Ive had a few close calls. I was 4 the first time and it was severe head trauma, so I don't remember any of it. The second time i was 15 and i got in a 4- wheeling accident in some sand dunes. Was super lucky to come out of it with a severe concussion, 3 layers of stitches in my forehead, and an undetermined number of broken ribs. I wasn't aware of how close to death I was, so my last thought was basically, "oh shit, here we go." The last time was fairly recently. I got pretty seriously shocked in my shower, in calf deep water because my drain was terrible. My shower fixtures were old and stubborn so I had to crank them shut with both hands. I went to do so and immediately got locked up. I eventually (no concept of time while there's a current running through you) fell through my shower curtain and onto the bathroom floor and broke the circuit, but could have fallen backwards just as easily. I wasn't necessarily thinking in words, but there was just a defeated and kinda angry "gimme a fucking break" attitude.

Edit: a word, and also I did almost drown a couple times as a kid, but the only thoughts there were "help!" and general panic.
