I have not read any in a few years but I have read quite a few in the past. When people are declaired dead and can describe what others were saying and doing in another room, there’s just no explanation for it.
They say they see relatives who tell them it’s ‘not your time yet, to go back’ and they really don’t want to!.
People have tried to say it’s something happening in the brain but that won’t explain seeing and hearing things in another room. Frankly, it encourages FAITH in my opinion.
Evidence of the Afterlife: The Science of Near Death Experiences by Jeffrey Long, MD. (this is a bestseller-fascinating)
