The clip comes from LSD Dream Emulator, a surreal first-person exploration game released for PlayStation in Japan in 1998, where players wander dream worlds without clear goals. Happy Town is one of its stark, sparsely populated areas, and its quiet footsteps fit the game's lonely atmosphere. As clips from the game spread through Let's Plays, horror compilations and soundboards, fans began isolating its ambient noises for their own edits. It remains popular because the sound instantly signals a dreamlike, slightly uncanny walk, even without any visuals from the game itself.
