Real religious experiences, the sort where you get one, say "Oh, I just saw God" and spend the rest of your life in a monastery trying in vain to capture that sense of connection again

I know an atheist who gets these. She used to think it was future superintelligences talking to her, but eventually she asked herself some very hard questions and managed to realize it was just a brain storm. It's one of the most heroic acts of rationality I've ever seen anyone perform.

But considering that some atheists do get these involuntarily and the vast supermajority of religious folk never get them at all, why call them "religious experiences"?
