This kind of creak-and-flicker effect has lived in stock sound libraries for years, where creators grab it for anything that needs instant spookiness without a soundtrack. It spread through short-form horror edits and Halloween compilations, where a ten-second clip is long enough to stage a mini scare. Because the sound needs no context to feel creepy, it keeps resurfacing each October and in year-round ghost-hunting and prank content, doing the same simple job it always has.
