Sinister Scraping Sound

The next moment a hideous, grinding screech, as of some monstrous machine running without oil, burst from the big telescreen at the end of the room. It was a noise that set one's teeth on edge and bristled the hair at the back of one's neck.

—Nineteen Eighty-Four

The Sinister Scraping Sound is the issue of the Unholy Matrimony between Nails on a Blackboard and Audible Sharpness, with Nightmare Fuel acting as the godfather. This is a very basic Horror trope, the sound of metal scraping on metal, rock, wood, or another hard surface. It might be heard continuously or rhythmically, slowly intensifying as the source approaches.

It might be a knife on a countertop, a machete against a pipe, a sword against the ground, or a Chainsaw against basically anything if you want to ramp up the fear. This usually plays hell with hidden characters who are trying to hide, as it increases their panic. If they can keep their mouth shut, they might survive... or get pulled/impaled through the wall. Of course, the noise might be something completely innocuous that leads to another, more dangerous scare.

As the picture shows, it might be accompanied with sparks. Characters arriving after the scraper has left will no doubt wonder at who left the scratches --or gouges—on the wall/floor. The foreboding Bloody Handprints and body parts everywhere will be easier to piece together (unlike the bodies).

Often an example of Hell Is That Noise.
