Can you share some ideas for a very short horror story?

Sure. You could start with a character waking up in a strange, dark place all alone. For example, a young girl wakes up in an abandoned asylum. She hears strange noises like scratching on the walls and faint whispers. Then, as she tries to find a way out, she discovers old patient records that seem to have her name on them, even though she's never been there before.

Sure. One could be about a creaking door in an old house that always opens at midnight by itself, and no one knows what lurks behind it.

Sure. Here's one: The old house was empty for years. I heard a baby crying from inside. I entered, but there was no one. Then I realized the crying was coming from the walls.

There was a story about an old, abandoned asylum. People said at night, strange noises came from it. One night, a curious young man entered. The halls were dark and cold. As he walked, he heard whispers that seemed to be right beside him. Then, out of nowhere, a cold hand grabbed his ankle. He screamed but no one could hear him.

The last person on earth sat alone in a room. Then there was a knock at the door.

One short horror story is about a girl who woke up in the middle of the night to a strange dripping sound. She followed it to the bathroom. As she opened the door, a cold hand grabbed her ankle from the dark bathtub. She screamed but no one heard her.

Imagine a camping trip. A group of friends set up their tents in a seemingly peaceful forest. But at night, they hear strange howls. One by one, they start to see glowing eyes in the darkness. When they try to leave, they find that they are going in circles, as if the forest itself is trapping them. Eventually, they realize that they are being hunted by a pack of werewolves.

A woman woke in the night to see a figure at the foot of her bed. She blinked and it was gone. But then she felt a cold hand on her ankle.

One story is about a girl who moved into a new old house. Every night, she heard strange scratching noises from the attic. One day, she finally went up there and saw a long, bony hand reaching out from a small hole in the wall.

A skeleton walked into a bar and said, 'Give me a beer and a mop.'
