Question about the whole NDE concept and Dr. Jeffrey Long

Welcome to the forum

I remember reading there is a very good explanation for the "bright light" a lot of people see, but I can't remember where I read it.

Your brain hallucinates under extreme conditions. That seems to be the most likely explanation. As Alex said, we're all very similar so similar experiences aren't that surprising. Where details do come in, such as religious stuff, it tends to be the mythology the person has been most exposed to.

There's no need to make statements like, "Nothing else at all is going on here". Science doesn't work like that. Science deals with what we can test. If a coherent, testable hypothesis is formed regarding anything else that might be happening during these experiences, then people will be all over it I'm sure. But just reading anecdotes and coming to conclusions through those is hopelessly unreliable. It's well known the brain is not experiencing just real things already, at this stage.

Science doesn't "know everything", but that's not a license to make stuff up, as woo-style people tend to do. If their methods of finding out what they claim to know are rigorous, then they too are science.
