Yume Nikki is a game consisting of many interconnected locations that vary wildly in theme and size. One of the goals of the game is to visit them all and witness the many events that take place there.
The dream world is an intricate labyrinth of openly looping regions and obscure pathways, but most regions of the game can be considered as part of an individual 'world' with connections to other worlds.
This is a list of all the central worlds of Yume Nikki. Note that in this wiki, the commonly-accepted fan names are used as the regions of the game have no official name.
The Real World Edit
The place Madotsuki starts in, both in the real world and the dream world.
The Original Locations Edit
A place containing doors leading to Madotsuki's Bedroom and the 12 original locations.
One of the most notable areas in the game, some consider the Number World to be the most unsettling. The floor is tiled with numbers, and creatures with a head and two legs plague the area.
It's a neon world. Accompanied by small flashing box-like creatures and odd Aztec neon sign designs in the background in certain rooms, it is arguably one of the hardest areas to navigate.
A world with Shield-Folk inhabiting it. They do nothing. There's a building that leads to an invisible maze here, and near a mass of Shield-Folk there is a floating cat head that gives you the cat effect. Probably the easiest world to navigate in the entire game.
It's a world filled with, yes, candles. There's a dwarf running around near the middle of the world, and if you can manage to catch him you get the "Midget" effect. There's a building that leads to the Tile World with the Lunatic Toriningen. Next to a Toriningen is a bed, and as many know this Toriningen is abnormally fast when made lunatic.
It's a world filled with eyeballs and hands rising from the ground. There's a passage that leads to the Footprint Passage #1 in here, and also, a hand with an eye in it's palm gives you the "Medamaude" effect.
This is a world with floor tiles that make different noises when stepped on. Here is the building that leads to the Mall/Department Store. When the world is looked at from a distance, it forms two Aztec-themed pictures. In this world is the "Bicycle" effect. At the end of the "trail" formed by one of the pictures is the woman's bathroom. This world is also known as the Musical Tile World.
A world with multiple murals. In here you can find the "Blonde Hair" and "Long Hair" effect giving mouth-monsters. Also in this world is the manhole that leads to the Sewers.
A snowy world with areas of trees. Around this world, there is a Yuki-onna (Snow woman) that gives you the "Yuki-onna" effect. There are multiple igloos in this world, one leading to the Pastel Shoal world. There is also a bed in this world.
A world completely dark, where you have to use the "Lamp" effect to see (or you could put the game against a dark background if you're playing in Windowed mode) better. The "knife" effect is located here, and so is the passageway to Wilderness A.
A dark world filled with puddles and lampposts. The "umbrella" effect is located here. Going down two lampposts from the door and going right will lead you to a pink stairwell that takes you to the Dense Woods.
It seems to be based on the common horror element of a dark area with puddles.
A world filled with blocks. There's a men's bathroom located in this world, as is the "Hat and Scarf" effect. If you talk to the Hat-and-scarf girl, she will teleport you somewhere you normally cannot go. Occasionally she'll teleport you to a place with a shortcut to the Monochrome World/White Desert. Talking to her as a snowman will not teleport you to a random place on the return trip. There is a bed in this world.
A Forest area with a part of the Aztec Rave Monkey as the Parallax Background. In this world, you can find a frog that gives you the "frog" effect, and the purple and pink blobs do nothing to you when touched. Somewhere in this world is a passageway to the Face Carpet Plaza.
Also known as the "Red Maze", Hell is one of the largest and most confusing areas in the game, with many branching pathways and Toriningen stalking the narrow paths. There are many connections to other areas, and strange sights to see such as a Vending Machine and a character from the Footprint Path.
Areas where the game's graphics change to resemble an 8-Bit RPG such as Mother or Final Fantasy.
A monochrome land that's one of the most known well places in the game due to the amount of bizarre characters and events that can be seen here.
The Mall is an area that can be accessed from the elevator in the graffiti world or by taking the same (one way) elevator up from the underground world. It is a simple complex that resembles a drab shopping mall with avenues of buildings, though most are inaccessible. There are multiple layers of the mall reached by riding the escalators.
A large, thickly growing forest filled with strange creatures. There are multiple routes that lead through here, with connections to many different areas. Travelling along the road produces some strange sights.
