For the last few nights, he has seen a black blur racing past the window, and sometimes the object would go straight up to the door, and stand there do a while.
As that happened, he could see a face start to appear on it.
It started with the eyes, which made him wonder where he had seen that face before.
A week passed, and while he was going to bed, he saw his door locked, and when he looked in, he could see himself laying there in the bed.
Then he decided to run past the door, and run to a mirror, but it wasn't him in the reflection.
It was the mangled face that he saw in the window.
