Yume Nikki is a surreal exploration game released in 2004 by Japanese developer Kikiyama and made with RPG Maker 2003. Players guide Madotsuki through interconnected dreams, searching for 24 Effects that change her appearance and abilities, from a bicycle to a knife. The game built a devoted cult following through free distribution, fan wikis and later releases on Steam, inspiring countless fan games. Its minimal sound design, including this short collection cue, became instantly recognisable to players and is now reused far beyond the game in dreamcore and retro horror edits.
