Sorry about the length of this post. Some times you just gotta get things off of your chest. S
For the uninitiated, an NDE is a near death experience. I watched about ten minutes of a documentary on NDEs last night before turning it off as I realized it was unlikely I would learn anything new. (I have read a great deal on the topic over the past decades . . . a great deal. Reincarnation, too. I was a teacher and reincarnation is very attractive to teaching mentalities; basically you have to learn your lessons or it is Summer School for you!)
The primary example in the documentary was from a very credible witness, a surgeon, who was convinced that in a kayaking venture she died and then lived again. This included being underwater for “ten minutes.” And when her body was dragged back to the surface, she was grey and her eyes dull.
She recounted a great many experiences that “occurred” while she was dead. And I have no reason to doubt the experiences, just the interpretations of them.
Allow me to segue to a related topics: dreams. I remember one time turning out the lamp on the bedside table and falling asleep immediately. I fell right into a dream state, a complicate long dream which ended so upsettingly that I started awake. I turned on the lamp again, and the bedside clock showed that a grand total of five minutes had elapsed.
I Googled the question just now: “How long do dreams last?” and one of the answers was “The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes.” Apparently the Guinness Book of World Records claims one dream lasted over three hours! Dream researchers also point out that our time sense in dreams is much faster than when awake, so a dream that really took only five minutes could seem like much more time.
Now I mention dreams in a post on NDEs because they have been studied and, in essence, are both creations of our minds. My dreams, at least the ones I can remember, seem to be placed in locales that are familiar, so it seems that those locales are plucked from memories. Also, some of the people in my dreams are people I knew or knew of. (In college I had a recurring dream of having phone conversations with Richard Nixon, he in the Oval Office and me in a phone booth (a phone booth in my college dorm with which I was quite familiar).) So, it seems that dreams use imagery available from visual memories.
So, how do we account for the experiences of people surviving NDEs? (Note People who do not survive their NDE never get to report their experiences.)
I am glad I don’t have to study such things in detail because there are a great many difficulties. For example, many of us think that when we die it is like a light switch being flipped. One moment we are alive and the next, we are dead. This is definitely not the case in most cases. It might be the case of a sniper’s bullet ripping through your brain case at 2500 feet per second, but most of us “rich Americans” don’t die abruptly like that. So, how long does it take to die? Well, if that surgeon’s experience is correctly stated, she was underwater for ten minutes. She could have held her breath for probably 2-3 minutes, but since her lungs were not full of water, she apparently did not inhale while submerged. So, let’s say that she began to die after three minutes underwater, and was dead for seven minutes before her body was pulled from the water, then a couple more minutes were needed before the CPR techniques that saved her life could be marshaled, so let’s say that she was “dead” for ten minutes. And she was then resuscitated, so apparently, in that one case, dying wasn’t complete after ten minutes of the process had elapsed. (She recovered all of her physical and mental properties (after her injuries healed) and is back on the job as a spinal surgeon, I am glad to say.)
My brain is clamoring, reminding me of the medieval crypt bells. These were bells that were placed above crypt doors so that people who “resurrected” could announce that they were trapped in the crypt. Now, back then people were placed in crypts with no embalming and sometimes in wait of a funeral, but this time period, from “death” to internment, to resurrection, must have been at least several hours. My feeling is that the instances documented in which “dead” people woke up in crypts were cases in which the people were not really dead, rather in a deep coma that led people to think they were dead.
This brings up the topic of “death” both from a legal as well as a medical standpoint. From a legal standpoint we have statements such as “Two categories of legal death are death determined by irreversible cessation of heartbeat (cardiopulmonary death), and death determined by irreversible cessation of functions of the brain (brain death).” I think the key word in these criteria are “irreversible.” So, if their heart stopped or their brain function ceased, if that were reversed, then they were not dead legally. So, that leads us to medical criteria: how do we detect that hearts and brains have ceased to function?
