Good contribution, Para.
You've reminded me of something I read in John W. Loftus' unfortunately-titled anthology The Christian Delusion, which can be found on huffpo.
Valerie Tarico: Christian Belief Through the Lens of Cognitive Science: Part 4 of 6
In short, it talks about conversion experiences from the point of view of cognitive science. My own £0.01 on the issue would be that since entering therapy myself I've experienced essentially the same "religious experiences" I had in church, but this time (having been an atheist for a couple of years now) I was definitely
not praying to anyone. Instead, I was intentionally trying to access repressed emotions - I think instead the language and atmosphere of church occasionally triggered those and correlation/causation fallacy took care of the rest.
It scarcely seems implausible to me that a church setting would provoke this too, religions thrive because they do touch on emotional needs. It is just unfortunate that so many of them tack a lot of baseless crap onto the process that you're required to believe.
