It was not a prayer meeting.
Except...
quote:
We were praying together in agreement, and we were becoming at peace with our relationships to each other, the world in general, and God as we knew Him.
That is a prayer meeting. Maybe spontaneous but none the less ...
But that's a nit pick.
Others here call your memory into question. I'm going to go the other way. I believe you experienced, in general, just what you said, though I cannot gauge whether your remembrances of all the exact details has not been, as Larni put it, "redacted" in some respect. I have no reason to doubt your experience since you are not a dumbshit with a demonstrated penchant to make up tall tales and because such catastrophic mental breakdowns are not unknown in our species. Further, I believe that
you believe your remembrances exactly as you have relayed them. Frankly, no one else here has any reason to doubt you since, though through the topic you juxtapose demons and your experience, you do not come right out and claim any demonic presence.
I think the setting is key to your remembrance of that tragic event. You are a theist and gods, devils, angels and demons are part of your world view. I can understand why you might see this event in terms of some supernatural encounter.
But I also believe you are not some crackpot ready to jump to the first conclusion that enters into your religious head.
Consider that in the natural synaptic/biochemical makeup of human brains breakdowns do occur, and though " ... one of the guys with deep blood red eyes biting himself and emitting deep growls ..." is certainly extreme, there is evidence to suggest that such an extreme can have a natural cause. It may be well out there in the tail end of the bell curve but natural disease can produce such rare tragedies without resort to invoking demon possession.
Ultimately, Phat, the conclusions you draw from this experience are yours to make in your own way in your own mind. For you demon possession may be an alternative. But keep in mind there are others.
And the latter are not off-the-wall nutty like the former.
