What are some good two - sentence horror stories?

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.

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

Walking in the forest, I saw a pair of glowing eyes. Before I could run, a growl echoed around me.

The clock stopped at midnight. Then, I saw a shadow figure pass in front of it.

How about this: 'I heard footsteps behind me. When I turned around, there was no one there, but the footsteps grew louder.'

Yes, it can be. They're short and intense, giving a quick scare.

The old doll's eyes followed me. Then it whispered my name.

I woke up to a strange noise. When I opened my eyes, a shadowy figure was standing at the foot of my bed.

I walked into the empty room. Suddenly, I felt a cold hand on my shoulder, but no one was there.

One example could be 'I woke up to find a cold hand on my shoulder. I live alone.' Another is 'The old doll in the attic blinked. It was facing the wall before.'
