Can you share some examples of 'two sentence horror story'?

I woke up to find a strange handprint on my window. Then I realized I live on the 13th floor.

One example is 'My sister said she saw mom in the basement. Mom died last year.' It's horrifying because seeing a dead relative in a place like the basement is really spooky.

I woke up to find a handprint on the window that wasn't mine. It was small, like a child's, but I live alone.

I opened the old attic door. A cold hand grabbed my wrist from the darkness.

Example 1: I heard a noise downstairs. When I checked, there was no one there, but the front door was wide open. Example 2: She woke up in the middle of the night. A dark figure was standing at the foot of her bed.

I heard a knock on the door at midnight. When I opened it, no one was there, but I felt a cold hand on my shoulder.

Here's another: 'The old doll in the corner blinked. I was alone in the room.' This is creepy because dolls are often associated with unease, and the idea of it blinking when no one else is around is quite terrifying. It plays on our fear of the inanimate coming to life.

One example could be 'I found an old doll in the attic. Its eyes follow me everywhere.'

Well, here's one: 'I woke up to a strange noise. When I turned on the light, no one was there.'

One example could be: 'I woke up to a cold hand on my shoulder. In the mirror, I saw no one behind me.'
