I have 3 instances of major andrenaline rushes in my life, and because I could not decide which one to choose, I just dump them all here in the happening order.
while I were pretty young, my uncle owned micro car with those open motors where you can see all the moving parts like cogwheels and chains, and being stupid little boy I went and shoved my finger between 2 cogwheels when shit were running.
It did not help anything that we lived in the most seculed location and I had to wait 2 hours for ambulance, then another 2 to get to hospital, while cradling my hand when it were bleeding like pig in slaughterhouse. Now i'm half of finger short.
(For second instance, I propably should mention that I have slight case of snake phobia, nothing too big, I just utterly flip my shit when I see snakes that are not behind cases or something.)
When I were couple of years older, we decided to visit some known nature-themed locations in northern finland, including "hiidenkirnu", "kummakivi" and very old "settlement" of cabins, that were localy called as "The town of crazy man"
(for those interested in the story, it is group of 9 cabins, all build by only one man, and only one of those were used by the owner himself and rest were never used)
now when we were leaving it, while I were in mid-step, this one non-venomous viper decides to try EAT MY FUCKING FACE, so being the very definition of calm myself, I jumped backwards 4 meters, with one leg and while still going in forward momentum, and after that the thing decides to FOLLOW ME, so being too scared to even turn around, I ran backwards faster than I ever did.
luckily I survived.
3rd: You know that thing when you are falling asleep and you suddenly jerk fully awake?
that thing which is most likely followed with sudden muscle tension or swinging arms?
yeah, those are not so fun for us with insomnia, because we sometimes manage to go even deeper relaxation before falling asleep.
in my worst case, I had been awake for some time already, maybe around 30-40 hours, and were in desperate need for sleep, so I did all the tricks: tea, intense workout hours before time, being unactive for hour before sleep etc.
and were pretty close to fall asleep. Then it happened.
I kicked my legs out, broke my alarmclock and hit my head into wall, and my heart kept pounding like no tomorrow. I did not get my sleep that night.
