The little girl found a doll in the forest. As she picked it up, the doll's eyes started to bleed.
Sara looked into the mirror. But instead of her reflection, she saw a shadowy figure slowly approaching her from behind the mirror.
Well, start with a scary setting or a mysterious character. Like, 'The old house creaked. A shadow moved behind the curtains.' Make it short and spine-chilling. Also, use simple but powerful words to build tension quickly.
Think of a common fear and describe it in an unusual way. Say, 'The mirror showed my reflection. But it wasn't mine.' Keep it short and intense.
The phone rang at midnight. When I answered, all I heard was heavy breathing and then a whisper of my name from an unknown voice.
The moon was full. But the werewolf outside my window wasn't howling at it, but rather staring right at me.
Think of a common, ordinary situation first. For example, 'I was walking my dog at night.' Then add a terrifying twist like 'Suddenly, the dog started growling at me, and I realized there was something following us that only the dog could sense.'
Sarah walked down the dark alley. Out of the darkness, a pair of glowing eyes stared at her, and she knew she was being hunted.
One way is to set a spooky scene in the first sentence, like 'The graveyard was covered in fog at midnight.' Then, introduce a terrifying element in the second, such as 'Out of the fog, a pale hand reached for me.'
He looked in the mirror. His reflection had a sinister smile that he didn't have.
The forest was thick and dark. I felt like I was being followed. A howl echoed and something grabbed my ankle.
Well, it's about the unexpected. In a 'two sentence horror story' like 'I heard a knock at the door. When I opened it, there was nothing but darkness.' The suddenness and the unknown in just two sentences can send shivers down your spine.
