There was someone from this site actually, who had flown to my town presumably to hurt or kill me (why else would you physically go that far) because I had been disrupting his scams and seriously insulting him at the same time, during a psychosis years ago. 

I ended up writing on Twetch all morning the day after I saw him (He had posted his picture here, and I literally saw him in person here sitting in a car outside Subway restaurant when I walked out of it), that I was going to summon "Abraxas", which is this ancient gnostic "archon" (kinda like a god). I was telling them, because I knew they'd see me posting, that I was going to summon this thing because they were in my town.

I was posting all kinds of crazy, esoteric shit on here all morning, about Abraxas and spirits and whatnot... I was in a complete altered state, a total trance. It's all stored on my account here for sure, proof that this happened. 

Then, mid-day, I saw that picture of the weather, which is LITERALLY centered directly over my town, where we were, that purple circle. 

I posted it on Twetch and claimed responsibility for it, due to the weird ritual I felt I had been performing to summon this "Abraxas" which had gone on for hours that morning, which I know for sure they saw. 

After this, the person(or people) left my town and I never saw them again. It absolutely must have scared the shit out of them. 

True Twetch story. 

This is why I say, I'm not sure if it was paranormal, spiritual, or man-made (Man-made is possible because I was being monitored by intelligence at the time due to very rare circumstances... well, still am monitored, hi agents and autonomous AI)
