The Nexus, (a.k.a. the Door Room) is the first room of the dream world, serving as the central hub from which all other locations can be eventually reached.
The room is one of the iconic locations in Yume Nikki with its characteristic colorful doors and concentric Aztec-inspired floor design.
It is a relatively small room with thirteen doors arranged in a circle around the centre. The top door is set slightly farther from the centre than the others, and leads back to Madotsuki's Dream Room.
The other 12 respectively lead into the top-level worlds known as the 'original locations'.
Clockwise from the top, they are:
- The Number World
- The Neon World
- The Shield-Folk World
- The Candle World
- The Eyeball World
- The Graffiti World
- The Mural World
- The Snow World
- The Dark World
- The Puddle World
- The Block World
- The Forest World
There are many locations that cannot be reached directly from the Nexus, known as Some locations. They can only be reached by travelling through the original locations and some locations require the player to traverse through many worlds before they arrive. All of the original locations have doors and portals leading deeper into the dream world, so dead ends are rare to find in Yume Nikki.
Effect Eggs
The Nexus is the only room where Madotsuki's Effects can be dropped. This is done by equipping them and pressing 5.
Each effect appears as a unique egg that is analogous to the effect is contains, for example the Medamaude egg has an eye on it, the Midget egg is small and the Neon Egg strobes bright colors.
Wherever the eggs are placed, they will arrange themselves into their correct positions when Madotsuki leaves and re-enters the room. When all 24 effect eggs are in place, they make two concentric circles around the centre. This produces a change in the real world, allowing the player to end the game.
Trivia
- Strangely, the Number World Door makes a different sound to all the rest. All other doors click when they shut, but the Number World door makes a heavier thud. This is clearly heard when travelling back to the Nexus from the Number World. This seems to highlight the Number world as more significant.
Directly through this world is the corridor that leads to KyuuKyuu-Kun's staricase. In the corridor, the Nexus' floor pattern can be seen as the scrolling background, and the door at the top of the staircase is identical to Madotsuki's Bedroom door. - The Nexus is one of the few locations that have no background music, which draws attention to the sound of Madotsuki's footsteps, creating a sense of awe.
