Yesterday, I was so tired, I went asleep at 19 00 just to wake up 3hours later by my phone.. I turn it off and try to fall back to sleep, after a while I was lying thinking of battlefield as the nerd I am.. But all of a sudden the whole room started to move, I heard gunshots and rockets exploding around me. I was litterly sitting in a helicopter. After about 2minutes I was starting to feel numb, just a second after this feeling I entered a sp, it did just fine until I couldn't breathe, I was grasping for air, and it felt like someone really choked me. How do you keep calm trough something like that??
