Not too exciting, but..
A good while ago I was walking along a road, just minding my own business. It'd been a pretty busy day after my girlfriend had just kinda ... dropped our relationship, it was all I could really think about. Walking across the road, this car almost hit me - in the moment it was about to I practically leaped out of the way, god knows how I leaped that distance in less than a second. It was going so fast that I almost fell backwards when it passed!
EDIT: Another time was when I was sick, like really sick - I was drowsy and lacked all focus. I'd stayed the night at a friend's house without my antihistamine and had developed some kind of flu by the morning. It was all just too much and I was asleep for most of the trip back home, then when I got into bed I could barely move. Body was heavy, eyes felt sewn shut, pretty much the moment I stopped thinking about things I'd fall asleep and, usually, be treated to some nightmares. Fuck I was scared, barely had anything to eat that day, but the next day I was ... pretty much fine. 0.o'
Also, in a recent trip to Bali I was plugging my laptop into a power point adapter. The damn thing was actually on so, when I plugged it in, bright blue sparks danced around the metal and I, holding the point by the end, right next to said metal and at the end of the plastic, practically shat myself when I realised I could've just gotten electrocuted. Especially considering how I'm usually so careful when it comes to that kind of stuff. D:
