I don't buy the "copy" scenario, and I'll tell you why. There's an experience aspect in NDEs where a person is on the operating table - and "dies." This individual is in the room as spirit, usually hovering over the table, watching everything that goes on. When the body is resuscitated this "spirit" goes back into the body. Later, they have a discussion with the doctors regarding everything they "saw" - and it's all verified.
Not exactly. Do a search for the AWARE Study. When you really dig into it, there has been no "verification" by the experiments specifically done to scientifically gather substantial evidence. I'm referring to those experiments in which a target message was hidden up and out of sight of operating room patients, unless they could actually float-up out their body and see it. ZERO patients have correctly identified a target.
Then there's a professor in the UK who was part of a study group there ( the name escapes me now ), but I heard her describe during an interview how she proved to herself that her OOBEs cannot be counted on precisely because despite being completely photorealistic, she learned that her perceptions din't correspond with the actual state of affairs at the time.
Virtually ALL the best evidence points at a functioning brain as the cause of our perceptions.
So ... what went "back into the body?" A "copy?"
The assumption there is that there actually was something that went "back into the body". The more probable situation is that there was no "thing" that was "out there" in the first place. It is a vivid lifelike illusion with a few interesting anomalies that are explainable other ways.
Whatever this "spirit" is, it's part of the physical construct. It was there at the time of conception, in both sperm and egg, because these component parts were "built" by the mother and father's bodies, where this "spirit" aspect is just part of everything that goes on.
That all depends on what EXACTLY one means by the word "spirit". To me it's indistinguishable from "personality". You can say a person is a "kind spirit" or has a "kind personality". There's no difference, and there's zero evidence that there's some ethereal form that carries the personality with it away from the body when it kicks the bucket. Personality has been scientifically proven to be brain dependent.
The bottom line for me is that every cell in our body has this "spirit" aspect as part of the overall picture, and just like the physical body functions as it does, and the brain functions as it does, this "spiritual" component is a cell by cell build of the original. This is why it functions as it does, and the "bad spirits" are just like they were in their physical life because it's them.
That all sounds rather like Midi-chlorians or other fictional or mythical things.
Midi-chlorians were intelligent microscopic life-forms that lived symbiotically inside the cells of all living things. When present in sufficient numbers, they could allow their host to detect the pervasive energy field known as the Force. Midi-chlorian counts were linked to potential in the...

This wouldn't be a "copy" ... it would be a component part continuation of the original build.
What wouldn't be a copy? The totally unproven and rather impossible "spirit molecules"? Sorry if I come across as dismissive, but all the best evidence points to "spirit" being the same as "personality" which is a product of brain function. Take away the brain, and you get zero personality. Change part of the brain and it changes personality, sometimes radically. There's no escaping this.
Therefore if this afterlife "spirit" has any personality, then it must be caused by something that has taken over the function of their now deceased brain, which once again results in a copy. The only true continuity of personhood is actual immortality where you literally never die, not some ethereal partially there remnant of ones former self that is more like a projection than a living being.
Again, sorry if this is disturbing. It can make some people upset to hear there's cannot be any postmortem la la land. It's not a matter of because we haven't died and gone there we can't say. We can logically
deduce ahead of time that it's just not
possible, and therefore the phenomena reported must be something other than what afterlife believers think it is.
