Perhaps you might want to set up a video camera at night to see what's going on.
Maybe you're being abused while you sleep. I heard this can happen.
Maybe you weren't stabbed, but kicked by your night mare. Wandering why would you sleep in the stable.
You likely harmed yourself while asleep. People do it all the time. It has nothing to do with demons. If something has been bothering you, you probably need to address it.
...don't toy with the dark side.
That was the nightmare, now you can wake up.
Is freddy crugar girl!!
Demons can do physical on you.
