I find it interesting that strongly religious people reject this notion of communicating with something not physically present, yet they pray. I've always wondered what they imagine is happening when they pray. Perhaps they think nothing is actually happening. Something like a Ouija board does seem to provide a "reverse channel", using a process that must be similar to prayer. The rub is, you don't know the identity, intentions, or the power of the entity with which you communicate.
People must be capable of telepathic communications with each other. A person can "send" and "receive" to some outside entity, so it does stand to reason that the transceiver apparatus in people should be more general case than needed for these Ouija communications. I guess that is just a little out of reach.
I do know that I experienced that Ouija board with total disbelief at the outset. Only by observing and experiencing the feel of the pointing process did I alter my viewpoint. After a few years, observed results were considerably more sophisticated. Understanding that there is indeed a spiritual component to life is one positive aspect to these experiences. Extending this concept to general telepathy is more of a stretch; and, I didnt pursue that in any manner.
It does not surprise me that you reject this whole idea out of hand. Few people are open-minded about spiritual matters. Religious people also reject this even though it tends to corroborate life-after-death notions and the existence of invisible entities that are so crucial to religious beliefs in the first place. Ive always been a little on the fringe. You do not irritate me by assuming Im feeding you a line of BS. My experiences reinforce my beliefs, and also confuse my beliefs. I have benefited from the experience, so I have no need of acceptance from anyone. I would like to converse with someone on this matter in order to enrich my own knowledge.
In more recent years I practiced auto writing. That is pretty weird. You can do this by yourself with nothing but pencil and piece of paper. In the end, it is an enormous waste of time. That is a waste of your life. If you do those things an unseen entity requests, you have abdicated your life even without actually being possessed. Ask a Catholic Priest of possession is imaginary.
