It is not semantic quibbling because the argument is that the experience of being "near death" allows people to peer through some sort of door and see what death itself is.
I'm not making that argument. I'm pointing out that this phenomenon occurs in many people who are clinically dead, and claiming clinically dead people aren't "near death" is about as silly as the post that started this thread. I don't care what it "allows" people to claim, but the argument that NDE's are a misnomer because they don't happen to people near death is laughable. When someone is in cardiac arrest, and the ambulance is racing to get to them in time, is that because they're near death or not near death?
If I step out in front of a speeding bus I am "near death" too. But that is no more a way of peering into a hypothetical afterlife than having my heart stop for a few minutes.
Someone who's in cardiac arrest is dying. Someone who steps in front of a speeding bus isn't dying. After they get hit by the bus, they may or may not also be dying, but until they get hit, they're as alive as anyone else. Not so when your heart stops.
What people refer to as near-death experiences are typically periods of oxygen deprivation leading to unconscious or severely compromised consciousness.
It's typically when someone's heart stops, and they're not breathing, which is called "clinically dead". If you think someone who is clinically dead and in the middle of whatever dying process you have in mind isn't "near death", I don't know what to tell you.
One can be in these states whether one is next going to die, or as is true of everyone who have spoken of them, is next returned to consciousness. The observations related by people who have been in these states is an accurate telling of what they experienced mentally in that state, but that state itself has no relationship to death or what death itself is like.
We don't know if it's an accurate telling of what they experienced in "that state", because we're still not sure when an NDE happens. Is it before cardiac arrest? In the few seconds after cardiac arrest before brain function flatlines? Minutes after cardiac arrest? After resuscitation? Pinning down the timeframe is where a lot of the research is at.
Also, if "death itself" (i.e., an afterlife) is like an NDE, then your claim that an NDE has no relationship to death itself is false. If, after you die, your existence morphs into something exactly like an NDE, then an NDE would have a strong relationship to death itself. Is that what happens after we die? Who knows.
Yes, they may be "near death" if left untreated, but that is no more relevant than observing that they are also usually physically near a doctor or EMT at the same time- it doesn't provide them any special insight into the personal life of the MD or EMT.
They're "near death" when they're in cardiac arrest, whether they're treated or not. There is no guarantee that treatment is going to bring you back from clinical death. I don't understand your point about "special insight".
