I never had a near death experience, but someone close to me did. They saw a white light.
Which is the effect created when the brain stops receiving oxygen. The edges of your vision are the first things to go, also usually before the loss of consciousness, so it creates a lighted-tunnel effect in the eye-sight that people remember seeing when they come back to full awareness.
Add this to the proven hallucinatory potential during NDE's, as well as the loss of sense that creates a weightless or tingly feeling, and it's easy to see why people frame it in a religious light.
The video I posted earlier might deal with it. If it doesn't, Shermer's writings on the subject ("Why People Believe Weird Things"😉 do.
