Warlock,
Working in a psych hospital turned me from mystic to skeptic, because I was an eye witness to the power of the mind.
I saw a patient with hysterical paralysis. He truly believed his legs could not walk. All tests were negative. As soon as we counseled him about the stressors going on in his life--which he conveniently avoided by not being able to walk--he instantly came out of his wheelchair. He still believes he was really paralyzed.
I saw several women give birth to invisible Baby Jesuses, some postmenopausal, all not pregnant. They had labor pains, did Lamaze breathing, etc.
The staff perpetuated lots of folklore about psych patients being possessed by demons or having magical powers. One, said to have the bionic hearing ability, always wanted to have the same room when admitted. Viola, the meeting room where staff discussed patients was connected to her room by an air duct that allowed for easy surveillance.
Another was said to have supernatural strength and 10 staff persons could not control her outbursts. I saw staff easily control her outbursts for years.
