Here is one: 'The old house was silent. Then I heard a child's laughter that wasn't there before. It sent chills down my spine.'
Another one could be 'I looked in the mirror and saw a face that wasn't mine. When I turned around, no one was there.'
The first one: I heard a strange noise outside my window. I peeked through the curtain and saw my own reflection with a sinister grin. Another one: I woke up in a cold sweat. There was a figure at the foot of my bed, but when I blinked, it disappeared.

Well, 'I was walking alone at night. A figure emerged from the shadows and whispered my name in a raspy voice.'
Sure. Here's one: I woke up to a strange noise. When I turned on the light, a shadowy figure was standing at the foot of my bed.
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.
Sure. Here's one: I woke up in the middle of the night. My reflection in the mirror was smiling while I wasn't.
Here is one. 'The old house was silent. Then I heard the sound of a child laughing from an empty room.' This simple two - sentence horror story creates a spooky atmosphere. Just imagine being in a quiet, old house and suddenly hearing a child's laughter from a room that's supposed to be empty. It gives you a sense of unease and mystery.
Here is one. 'The old house was silent. Then I heard a voice whispering my name from the attic.'
I once read one. 'The old man sat alone in the dark room. Then he realized he was not alone.'
I opened the old book at teatime. The pages whispered my name in a voice that wasn't there.
