A maze area found in the Underwater area.
It has lots of strange patterns, markings and such things on the walls and floor.
- Nexus > Ghost Garden > Underwater (go up) > Underwater Temple
- Nexus > Pipes and Phone Poles World > Apartments (take the elevator) > Dark Corridors > Underwater Temple
- Before the door to the Dark Corridors there is a "print" of Sabitsuki on the wall.
- There is a Uboa marking in a dead end room.
- Several markings resemble the Hovering Screens.
- If a Kaibutsu teleports you to an inescapable part of the temple, the music is slower, making it more ominous and creepier.
- The music resembles footsteps and a breath.
- The Uboa may imply Sabitsuki may have some connection with Madotsuki, the main protagonist in the original Yume Nikki, or rather possibly furthering the theory that Madotsuki is a psychic and is able to enter another's dreams, and may have drawn that in Sabitsuki's dream, of course the game is fanmade so that can only be from fan speculation
