroyed. The most convincing evidence that we didnt have an overactive imagination was the interruption of a session to get report that an absent member of our group just had a close call with a car wreck. That was verified once she showed up to the apartment. In another case, we sent a message to another group in another town without any other form of communication other than the boards. Imagination would be hard-pressed to provide those events, wouldnt it?
Bear in mind that all of this happened in the mid 1970s. Communications was strictly land-line based in those days; and, we did validate long distance communications. We knew well the disposition of the telephone in the apartment.
I dont spend any time with these things now. There is nothing useful to be gained, and I have a lot of things to do. The game THEY play is to influence your lifes decisions and perhaps tap into your sensory perceptions. They are very peculiar parasites.