Wilderness A is a large expanse of curly plants and rocky soil reached from an Aztec arch in the Dark World. It is notable for being extremely hard to navigate through all the plants that you see. Wilderness A is split into two parts: the non-looping part and the looping part. The looping part can be accessed from the northeast corner of the area west from the gate to the Dark World. In the non-looping part, you'll see The Toriningen Party, the Aztec Rave Box, and the Barracks Settlement. The looping part contains Onsen-san's house, a towel creature that gives you the Towel effect, and an oval of plants. Walking northwards through the oval leads to the red-eyed plants and the sky garden.
The Barracks Settlement can be accessed from the Wilderness by going east and then north-west from the Dark World gate, or by entering the Docks from Hell and talking to the Pirori. It's filled with identical shacks and Pirori wandering the streets. One house contains a strange orange creature, another a path to the Mural World. By talking enough to the people, you will be teleported to FC World B.
The Sky Garden is reachable by going up through a path through the middle of an oval-shaped clump of grass in Wilderness A, heading through a gap in the fence and going up then right. The Sky Garden is at the top of a long flight of steps that look like part of an Aztec pyramid. The Falling Man event occurs on the stairs here. Voices can be faintly heard inside the beeping part of the soundtrack.
The Ghost World is found in the Sky Garden. There is a tunnel there which seems completely dark and cannot be lit up by the Lamp effect. It does not branch. The tunnel ends in a patch of flowers, which, when interacted with once, makes the screen flash slightly and changes the environment outside the tunnel into a world of blue blocks. Listening closely there seems to be faint sound of sniffing, as if crying in the background.
The Triangle Kerchief effect can be found here. To get back to the Sky Garden, enter the tunnel again and interact with the flower once more.
The Sewers can be reached by going down a manhole in the Mural World. The Nopperabou effect and Big Red can be found here. Peering inside the holes in the walls on the way to Big Red seem to be drawings that Madotsuki herself might have drawn.
Different sections can be reached from Hell or from the Big Red. The Hell section leads to the Fat effect and a shadow man who takes you to part of Wilderness A where the Barracks Settlement can be reached. The Big Red section has a vending machine and takes you back to the Sewers, not much else.
Also known as the Pastel Shoal World, this world is accessed from the igloo in the Snow World with a pink pool in the middle. Poniko lives here. The balloons teleport Madotsuki in and out of the water. The Frog effect allows her to move through the water more quickly. This is another place where voices can be heard closely in the background.
The Underground world is a small location accessed by sleeping in a randomly chosen "dream bed". Following the Staircase of Hands, you go to a storage area. If one wishes to explore this area, either the Umbrella or Yuki-onna effect must be used in order to douse the flames that block your path. An elevator can be taken to the mall, while an additional passage located at the top end of the storage room leads to the spaceship.
Reached by travelling through the Underground World, Seccom Masada-sensei's spaceship is a monochrome environment which eventually crashes on Mars.
A red, rocky environment that is reached via the Mars event. The boiler room can be entered by using the midget effect and climbing down the steaming vent. A point-of-no return; one must use either the Medamaude effect or awaken in order to leave this area. The UFO event also can occur here if Matdosuki equips the Cat effect and meows repeatedly.
Two single-screen worlds that seem empty at first, but flash with erratic television static every few seconds. One houses an invisible maze. They must be worked through to enter the FC World.
Also known as the Cubes Maze, the Teleport Maze can be found by talking to The Jellyfish in the Frog Path section of the Dense Woods B. Toriningen occasionally teleport you here, too. The exit leads to the inside of the Wilderness FC Portal.
The Guillotine World is found by going through the bleeding part of the wall in the Bed Room. An openly-looping world, it contains Lunatic Toriningen and the Guillotine which gives you the Severed Head effect. You must escape by climbing into a closet that is not inhabited by [[list of characters#Unnamed (Guillotine World)|A strange creature. The regular Guillotine world is quite small and has only two Toriningen, but it loops quickly, giving the illusion of there being many more. There is also a 1/8 chance of appearing in a much larger version of the Guillotine world that is four times larger and has no less than 8 Toriningen running around. This makes it much harder to find the guillotine and the escape closet, and it is tricky to avoid so many Toriningen at once.
A diagonal staircase accessible from sleeping in a random bed in the dream world. If you go upstairs, you wake up again, but if you continue downstairs you reach The Underground World
The Mall Roof
By entering the door to the mall, before going into the main area go up the adjacent staircase to find a white doorway that brings you to the mall's roof. Here you can activate The Witch's Flight event.
