Cave ambience sounds like this have become a staple of online horror and gaming content because they instantly signal depth, darkness and isolation without any dialogue. Creators reuse short underground clips for video game builds, urban exploration edits, ASMR-style relaxation tracks and Halloween compilations, where a few seconds of drips and echoes can carry an entire scene. Its simplicity is the appeal: the sound is recognisable, easy to loop or layer, and works just as well behind narration as it does on its own in a quiet, tense moment.