In action-adventure movies, one of the good guys takes two fingers and places them on a body’s neck (feeling for a pulse) and finding none, pronounces the guy dead or alive (this has the cinematic advantage of only taking seconds of screen time). In medical movies, someone is on an operating table and has a heart monitor hooked up (which we can hear beeping). If the heart monitor indicates that the patient’s heart has stopped, they get out the paddles and deliver electric shocks to the heart and sometimes it starts back up. Since the heart stoppage was reversible, the patient wasn’t legally dead. But medically? A medical dictionary states “Death is defined as the cessation of all vital functions of the body including the heartbeat, brain activity (including the brain stem), and breathing.” They go on and use the word “irreversible” just like the legal people do. But what do doctors do to determine that someone has died? Once again, Google has answers!
When their patient starts to show signs of death, it’s common practice to check for a pulse, pupil response, and heart sounds. Using these three indicators will help the doctor decide whether the patient has any chance of survival. Of course, if the doctor or nurses tried resuscitating or reviving the patient, it’s also important to note how long they tried and for how long the patient was unresponsive.
If a patient is in a coma, their doctor will also check for signs of brain death, including irreversible brain and brainstem damage, an inability to breathe on their own, and, again, a lack of pupil response. An EEG, a test that measures electrical activity in the brain, will flatline when all functions in the heart and brain stop.
Again, the only criterion distinguishing the dead from the dying is that word “irreversible” and that means attempts at resuscitation have to occur and fail, for a death to be certified.
It is hard to separate actual science from legal ass coverage procedures, so all we can say is that determining that someone has died is quite difficult.
It can be argued that all of our NDE testimony is from people who didn’t die, their death signs were clearly reversible, so they fit neither the legal nor the medical definitions of being dead. This is why NDEs are called near death experiences, of course.
But what can explain their experiences? We need to carefully separate their descriptions from their interpretations. People are seemingly very ready to invoke the supernatural, but that is not warranted, in my opinion. For example, dreams that take only seconds and seem to last hours are examples of things our minds can do. So, if we become unconscious (which we do sleeping, no?) and we think we have died and claim that we observed the process from above and can describe it in detail; is that “real?” The entire “death” sequence could be created as a dream sequence either before the brain ceases functioning or after it resumes. (Memories seem to persist a long time as the example of the surgeon above reinforces; she apparently lost none of her medical knowledge.) So, the experiences recounted may seem to have taken a long time, but that’s dream time, not real time.
The Air Force did some interesting research when they started doing centrifuge training for pilots. When jet fighters became so fast and so maneuverable that when movements became extreme, the G-forces caused pilots to black out as their blood was pushed out of their brains. This was disastrous for both plane and pilot. So, the AF created flight suits that squeezed the pilot so his/her blood would be harder to move but they also instituted centrifuge training so pilots would become familiar with G-forces and how they affected their bodies. Interestingly, pilots were getting back in line to have another session in the centrifuge. When queried, they sheepishly responded that just before passing out, they seemed to experience a tunnel of white light and had an experience of incredible peace and joy. It was a real high, they said! Apparently when the brain’s optic nerves got starved for oxygen, their bandwidth decreased so that only a central dot of light was sent to the brain, and the brain, thinking the pilot was in distress, flooded him/her with endorphins to block any pain or discomfort that might reduce his/her survivability. Hmm.

As to “hovering” above an operating table and “observing” one’s own death, as a child I used to play imagining games, one such was pretending on my bed at night that I could see through my knees. Often enough my pajamas had holes in the knees—I was hard on clothes—and I could even see the frayed edges in my kneesight. I could see my whole bedroom from the vantage point of my knees. How hard would it be for one’s brain which observed the operating theater when rolled in (and many others in the movies, etc.) to construct a dream-like movie of what was going on. How much was going on? Were people coming and going or were they all just standing around working on you. And, even if you were unconscious, your ears would continue to function and send signals to your brain, and . . . und so weiter.
So, what can we learn from NDEs?
#1 Dying takes time. Some people die instantaneously (blown to bits by an IED) while others take many, many minutes, if not longer.
#2 Dying is complicated. Even doctors struggle from time to time in making death declarations.
#3 Mental experiences while in the process of dying are about as easy to interpret as are dreams, which means bloody difficult.
#4 The appearances of beings of light, angels, and gods in near death experiences is proof of . . . absolutely nothing. Would you claim that since God appeared to you in a dream, then He has to be real! If you did, would anyone take you seriously?
So, are “beings of light, angels, and gods” real? I don’t know, maybe. But the probability is small.
