I have sort of a morbid memory from preschool. I have no idea how old I was because I don't have any children so I don't know when people put their pixie stick puffers in preschool. The memory is kind of vague and I'm actually not sure if it was a dream or not. Any who, this preschool was run out of a church, that is on my block, and was eventually shut down for not being up to code (Nothing serious, I just don't think the kitchen set up was standard). I was out on the playground they had set up, which even from later memories was kind of shabby, and somehow I had managed to score a ladder of some kind. I can't remember it well so I'm not really sure, but it might have been one of those small plastic slides you can buy for young kids or maybe even a metal slide. I'd dragged it (or maybe some other kid) over to the swing set. The swing set was pretty standard and would have had just two swings on it if one wasn't broken, the thing was past it's prime and was an attractive mix of faded yellow and rust. The height of the sladder (slide/ladder) might have allowed me to climb on to the the small bar that held the two support bars of the swing together. I can't remember if I did this or if I simply just had the height I needed from just my trusty sladder. But on the bar, where the swings hang from, was a hook which was left unused due to the swing being gone or broken. I somehow managed to hang myself from it with the back of the collar of my shirt. After doing this I would simply lift my legs out from under me. I remember seeing colors and feeling light headed. I did this a few times and remember enjoying myself. It was all going fine and dandy, I would lift my feet and when I felt like I needed to I would just put them back down on the sladder below me. My system was fool proof. Then I kicked somehow managed to kick the sladder out from under me. I remember panicking and kicking my feet around, just sheer terror. I don't remember if I called for help or not. But even at that age I knew I'd royally fucked myself in the ass with a bee hive. And my trusty sladder just lay there on the ground when I needed it most! I mean, IT REALLY LEFT ME HANGING!

(You can think that's not funny but if you do I hate you and you're wrong)

I remember that the edges of my vision started to blacken a bit. Then I just came crashing to the pebbles on the ground bellow. The collar of my shirt had ripped. All I remember after that is that I was just kind of shaky and in a state of shock. I didn't tell anybody and I'm not even sure if I've ever brought it up. I don't remember anybody being around. And I'm unsure if there were other children or not. As a kid I had a tendency to get into trouble, so it's a possibility that hobbit me was stupid enough to nearly hang myself, and I remember it feeling real. But like I said I actually have no idea if this happened. It's something I'd nearly forgotten about until I was reading through this thread. I'm in college now so it was a bit ago for sure. I'll probably never know.

TL;DR: In preschool I might have nearly killed myself by practicing for autoerotic asphyxia while all the adults weren't looking.
