There are two categories of NDE’s.
The subjective kind that can’t be verified, and the objective kind like in post # 5.
Mine was not an NDE, it was a death experience. Full blown.
In the last 30 years I’ve helped many people with various death experiences to understand it. There are many variations.
Many of the people claiming to have had an NDE, have not. Even famous ones who wrote best selling books.
The experience is so profound that it changes your life. When you recall the memory of it, you reexperience it each time.
The ‘subjective’ kind is greatly verified in the subsequent lives of the individuals who have experienced it. There is plenty of anecdotal literature on this.
The problem with this stuff is that it doesn’t give itself to current scientific standards and scientific study. It’s very difficult to get funding for something that is not reliably repeatable, or doesn’t produce material profit.
I look forward to the day when there will be enough interest - and courage - to fund new exploration into ways of properly studying these ‘things’.
