The lullaby belongs to the Huntress, a killer in the asymmetrical horror game Dead by Daylight, where her humming warns survivors that she is nearby. Players first heard the tune as part of her in-game presence, and clips of it spread through gameplay videos, streams, and short-form edits that used the innocent melody to heighten suspense. Its popularity endures because the sound is instantly recognisable to horror fans, even without any visuals, and it signals danger in a way that is quieter and more unsettling than a scream.
