As Yume Nikki is a game about dreams, beds obviously have an important role in the game.
The most significant of these is the bed in Madotsuki's Room. Climbing into bed produces a three-second countdown while Madotsuki falls asleep, after which she will appear on her balcony in the dream world.
Dream World Beds
There are numerous beds within the dream world itself, some found in the most inexplicable places. There are five that can be entered initially, fairly close to the Nexus. They are located in:
If Madotsuki has the Umbrella, Severed Head, or Bicycle effects equipped, she can not get into the beds.
Madotsuki's Dream Bedroom
Madotsuki's room in the dream world is nearly identical to the one in the real world. Just like in the room's real world equivalent, the bed on the right side of the room can be slept in.
Candle World
One of the dream world's beds is located in Candle World. It can be found by going slightly north of the Nexus entrance and then going east. Wandering by the bed is a single Toriningen who, when stabbed with the Knife effect, will run abnormally fast in order to catch Madotsuki, even faster than the Bicycle effect.
Snow World
Another dream world bed can be found in Snow World. Going east of the Nexus entrance, the player will eventually come across two trees that are close to each other. Using this as a landmark, going south between the two trees will lead to the Snow World bed. The igloo leading to the Pink Sea can also be found south of this bed.
Block World
The dream world bed found in Block World is southeast of the Nexus entrance. Nearby is also the Hat & Scarf effect, which is southeast of the bed.
Number World's Bed Room
By going slightly south from the Nexus entrance and then heading west, the player will come across the door to the Bed Room, a second room in Number World filled with beds. There are, in total, 71 beds in the Bed Room, however most are either occupied or unreachable. Only one can be entered - the center bed on the 5th row.
The Staircase of Hands
Any one of the five available beds may send Madotsuki to the Staircase of Hands when she sleeps in them, while the others will do nothing. The bed selected to do this is randomly chosen when Madotsuki falls asleep.
Once Madotsuki is sent to the Staircase of Hands, she can either go upwards to return to the bed she fell asleep in (which will send her back if she sleeps in it again) or she can go downwards, leading to the Underground World and then the Spaceship, the latter of which has another bed she can get into.
The Spaceship
In addition to the beds listed above, there is also a unique bed on the Spaceship. Unlike others in the dream world, it will not send you to the Staircase of Hands, but instead has a 1/6 chance of causing the Spaceship Crash event whenever Madotsuki enters the bed and waits for a bit.
The Spaceship cannot be reached without first dousing the flames at the end of Underground World, which themselves cannot be reached without first falling asleep in the random bed listed above. This means that in order to access Mars, Madotsuki must fall asleep three times in three different beds.
Trivia
- There is a graphical error in which entities appear to be standing on top of the bed when Madotsuki gets into it.
- Using the Snow World bed is required in order to experience the Melting Madotsuki event, as using the Yuki-onna and Hat and Scarf effect combo at the Staircase of Hands or Underground World will result in the Blazing Corridor flames being put out.
- The unoccupied Number World beds that are normally unreachable due to the surrounding beds can not be slept in, even if accessed through the Noclip glitch.
