A 'bad two - sentance horror story' could be 'I saw a figure in my room. When I turned on the light, it disappeared but left a cold spot.' Also, 'The phone rang in the dead of night. When I answered, all I heard was my own scream.'

These stories create a strong sense of horror in two sentences by leaving a lot to the imagination. Take 'The doll on the shelf had its eyes closed. Now it's staring at me.' It gives you just enough information to be scared but not so much that it over - explains. The reader's mind fills in the gaps with all sorts of terrifying possibilities. It's like a quick jolt to the senses, and our minds are wired to fear the unknown, so these short stories can be very effective at inducing horror.
