The Number World is a world in Yume Nikki accessible from the Nexus.
Features/Effects
The Number World is a large area with confusing hallways and secret paths. The floor appears to be a picture of the Number World map. The walls are repeating pictures of faces, legs and arms. There are many numbers spread out across the floor (the numbers range from 4 to 236,800,954,213,315,784).
There are no effects in the actual vicinity of the Number World, but there are effects in its sub-worlds. These are the Lamp (in the Lamp World), and the Severed Head (in the Guillotine Room).
