Eerie sound effects

Eight unbroken seconds of steel bending in on itself, the pitch drifting the whole way. The version most scenes want, because the drift keeps it from ever settling into something you can ignore.

A cymbal edge dragged with a bow until it rings. High, glassy and steady, it sits in a register nothing else in a mix occupies, so it never fights the dialogue.

Dry wood taking weight in slow stages, with no footfall at either end. Removing the step is the whole trick: the audience supplies a person the recording never contains.

One pure high tone with a faint wobble in it, held steady. Because it is close to a musical note, it reads as intentional, which is unsettling in a way that noise never manages.

Seven drops at uneven intervals, each with a low tail underneath. The unevenness is what makes it work, because a regular drip becomes a metronome and stops being watched.

Brittle clicks arriving in bursts of three and four with nothing joining them up. Thin enough to sit under a voice at low level, where it registers before anyone notices it.
