I was the same until I observed those things in action. I'm 60 years old now; and, I have had numerous experiences that have convinced me that the spirit realm is real. I have degrees in physics, math, and computer science; so, I'm not fresh off the turnip truck.
My experiments with the Ouija board occured around 1975 after observing people play with it. I was angrily scoffing from the other side of the room until I heard some truely unusual things that were completely untypical of any of the ladies playing with the thing. Later I conducted experiments that culminated with transmitting messages over hundreds of miles ... one board/guide to another. After a few years I could operate the pointer without another person helping. That is when the scary stuff started happening.
I'm smart enough that most people tend to stay away from me. That is one of the curses of being too smart in American society. I don't fool easily, and I know what I saw and what I have experienced.
So share if you don't mind.
I would like to hear or um Read!
I only fooled with one once and it didn't work. I did have a weird experience with one once even though I never touched it and it was still in the box!!!
