What are some good examples of the opening line of a horror stories?

Well, here's an example. 'The attic was silent. I climbed the ladder, and a cold hand grabbed my ankle.' Also, 'The mirror was fogged. I wiped it, and a face that wasn't mine stared back.' These two - line horror stories create a sense of dread in just a few words. They rely on setting up a spooky situation quickly and leaving the reader to imagine the worst. For instance, in the first one, being trapped in an old house with no way out is a classic horror trope. And in the second, the unknown entity in the attic adds an element of mystery and fear.

Here's another: 'The old doll sat on the shelf. Its eyes followed me. I turned off the light. In the dark, it giggled softly.'

The old house creaked. I heard a whisper. Then a cold hand touched my shoulder.

I opened the basement door. A hand reached out from the darkness and grabbed my ankle.

I woke up to a cold hand on my face. It wasn't mine.

By creating a sense of mystery. For example, 'The door to the attic creaked open, and a strange smell wafted out.'

Lights out. Strange noises. Then silence.

Walking in the forest, I felt watched. I looked up, and a pair of red eyes stared from the trees. It was no animal. There was an intelligence in those eyes that sent a shiver down my spine. I tried to run, but my feet felt like they were stuck in the mud. As I struggled, I could hear the thing getting closer, branches snapping under its weight. I knew that whatever it was, it was coming for me, and there was little I could do to escape.

One that stands out is 'I heard a child laughing in the empty school at night.' Empty schools at night are already spooky places, and the sound of a child's laughter when there should be no children there adds to the horror. It makes you think about the possible reasons for the laughter. Is it a ghost of a child who met an untimely end? Or is it something even more sinister?

I woke up to find a strange handprint on the window beside my bed.
