Loss of consciousness is not death, your brain was alive the entire time. It takes upwards of 10 minutes before the brain dies, usually longer, and each minute approaching those thresholds has a high probability of severe brain damage. Check out cerebral anoxia or brain death to learn more.
If you were expecting actual death, then no revived person has ever experienced death because they weren't completely dead to begin with, even if tissue damage happened. Let's compromise on near death experience.
I’m basing it off of people saying they died, and they didn’t, because like you said, you literally can’t come back from death. What was described was loss of consciousness/passing out, and it’s odd so many people pass out and claim they died.
