I had a nightmare once that started of pretty average then ended horrifyingly: i was playing a video game (like COD) with a friedn inside a huge department store. after a while we walked out of the store into this really dusty courtyard with a low wall along one side. after a few seconds two soldiers came in through one side of the courtyard and my friend dragged me behind the wall. she suddenly had a gun and after telling me to stay where i was, she jumped over the wall and started shooting. I screamed after her to come back because i was unarmed, but when i looked over the wall she was fighting one of the soldiers and the other one was coming straight towards me. i tried to run away, but the second soldier vaulted the wall and pinned me to the ground (i was on my back) he was unarmed, but so was i and i couldn't move. he placed his hand in the middle of my ribcage and started to push inwards. i could feel my bones cracking under the pressure. I panicked and tried to move, but he still had me pinned. I started to balck out becuase i couldn't breathe. a few seconds before i wnet under, i remeber thinking "hey it's okay. you don't have to die. you can sleep" and the moment before i became unconscious, the sodlier finger broke through my skin and i relaised what he ahd been trying to do: break through my ribcage to pullout my heart.
and then i woke up and i freaked out for a few seconds till I ascertained i was, in facte, still alive.
