I used to be one. Yup, me, the atheist, believer of only the purely physical. At one time I used to channel, etc. I was into auras, ESP, Edgar Casey, Shirely Maclaine . I gave readings. I believed I could transcend time into either the past, or future. I had a psychic journal, Personally, I found that it was quite easy to become engrossed. Once you get started, I found there were no brakes, you just kept going further and further, without any real assessment of their validity. While I was obsessed with the psychic world, it all made sense. But, then, for me, I slowly came to the conclusion that it was all self delusion.
