While I was sleeping I saw an entity in my room.
This entity was just evil, had a dark energy and everything about it was negative and bad.
In my bedroom, there was a furniture located opposite my bed and against the wall. That entity was sitting in the right corner of the wall on a cabinet. I can't say if the word 'sitting' is the right word because this being had very, but very short legs...so, it's possible that it's standing looks like sitting, with it's knees a bit bent. He was small, maybe it's whole body with knees bend was not more than half a meter long. It's legs and arms had animal claws. It's face was not human, but it didn't look like animal also... It was more like a distorted humanoid face. And it had horns.
It was watching me for a short period and then I noticed it held something in it's hand. It threw this item on the floor, in front of my bed. I don't know what that item exactly was, it sounded like throwing a stone on the floor.
In that moment I woke up and started screaming very loud, my screaming woke up people in the house. My behavior was strange even to me because I don't usually react that way.
Few days later I learned that I was sick and I had to undergo some operation, which was harmless. In the end, everything was ok with that.
Several years later I came across (saw on the internet) a book called "Codex Gigas" or "Devil's Bible" and there was a picture of a devil. It looked very similar to the entity I saw in my room that night. The creature in the book wears diaper, that's the only thing I can't recall if that evil entity in my room worn.
