near death experiences?

I doubt it.

No because during near death experiences your brain releases chemicals such as DMT due to lack of oxygen causing hallucinations. Also the people who do see "heaven or hell" in their hallucinations tend to be religious anyhow so it is really biased evidence. There is no proof that they have been to any such place and since we have scientific explanations for why these phenomena happen we can safely rule them out as evidence for heaven or hell

Reduction of oxygen in the brain's bloodstream can cause all kinds of delusions.

Did they? Or did they think that they did because that's what their mind told them?
