I have also read about how many aspects of the NDE are just neurological artifacts that aren't well understood. I do believe in reincarnation, but I also think that sometimes many of the "funkier" NDEs could be due to the the person being pumped full of drugs (Suicide attempt, physicians trying to revive them, etc.) or maybe oxygen loss. And by funky, I'm talking about the ones where the person says that they partied with Elvis while riding a dinosaur and the like. But, instead of picking and choosing which are real NDEs and which are mind tricks. Or trying to decide if NDEs are physical or something beyond our experience, I think that we should see how they effect the person who experienced them.
Example- Someone was a jerk. Cruel, mean, uncaring. They die and are revived or come back on their own. During their time "away" they describe being judged in a Christian hell-like experience. After the event, they come back a different person. Better, more thoughtful. Maybe even apologetic about their actions. Whatever anyone thinks is going on, the literature is full of such profound changes in people and they definitely cut across all cultures.
Let me give you my NDE experience so far. You'll see what I mean by "so far".
When I was 13 I was attacked and strangled. What, who, where, why- I'm not going to say right now. Too painful. But, I can say that towards the end, I did see, just for a moment, a bright light that looked so familiar, warm, and inviting. Now, even before this horrific act, I already believed that we keep coming back. As I've posted in other places on this forum, I've just always felt that way. I just had never researched it before. So, I knew nothing of NDEs or tunnels of light and the like.
Long story short, thanks to this event I have permanent swallowing problems. Pains in my neck that can't be cured with surgery and miracle pills. And I also have issues breathing when I sleep. As in I often will wake up choking.
Last year I was sleeping. I found myself surrounded by darkness. Not the kind of darkness you get when you close your eyes. Deeper. But it wasn't scary. I felt like I was floating. Not dizzy or "high"- floating like in water. I didn't have eyes or a body, but I existed and could see. I felt good. Again, not "out of it", but better than I had in years. No aches, no pains. Then I heard something. Like it was below me, far off in the distance. The sound of someone gasping for air. "Who is that?", I thought. Then I thought, "Oh yeah, it's me.", and I laughed. At that moment - - I wake up, taking in a big gulp of air. No fear, no terror.
I have lots of fun medical problems, any one of which will most definitely kill me one day. I'm afraid of lots of things. But, I've never been fearful of death. As in- ever. Not even before the age of 13.
Take of my experiences what you will.
