I once felt that way too. Now, I just think of how billions of years passed before we came into existence and that doesn't seem to weigh on our mind or drive us crazy. When the brain doesn't exist to perceive time, time might not even exist at all.
@_AllCatsAreGrey_ @katara @AmberianDawn I heard one of the theories for why we dream is that since the brain is no longer receiving any external simulation, it creates those "hallucinations" to preserve it's own wiring and optimal function (particularly to preserve the visual system) because it's a use it or lose it kind of thing. If we don't see or study something for a long time, we eventually forget it entirely as those pathways in our brain fade away like a forest trail overtaken by the forest undergrowth. So maybe near death experiences, are for the same or a similar reason. Since the brain is dying, it tries to hold onto it's wiring and functionality for as long as possible to preserve itself causing so many neurons to fire all at once. While most NDEs are positive, the few I've heard that aren't are interesting. I'm pretty sure though death by a powerful anesthetic like N won't cause any NDEs though since it makes the brain slow down and stop signaling so much that the brain stops signaling the body to even breathe which is why people don't have dreams when they go deeply and properly under anesthesia for surgery (though apparently it can happen as people begin to recover and come out of anesthesia). My guess is the slower the death (starvation for instance), the more likely one will experience an NDE and maybe even a more vivid one too.
