Unfortunately I have had way to many ,most due to my own negligence. One that comes to mind is when I was in Hawaii and made the mistake of swimming in a turbulent inlet and was actually sucked into an underground tunnel and trapped . I was surrounded by solid rock and held my breath as long as I could when suddenly the action of an incoming or out going wave caused me to be literally popped out of an adjacent sink hole

Yes. Twice. Most recent one last year in a surgery gone sour. The experience is still fairly vivid. First one was not diagnosed and I can't really say it was a result of an actual death with any honesty. My memories of the first one are not clear at all. I am assuming you meant NDE and not just life threatening close calls. If the latter, I have a book full of them.

My first was when i was coming home from school one day. I thought i had looked all around before i crossed the road to get to my house. I walked to the center of the road and for some reason i stopped. An 18 wheeler zoomed pass me on the other side of the road. It was fast. I could feel the vacuum try to pull at me after it passed. Thats the first i remember.
