I saw a face in the window. It vanished when I blinked.
Of course. Here are two. 'The phone rang in the dead of night. A raspy voice said my name.' and 'I opened the closet. A pair of glowing eyes peered out.' This type of two - sentence horror stories are effective because they create a sense of immediate dread. In the first one, a late - night phone call with an unknown voice saying your name is a classic horror trope. It makes you wonder who is on the other end and what they want. In the second, the idea of something lurking in a closet, which is a common, seemingly safe place in a home, is suddenly made terrifying by the presence of those glowing eyes. It plays on our sense of safety being violated in a very familiar environment.
The old doll in the corner moved. Its eyes followed me as I walked across the room.
I found a doll in the attic. Its eyes seemed to follow me as I left the room.
The mirror showed my reflection smiling. I wasn't smiling.
I took a shower. The water turned to blood and a face formed in the steam.
The bag man came closer. I heard his bag rustle, and fear gripped me.
I found an old photo album. The pictures inside started to change, showing me dead in different ways. I couldn't look away at first, but then I threw it away in horror.
Walking in the forest, I saw a pair of glowing eyes. Before I could run, a growl echoed around me.
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.
Here is one. 'The old house was silent. Then I heard a voice whispering my name from the attic.'
