A couple friends and I talked with a ghost with a Ouija board.
The planchette moved from letter to letter. And we determined it was a 19 year old woman. She was born near the turn of the century. She'd worked in a hospital, treating many ill people before falling ill herself. She mentioned a war. She seemed to not know she was dead.
We agreed the spirit must be someone who died in the plague following WW1. I pointed out that I've read a bit on the topic and remember a story of a 19 year old girl much like the one we're talking to. I assured them I had not consciously influenced the planchette... this memory only came to mind after the spirit told her story.
"So, you don't think she's real?" they asked.
"No, I think we unconsciously control this, and it reflects our own minds back at us", I explained.
Instantly it was like I had pissed on the carpet and ruined the party. "But isn't the natural explanation the interesting one?" I asked. "Our imaginations did this!" It was physical/psychological reality that intrigued me. But it was supernaturalism that intrigued them.
That's why I find the Believer mind to be interesting, in a dismaying sort of way. Because they want more wonder in the world, by finding no wonder in the world.
