One could be a character looking into a mirror and seeing something behind them that is not visible when they turn around. At the end of the story, they are about to look back again, leaving the reader on edge, wondering what it is that's lurking there.

The silence in the forest was like the calm before a storm of horror. It creates a sense of anticipation, much like when the air is still right before a really bad storm hits.

An underwater cave system. The water is cold and murky, and the caves are full of sharp rocks and tight passages.
