You sound like a survivor. Don't know how I know that

Can't vote on this one because none of the answers apply. Looks like the way the answers are structured, I'm expected to be credulous about NDE claims / significance or I'm an idiot.

My answer would be, no I haven't had one, know about them, have examined the evidence and found it wanting as evidence for an afterlife. They are NEAR death experiences, and so convey no info about death anyway. I have rational reasons for that conclusion. I've examine the claims, the science that's been done (they HAVE been studied, even double blind, and results are, at best, when interpreted by people who hope they will prove something, "inconclusive" ).

As to your experiences, I don't think even an NDE proponent would claim they qualify as an NDE. All sorts of weird things happen on drugs / painkillers / chemo, they are all expected side effects of same. My wife's mother, who died of Hodgkin's when my wife was 9, had all sorts of weird symptoms too, which in other circumstances would probably qualify as bipolar with psychotic episodes, but were probably just a combination of meds and physical deterioration (this was the era before anyone was ever cured of Hodgskin's).

My current wife and I are both widowed and used to leave near Chicago, the home base of the guy who invented "induced near death communications". He claims to be able to induce a state in 80% of people who come to him, where they have realistic hallucinations of departed loved ones, and obtain closure thereby. It is sort of a reverse NDE. We thought, what the heck, why not? And went to see him. He worked on both of us for about an hour and got absolutely no result. I guess we belong to the incredulous 20%.
