So you have doubts about the experiences being real, even the ones where verification has been sought and found for the claims in those experiences.
You still cannot grasp that the only real verification in sciences, are testable and verifiable OBSERVATIONS & DATA, which are either:
A) evidence
B) experiments
...or both, evidence & experiments.
Data include any information from the evidence and experiments, such as detection, quantities, measurements, comparison of evidence.
Anecdotes of OBE are merely stories and claims, which cannot be detected, quantified, measured, compared.
When scientists talk of verification, they are talking about being able to test hypotheses or scientific theories. And tests can only come from evidence or experiments (or both). How many times must I say that before you get in your head, that OBE have never been verified, as there are no evidence?
I don't deny people who have been near-dead or been clinically dead, and reviving. What I find doubtful of, are stories of floating consciousness or spirits.
A person who suffer from oxygen starvation, do hallucinate. And the same would be people in NDE where the brains are not getting oxygen, because the blood are circulating.
Plus, you are forgetting there have been number of people who revived after being clinically dead, and seen nothing.
Do you only accept people with stories of OBE, and ignored those who have no such experienced when they were dead?
If you ignored those who experienced no such visions, then you are cherry-picking only anecdotes that you believe in. That's just simply confirmation bias.
You don't have any physical evidence of OBE, just as you have no evidence of disembodied consciousness or mind. They are merely claims and stories that cannot be verified.
OBE falls under pseudoscience, as it is utterly unfalsifiable, and most important of all, you cannot test these anecdotes.
OBE is no better than anecdotes of alien abductions. It's flimsy and it's absurd, and it is something that you cannot test.
