Can you share some of the scariest two - sentence horror stories?

I saw a figure at the end of the hall. As I blinked, it vanished, leaving only a chill.

Well, there's 'My daughter won't stop crying and screaming in the middle of the night. I visited her grave yesterday.' Also, 'I heard a noise from the basement. The power has been out for days so it couldn't be the furnace.'

I woke up to the sound of scratching at my window. When I opened my eyes, a shadowy figure was peering in.

Sure. 'I found a doll in the attic. At night, it moved on its own.' Dolls are often creepy, and the thought of one moving by itself at night is really scary.

Another really scary one could be 'My phone rang at 3 am. The caller ID said it was me.' It plays on the idea of the self being something other or unknown, and calls at that time are always spooky.

Here is one. 'The old house was silent. Then I heard a voice whispering my name from the attic.'

Another horror two - sentence story is 'I walked into the basement. The moment I turned on the light, I saw a figure with no face disappearing into the shadows.' The lack of a face is very creepy and the fact that it disappears into the shadows as soon as the light is on adds to the horror, leaving the reader to wonder what that figure was and what it might do next.

I woke up in the middle of the night to a strange noise. When I turned on the light, there was a shadowy figure at the foot of my bed.

Story 1: I woke up to a cold hand on my face. When I turned on the light, no one was there.

I think 'The clock stopped at midnight. Then I heard footsteps.' is quite scary. It gives this feeling of something ominous starting right at a spooky time.
