I saw this asked on another instance, thought I’d ask it here and I’ll post my response from there in the comments as I think it felt cathartic.
Doesn’t need to be a life or death situation, just any moment in your life where you found yourself saying “Holy shit, I can’t believe this is happening!”
I was at a bar in Mexico for 4th of July when, due to a combination of alcohol, no situational awareness, and a strong sense of bodily autonomy, I accidentally started a riot of about 400 Americans, all college students and Hell’s Angels. The entire scene was scary-crazy. I ended up speed-crawling under the legs of dozens of bikers who were trying to grab me, and escaped into the night.
