Exactly my point, like I said I seen that myself along with others, so it's not just my imagination, I'm willing to be open to having a natural explanation, and I will admit that it's hard to believe, when I see same claims by exorcists, along with other symptoms of victims it's very hard to fall back on just the mind or illness, one other symptom is when victims are prayed on or touch religious objects they turn into aggressive behavior, one would have to ask why would mental illness produce such effect on that person.
Like I said I'm open, I have nothing to prove to anyone.
