What do you say about near death experiences where the person claims they've seen heaven or hell?
My late wife had many near death experiences before her brain tumour finally won, and she said it was just pleasant and peaceful with memories of loved ones including her cats who had passed, but also some people who were still around.
She/we believe it is just the delusions of a brain under those conditions.
If you hit two people hard in the back of the head, they will both claim to see stars, this does not mean they are astronauts, simply that they have had the same experience and experienced the same result.
Like wise when people come close to dying they see a tunnel of light and have a feeling of levitation, their brain calms them to face the inevitable before shut down.
Almost dying produces the so called near death experience, it is nothing supernatural, it is a natural reaction to a natural situation.
It;s electrical activity in the brain, thats what I've heard from the experts , scientists,theres also books
I've read about the two sides of the brain, they communicate with each other, like when people say that they are communicating with a god, interesting stuff.
I think the brain is not completely understood and as a result folks do try to translate something unknown into familiar images or reasonable scenarios. The brain is electrical impulses and firing synapses. If bits and pieces are not getting required nutrients during shut down (near death/oxygen deficiency), there is a still a need to reason out the experience. (Go toward the light... Trauma centers are VERY bright. ?)
I'm not a shrink or have any credentials but I think that may occur as your Brain shuts down that may occur because being near the threshold of death and then you recover and you do not actually die. We won't know what happens till we really pass on and no coming back.
