I just woke up from a bad nightmare.
So in the dream There was this man chasing me. He had been killing everyone and for some reason he started chasing me. But this one girl offered to be killed instead of me. So i trusted her and stayed calm, but then she didn't do it and the killer guy was chasing me again. So I grabbed his knife and brought it down in the middle of my chest.
I shook awake because from the nightmare i felt a deep pain in my chest like the knife was still there.
This really scared me so please help. I'm scared to sleep now.
