Here's another: 'The old doll stared at me. Then it blinked.' This is a simple yet creepy example from such horror stories. The first sentence sets a somewhat normal but eerie scene with an old doll just staring. The second sentence, where it blinks, takes it to a whole new level of horror as dolls are not supposed to blink. It plays on our expectations of inanimate objects and violates that in a very spooky way.
One could be 'I woke up to a cold hand on my shoulder. It was my own, severed in my sleep.'
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.'
I woke up to a strange noise. When I looked under the bed, I saw a pair of eyes staring back at me.
Here's another: 'I saw my reflection smile at me. I wasn't smiling.'
One example could be: 'I woke up in the middle of the night. There was a figure standing at the foot of my bed with no face.'
One example could be: 'I woke up to a cold hand on my shoulder. In the mirror, I saw no one behind me.'
Another is 'The old house was silent. Then I heard the sound of a rocking chair moving on its own.' Here, the first sentence sets a spooky scene of an old, quiet house. The second sentence adds the horror element by introducing an unexplained and creepy sound of a rocking chair moving without anyone seemingly around to move it.
The clock stopped ticking. Then I heard the echo of a heartbeat that wasn't mine.
Story 1: I woke up to a cold hand on my face. When I turned on the light, no one was there.
One example could be 'I heard a scratching at my window. When I opened the curtain, there was a faceless figure.' Another is 'The old house was silent. Then I saw a pair of glowing eyes in the dark corner.'
I heard a baby crying in the attic. I live in an apartment. This is funny horror as it quickly sets up a spooky and illogical situation.
