This clip comes from Phasmophobia, the co-op ghost-hunting game released in 2020. Players widely recognize the singing as part of the game's unsettling ghost events, and many searches ask which ghost sings, even though the sound is mainly treated online as a general spooky cue rather than a confirmed single-ghost signature. It spread through gameplay videos, TikTok horror edits, and streamer highlights because the quiet singing creates dread before a hunt or scare. That contrast keeps it useful in horror memes and gaming compilations.
