Can you share some very short horror stories?

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.

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

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.

One idea could be a person walking alone in a forest at night. They hear strange whispers all around them. As they look around, they see pairs of eyes in the darkness. But when they shine their flashlight, there's nothing there.

There's 'The Monkey's Paw' which is a great horror very short story. It involves a family who comes into possession of a magical monkey's paw that can grant wishes, but each wish comes with a horrible price. Also, 'The Yellow Wallpaper' by Charlotte Perkins Gilman can be considered. It's about a woman's descent into madness while being confined in a room with yellow wallpaper.

One very horror short story is 'The Tell - Tale Heart' by Edgar Allan Poe. It's about a narrator who is haunted by an old man's vulture - like eye and eventually kills him. The guilt drives the narrator to madness as he imagines he can still hear the old man's heart beating even after the murder. Another is 'The Monkey's Paw'. A family gets a magical paw that grants wishes, but each wish comes with a horrible and unforeseen consequence. The third one could be 'The Yellow Wallpaper'. It shows a woman's descent into insanity due to her confinement and the strange patterns on the wallpaper.

One of the short horror stories could involve a forest. A hiker gets lost in a dense forest. As night falls, he notices eyes watching him from the bushes. He tries to run but feels like something is always just behind him, chasing him through the never - ending forest.

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.

Sure. Here is one. A magician was walking down the street and turned into a grocery store.
