What you have are subjective anecdotes. If you approach it from an unbiased stance and take away any of the religious connotations, do those stories sound rational? They sound extraordinary and in defiance of what we know of biology, physics and so forth. If someone told you they were at an event and some girls hair turned colors suddenly would you be completely accepting of that story or be a bit skeptical?
Based upon your previous posts manga, what you seem to be stuck on is subjective stories which I had previously commented on in another thread. Refer back to the mention of the false memories and the Satan cult scare of the 80s/90s.
Here are some things to keep in mind:
1) People lie. For whatever the motivation, people lie and sometimes do it without even realizing it. It may be for attention or to elicit a particular response from others or to get some kind of reward or something similar but it happens, a lot.
2) People embellish. I separate this from lying because lying often entails fabrication whereas embellishment is on a smaller scale but often root to something that actually happened or was true but much more mundane. People embellish for the same reasons they lie.
3) Perception is unreliable. Our senses can easily be fooled - mirages, optical illusions, hallucinations, delusions, false memories, confabulation, cognitive biases, et cetera all show how unreliable our own perceptions are. This is why science relies so heavily upon objectively verifiable evidence - it is independent of our faculties.
4) People love mystery. We love mysteries and attempting to find out about the "unknown" and the "unexplained", however, much like what motivates parapsychologists (man I hate that term) its the pursuit that motivates them - no matter how much lack of evidence they collect they still continue and latch on to any small thing and call it evidence like a "cold feeling" or supposed fluctuations in EMF readings.
5) Explanations for supposed "supernatural" phenomena aren't "sexy". Most explanations are "boring" for lack of a better word. It's not exciting, shocking, scary, or awe-inspiring enough for most people. So many people prefer the more outlandish ideas because they are often steeped in mystery (see #4).
So, no matter how many stories like this you post you won't find any resolution but just skepticism to those extraordinary claims because those require extraordinary evidence and anecdotes from third parties is not extraordinary evidence.
