I'll share one. 'I woke up in the middle of the night. There was a figure at the foot of my bed. When I turned on the light, it disappeared.'
One sentence scary story: The old doll in the attic turned its head as I walked by. It was always facing the wall before.
One: I heard a knock on the door at midnight. I opened it, but no one was there, yet I felt a cold hand on my shoulder.
One: The old house stood alone. Its windows were like empty eyes. I heard a moan from inside. I never went near it again.
I woke up in the middle of the night, and there was a shadowy figure standing at the foot of my bed, just staring at me. It disappeared when I blinked.
One: I woke up in the middle of the night. The room was pitch - black. A cold hand touched my face. I heard a whisper 'leave'. Then I saw a shadow disappear.
Here's another: 'She walked down the empty alley. A shadowy figure began to follow her silently.'
Maybe there is a story like 'The cemetery gate swung open. A cold hand reached out from the darkness.' This kind of two - sentence story quickly creates a spooky atmosphere. It gives just enough details to make your imagination run wild. For example, when you think about the cold hand reaching out from the cemetery darkness, you can start to picture all kinds of terrifying things, like a ghost or some undead creature.
One: The old house was silent. Then I heard a child's giggle and saw a shadow that wasn't mine. Two: I woke in the dark. A cold hand touched my face and a voice whispered 'you're not alone' in my ear.
I woke up in the middle of the night to see a shadowy figure standing at the foot of my bed. It just stared at me with empty eyes.
Some other scary two - sentence stories could be. 'The cemetery at midnight was still. But then the tombstones started to tremble.' 'I was alone in the old library. Suddenly, a book flew off the shelf and landed at my feet.'
