[[but are not fully testable. ]]
Several common experiences are testable- such as the brain not getting enough blood and oxygen and a person’s peripheral vision loss and tunnel like white light before they go completely unconscious-
[[relate previously unknown information passed on to them;]]
We don’t know that they had never heard that info- they could have heard that info as infants or children, and had it stored away and when the NDE happened new pathways in the brain are opened up and stored info becomes available again- the brain ‘locks away’ certain info in normal brains- certain drugs, and NDE’s as shown in mri’s reconnect those pathways in certain circumstances- hence the ‘life flashing before our eyes’ syndrome-
As for ‘cli9nical death’ there is a state where a person is ‘clinically dead’ yet not ‘fully dead yet’ if that makes sense- many folks have ‘come back from clinical death’- which suggests that even when machines don’t register a ‘spark of life’ one still exists- God alone determines when to snuff that spark of life completely
I’m not suggesting scientific explanations and test results show there is no spiritual aspect to all this- however, some of them ore common experiences can be explained by science-
I know well what you mean about clinical death. My youngest brother died from chemical pneumonia when he was two years old. Fortunately, we had got him to the hospital and the family pediatrician was attending and revived him by a CPR type procedure.
Over the years, my brother has sometimes had premonitions of future events. I have no doubt about the circumstances because I was directly involved and fakery would have been impossible. Notably, returning from death is thought to sometimes result in unusual powers of perception.
