I have a friend who is schizophrenic, as in on meds for it. He insists the voices in his head are demons. The voices tell him to do things, the kind of things that got him dfed years ago. The meds make the voices stop, yet he insists that theyre really demons. Despite overwhelming evidence that the spirit world probably cant be controlled with chemicals, he INSISTS that theyre demons. Why? He WANTS to believe, so he WILL believe.
My house is nearly 100 years old and it makes a pantload of noises at night, that and my cat jumping up and down off of things, including my bed. I also have had many many experiences since childhood with sleep paralysis, paranoia about demons, vivid dreams, and the like. In other words, ive seen many strange shapes, heard sounds, felt like i was being suffocated, held down, etc.
NOT GHOSTS. NOT SPIRITS. JUST MY DUMB IMAGINATION.
but i can only speak for myself, of course.
i lump this stuff together (probably unfairly) with UFO crap, face on mars, masonic conspiracy shit, hollow earth, mormonism, jwism, and anything else that gives people an exciting and somewhat delusional edge to their existence.
its more fun to believe in a "magical" world than a plain old rational world. trust me, i did it for years, i know what if feels like.
