Here is an "experience", an anecdote that I may have heard here or elsewhere...
A girl (or boy or adult, doesn't matter) got up in the middle of the night and was about to go into the kitchen when from the hallway she saw the kitchen chair TWIRLING around. She was freaked out, knew it was demons and was about to flee the house. Well, she got her courage up and peeked back in the kitchen -it started spinning arond again!
She took another step into the kitchen and looked closer. Her dog had somehow twisted its leash around the base of the chair and was frantically trying to get himself unwound from the chair... in effect, twirling it around.
Just because the girl could not explain why the chair was twirling did NOT make it a supernatural occurrence...
We don't know the exact reasons why everything happens today but should not assume just because we don't underrstand a phenomenon that it is superrnatural
What about epileptics?? In the bible and in middle aged people were POSITIVE they werre possessed by demons- the was NO OTHER explanation. Of course we know now because science has advanced and we continued to look for a naturally occuring cause for these "fits"... you can see how the example of epileptics can apply to our group here...
