Here is another. 'The little monster hid under my bed. Every night, it whispered my name in the dark.' This simple two - sentence horror story creates an immediate sense of unease. Just the idea of a hidden presence under the bed that knows your name is quite terrifying. It plays on our common fear of the unknown in the dark, and the fact that our own personal space, like our beds which are supposed to be safe, can be invaded by something so menacing.
One more could be 'A little monster followed me home. Now it's in my closet, waiting.' This short horror story quickly builds tension. The thought of being unknowingly followed and then having the pursuer end up in a place as close as your closet is very spooky. It makes you wonder what will happen when the closet door opens.
