During a near death experience, the brain starts to lose oxygen.
The brain shuts down any "unnecesary" tasks to conserve oxygen: first by decreasing the center that controls vision and sound, as well as input from the nerves are ignored. The brain only works w those tasks that are necesary to survive: making sure you breathe, that your heart pumps in a rythm, etc.
From here: the "black tunnel w the light at the end" and the lack of pain.
When lack of oxygen, brain goes into what is called anaerobic respiration. This produces energy to keep the brain alive for a small period of time, but is too slow w keep up w the demands and it causes toxic by-products. lactic acid being one of them. This causes changes in the way that neurons communicate w each other.
This causes the peaceful feeling and "out of body" feeling. Same reason why people feel high when smoking pot or taking any other hallucinogen that sends chemicals that alter the pH of the cerebral fluid and way that neurons communicate.
When oxygen is being restablished, the brain immediately opens back all the tasks that were shut down at the begginning: eyes and senses being the first. Input from the nerves need to travel through the spinal cord, so this is more far and this comes later in the recovery process. However, due to the accumulation of lactic acid the brain still doesn't know how to process this information. It is stored in the long memmory, which is one of the first areas to recover.
This is why many people remember seeing and hearing things that were said in the OR, but never felt any pain, were incapable of moving, and still felt peaceful.

I've had countless near death experiences both personal and friends.( we dive for ancient wrecks for the past 40 years) You actually kind of get used to them. They are always scary but easier on the "soul" as we have learned to control our panic. I think a state of panic occurs when your conscious mind runs out of solutions for a rapidly evolving situation. That's when you switch to panic mode and your brain will try even the most amazing solutions to your problem. A lot depends on what your beliefs are. My life never flashed through my mind. There is never enough time for that you are too preoccupied with saving your *** or your friend's ***. But you do get flashes of memories. Never the same. Some are significant Like your wife or kids and some are insignificant like dancing in a nightclub. Others pray see light angels you name it. It is a very personal experience. Doesn't get more personal than this.

I've only had one near-death experience. Giving birth to my first child. Both our lives were at stake and I was so tired from the contractions that I just let go. I knew I had no control. For me it was peaceful. I felt ... free.
I heard an old railway engineer tell the tale of when his train de-railed. The head end (the engine) had slipped into the icy waters of a glacier lake. It was late at night and he'd been down there long enough that he figured it was game over. During his attempt to exit the engine he marvelled at his attraction to this boulder. He sat upon it and simply inhaled the water to end his life as he didn't think he'd make it anyway. He was miraculousy recovered from the depths of those murky waters. He has no recollection of it. And he was pronounced dead upon retrieval but obviously that was not the eventuality. He lived to tell the tale of being, momentarily very much at peace. Curious, don't you think?

Nothing that extreme. I choked on a brownie when I was 7 and I remember things getting dark, like I was looking through a black tunnel but I think it was because I was about to pass out. A few years later, I started to drown and my life flashed in front of my eyes, seriously. Visions from my entire life and every feeling I ever felt all hit me at once and I knew I was dying. It scared the crap out of me because I had no idea what was happening. That was not a peaceful feeling. I caught my breath though and I didn't actually die. I've never been pronounced dead and seen that 'white light' that people talk about though.

I am 40 now but I remember very well my near death experience and I was 12. I will do my best to describe it. I was traveling down a very bright tunnel but it was very billowy and it smelled of roses and as I was going down this tunnel I say my grandparent, As I got closer apparently they began CPR on me and it felt as if I was grab by the center of my back and pulled back very quickly. It is very peaceful and I do not fear death now because I know what awaits me. Granted I have more family members on the other side. And don't' get me wrong I am not in a hurry to die, I am just not afraid of the thought.

Well from a secular standpoint
nearly dying usually involves damage to something or other...the same effect that near death experiences cause can be duplicated by depriving the brain of blood though g-forces
But surely there's got to be more in life than just fading away...

Near death experiences are illusions. The subconscious mind becoming active during a high stress event on the body. It is the minds way of protecting itself from extreme or prolonged pain. Whatever your dad experienced was nothing more than perhaps a vivid subconscious dream.

Near-death experiences have been recreated under circumstances in which there is no danger of dying. Just ask a test pilot - 17% of them have NDE during training. It turns out it's just your brain freaking out. Those guys were in no danger of dying, but they thought they saw bright lights, dead relatives, out-of-body experiences, the whole works. Just your brain freaking out and trying to calm you down so you don't put more stress on your body.

No one has been on the other side. You cant get on the other side unless you are all the way dead. When you are all the way dead you don't come back. People who are near dead are prone to hallucination. That is what is called near dead syndrome. This is the real world.

I almost died. I remember my life flashed before my eyes in a second, and I realized it was the end. But there was no bright white light or anything like that. I was drowning when this happened.
