A child was home alone when the power went out. He lit a candle. In the flickering light, he saw a shadow on the wall that didn't match his own. It grew bigger and bigger. He ran to his room and hid under the bed. The shadow seemed to follow him. He closed his eyes and prayed until his parents came home.
Sure. For example, a story where a vampire is allergic to blood. Instead of being a fearsome predator, he has to find alternative ways to get energy and ends up befriending the local baker to get some special energy - rich pastries. It's a comical take on the usually scary vampire concept.
Abandoned house. Whisper. Sudden chill.
Dark Room. Just two words but it can be really scary as it makes you think of the unknown terrors that might lurk in a dark room.
Sure. There was a story about a doll. It sat in an old attic. Every night, its eyes seemed to follow the moonlight. One night, a girl heard it giggle. She ran, but the giggle got closer. In the end, she saw the doll at her bedside, smiling wickedly.
An underwater cave system. The water is cold and murky, and the caves are full of sharp rocks and tight passages. There could be strange, bioluminescent creatures lurking in the depths, and the pressure of the water above adds to the sense of danger. If you get lost in there, there's a real fear of never finding your way out.
Silence. When there is complete silence, it can be quite scary. There could be a sense that something is about to happen, like in a horror movie before the big scare. It gives an uneasy feeling as if the world has stopped and danger is approaching without any warning.
