When I was 14 years old I got involved in seances over a period of a few weeks. They do work. I couldn't explain the supernatural happenings. Scared me. Shocked me so much that I had to stop. I destroyed the glass and the glass board and alphabet on squares.
This also gives me cognitive dissonance. Evil spirits but no god? Still not correctly sitting in the atheist position. Must be still agnostic.
I believe what ever is out there in the way of evil spirits is also related to ufo's.
The small number of unexplained ufo sightings which amount to about 5%, are called residual ufo sightings. They seem to be related to people who engage in occult activities like seances tarot cards ect. In these cases, these people seem to have continuous experiences whith these sightings and may even become traumatised by them. As if they are being harrased.
