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.'
Story 1: I woke up to a cold hand on my face. When I turned on the light, no one was there.
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.
The first one: I woke up in the middle of the night. When I looked at the mirror, there was a face that wasn't mine.
She checked under her bed. A pair of eyes stared back.
One: I woke up in the middle of the night. The figure at the foot of my bed was my own corpse.
I heard a baby crying in the attic. When I went up, I saw my old doll with a knife in its hand.
Here's another: 'The old doll in the attic blinked. I ran out and never went back.' This creates a sense of unease with the simple and unexpected actions. The blinking of the doll, which is an inanimate object, is very creepy.
One story could be: 'I woke up to a strange noise in the attic. When I went to check, a pair of glowing eyes stared back at me.'
