This sound comes from Phasmophobia, the co-op ghost hunting game released by Kinetic Games in 2020. Small in-game audio cues like this became familiar to players through streams, YouTube highlights and TikTok horror edits. The light switch click stays popular because it is instantly readable to fans of the game and useful in short-form editing. Its brevity also makes it easy to drop before a scare, a reveal or an awkward moment in dark, suspenseful scenes.
