My mom bought one of those two million boards in the 60’s (spittin’ image of the one you show). She held one session with me (I was 9) and put it away as if it had burned her fingers. She was convinced we were surrounded by spirits at all times and put a deep fear into me over it that took 30 years or so to dispel.
A decade later a “friend” used it to manipulate me into believing in it so strongly that I took verbatim notes and tried to live my life according to the “advice”. He then told these stories to others and used me as a laughing stock. I wouldn’t learn this for another ten years.
So, I’m not a fan.
Great read, though!
