You’re welcome! I had a personal experience with this, too.

When I was a kid, my parents used to make me go to church and youth group stuff. We went to one of those “hip” events at Carowinds (like a Six Flags, Disney type amusement park). Before it started our youth leader said - to his credit - “No matter what you feel, DO NOT go down to the front when they call people up.”

Sure enough towards the end, I start feeling “the spirit”, and I’m the most skeptical, atheist/agnostic in the whole group. But I stayed in my seat. And when we got back to the hotel I was thinking “what the hell happened there?”

I’m back! I couldn’t find the specific thing I read, but I found something probably better, an actual study published in Pubmed:

Statistical analyses showed that the psychological disposition during the religious worship experience speeds up the physiological responses, which was indicated by increases in HR [hear rate] and RR [respiratory rate]. Hence, the activation hypothesis was accepted, and the pacification hypothesis was rejected.

I’ll try to look for it. It was a loooong time ago though.

I read an article years ago that explained why so many people get “religious” feelings at big revival-type events at Six Flags, Carowinds, etc, even if they’re not particularly devout.

There’s a thing called respiratory alkalosis (essentially hyperventilation) which makes you light-headed and confused. At it’s really easy to trigger by making people stand up quickly, sing really hard, sit back down, stand up and cheer, etc.
