I don't know if an update of N=1 will alter your posterior or not, but I have an uncle (not a particularly religious man himself) who had a 'dream' while undergoing risky surgery, that he had 'left', but saw his grandchildren praying to the Virgin Mary and the Virgin Mary interceded and sent him back. This is already weird, since, technically people don't dream while under the knife, unless the anesthetic has worn off. In any case, at recovery he was told there was a moment during the operation where he briefly 'died' on the table (whatever that means) but then spontaneously awoke and the surgery was smooth sailing after that. And it was indeed true that the grandchildren were praying to the Virgin Mary specifically at the time of the operation. I'm a bit fuzzy with the details because my information is second hand (my uncle's wife related the story to my mom, rather than me directly), but it
is true that he had a terminal condition (I visited him in the hospital back when we thought he was close to going), the operation was not meant to be curative, only palliative, and yet somehow he's now completely cured and a changed man since that event.
In any case, not claiming this proves anything, of course; obviously there could be lots of explanations; but I remembered it because it does disprove the "people don't see religious figures in these visions" claim (albeit with an N=1). That's not to say I haven't heard of many similar accounts, but those had all been 3rd party accounts; this is the first time it came from a family member.
