First one happened when I was 12 or 13 years old. We were at the beach, one that is known for its notorious waves but almost never sea currents. This day sea was particularly brave so my brother (two years younger than me) and I were told to not go further than a few steps in. We were happily playing with the waves and I guess we slowly moved further and further into the sea, to a point where we got caught for some moderate sea current that just were too much for us. We shouted as we were getting pulled deeper and deeper and my father came to get us but waves and the current were too strong, so he had to pick one of us and he obviously got my brother. By the time he left him at the sand I was really far in lol, fucking fighting with the waves trying to use them to get me to the sand but the current was just overwhelming and I could barely keep breathing while getting owned, drinking what I thought was half of the sea. I got pulled into some rocks and thought I was done, so frustrated I could do nothing to get out of there and pretty much annoyed that was going to be it, but not really afraid. I guess it wouldnt have been a horrible death anyway. Some gentleman I didnt know and my father got there and after a lot of fighting with current and waves and rocks they were able to pull me out of that hell, but it took them at least 5-6 minutes as I was completely exhausted and although I didnt want to give up I couldnt help them at all.
Second one was really, really stupid. I was out with some friends, drinking beers, most likely discussing some really deep topics, and some really silly ones. Saving the world. Anyway, after a couple hours one of my friends got sick and started puking. Another friend and I decided it was a nice idea to explore an inhabited and long time abandoned building that was pretty close to where we were drinking. So, while the other guy recovered, we left him and another friend babysitting him and went there. Jumped the fence, got there, started fooling around. There was nothing interesting so we decided to go up some concrete stairs to the third level. What was our surprise when over half way up we feel the stairs shake and start bending, slowly, doing some strong sound as if a big water tank was blowing out. I was like "fuuuuuuuck". We obviously stopped moving and it seemed to get stable and stop. We talked to each other, recognizing what was going on. Decided one of us would stay there and the other would start going back down, so we kinda distributed the weight. Keep in mind we were fairly drunk and the situations was really unexpected. He turned and hadnt gone two steps down when the concrete stair fucking collapsed and we both fell down from almost a third floor and onto the ground. I remember feeling the butterflies in my belly and thinking ("a tomar por culo todo" which should be something like "fuck it all" for you). Couples secs later felt a huge hit and my whole body getting smashed by the steps that fell down with us and cut by a lot of rocks and shit that was on the ground floor. However I could get up and check my friend was also ok. We were really lucky as not only we didnt die or got our head or back fucked by those concrete rungs, but we could get up and get the fuck out surprisingly fast with all the adrenaline, without knowing how we had made it with just cuts and injuries all around the body but nothing broken or really serious. What hurted the most was getting the smalls rocks out of the leg, arms, etc... skin and healing it, but yeah.
Last one was this last summer. I was out with several friends and cousins, had been drinking as well, but not much, yet. We were moving to a different pub or disco, I dont remember the specifics of the move. Anyway, I was walking a little behind the group. Most of them were at the other side of the street, and I was 1/3 through the pedestrian crossing when I notice a car is coming really fast to me, in the wrong direction. I wasnt expecting it so barely saw it coming. As I said I felt a lot of vertigo as it was getting terribly fast to me, jumped to try and evade it, and it seemed as if the driver wanted to get me because the car turned to me and I got caught. I remember before being hit and while I was trying to get out of its way I thought it was some douches from which I had had to defend my cousin and get into a fight the Friday before. I almost evaded it, only barely got hit, but wow. The strenght of the hit was overwhelming, I got thrown to the air to take some flying lessons and score the ground aparently about 18-20 feet away. Luckily again, nothing broken (well, 3 teeth were partially broken ; ; ), but got some wounds that pretty much killed the rest of the summer as most of them took over a month to heal. Driver was a guy that was really drunk and probably stoned and drugged to all hell. He didnt stop to see what happened and assist, but rather escaped. Sadly for him, police found him not too far away (as it is just a 8000 people village, not very big at all), in the port, crying and probably wondering about what he just did or where to hide or something, idk. Aparently he was about to be acepted in the police so he fucked up his career at the very least, he may be in prison though, as they are starting to get really serious about traffic accidents while being drunk here in Spain. I still havent gotten any compensation as the case is still being worked on the courts.
Will have to excuse my poor English as it isnt my first language :/
