Heres one that scared the living shit out of me when I was younger.
A young boy is sleeping in his bed on a usual night. He hears footsteps outside his door, and peeks out of his eyes to see what is happening. His door swings open quietly to reveal a murderer carrying the corpses of his parents. After silently propping them up on a chair, he writes something on the wall in the blood of the dead bodies. He then hides under the childs bed.
The child is scared beyond belief. He can't read the writing on the wall and he knows the man is under his bed. Like any child, he pretends that he slept through the whole thing and hasn't awoken yet. He lays still as the bodies, quietly hearing the breathes from under his bed.
An hour passes, and his eyes are adjusting more and more to the darkness. He tries to make out the words, but it's a struggle. He gasps when he finally makes out the sentence.
"I know you're awake". He feels something shift underneath his bed.
