Yume Nikki:Number World

The Number World is one of the 12 original locations accessible directly from the Nexus.
It is an enclosed world characterised by confusing hallways and long numbers that range from 0 to 236,800,954,213,315,784 stretching across the floor.

The parallax background appears to be a picture of the Number World map, making the hallways even more confusing to navigate. The walls are repeating pictures of faces that look like zippers with legs and arms. They seem to be biological, as they can be seen bleeding in a couple of places and have expressions that change from time to time.

There are no effects in the main part of the Number World, but there are effects in some of the deeper locations accessible from here.

Points of Interest

• Steve 'Leif' Kareha can be seen here, slowly moving across the canal at the bottom. He can be drawn faster by the Cat effect. There also also three other NPCs that change appearance under the stoplight.
• One of the Toriningen in the Dream World may teleport you into an enclosed room here that has the Japanese hiragana letter 'あ' (A) on the floor. Walking over it causes the whole floor of the Number World to be flooded with あs. This is sometimes interpreted as a literation of the sound Uboa makes, or Madotsuki herself screaming, evidence of possible claustrophobia.

The Stabbing Room

The landscape model/mask-like object in the empty stabbing room.

The Stabbing Room is found behind the door somewhere at the top of the Number World that is blocked by an NPC. Stabbing the NPC with the Knife effect, or moving it with the Cat effect allows Madotsuki to enter the room.
The room itself is packed with a different kind of identical NPCs, so to move around the room, Madotsuki has to clear a path by killing them. Like most other NPCs, they do not retaliate. Nothing happens if you stab them all, but it is an efficient way of collecting coins. There is a blue landscape model in the lower part of the room.

The Stairway

The tile that must be stabbed to gain access to the Stairway

• The entrance to the Stairway (in the furthest right part of the Number World) is not always available. There is a random chance determined when Madotsuki falls asleep that the tile will change to allow her through. When the face has an open mouth, it can be stabbed with the Knife effect to allow entry.
• KyuuKyuu-Kun is found here, rubbing the banister.
• The door at the top of the stairway is the same as Madotsuki's bedroom door. When she walks through it, the FACE event occurs, which leads to Madotsuki being forced to awaken. The significance of this event is subject to much speculation.

The Lamp World

The Lamp World

Like its name implies, it's a world filled with lamps. It's quite large and in openly-looping, which makes it easy to get lost in.

• Unlike the lamps in the Puddle World, the lamps cannot be switched on and off. Most of the lamps are off, but there are a few rings of 5 lamps that are switched on.
• The Lamp effect can be found here, by interacting with A small lamp character with feet.
• There is a second door that leads to back to the Number World, to an enclosed space by the canal where if you wait for a while (or use the Cat effect you will see Steve 'Leif' Kareha.
• There is also an alternate exit by interacting with an unusually short lamp that leads to an island in The Checkered Tile Path where you can see Closet Madotsuki.

The Bed Room

The Bed Room

The Bed Room is found behind the door on the far left of the Number World. There are 71 beds and a sane Toriningen here.

• Most of the beds are occupied, but one bed (the centre bed on the 5th row) can be used. It is one of the beds that may teleport MAdotsuki to The Staircase of Hands.
• By stabbing the Toriningen and opening the third closet from the left, Madotsuki is transported to Mini Hell.
• The Guillotine World can be reached by entering the bleeding section of the wall, where the [[Effects#Severed Head|Severed head effect is received.
