As Yume Nikki is a game about dreams, beds 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, 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 north of the Nexus entrance to a lone candle then going straight east, next to the wandering Toriningen.
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.
Using the Snow World bed is required in order to experience the Melting Madotsuki event, as using the Yuki-onna effect will cause persistent snowfall that results in the Blazing Corridor flames being put out.
Block World
The dream world bed found in Block World is southeast of the Nexus entrance. The easiest way to navigate there is to go west and follow the contour of the blocks to the bottom. The Hat and Scarf effect is south of the bed.
Number World's Bed Room
By going slightly south and all the way west from the Nexus entrance, the player will come across the door to the Bed Room, a subarea in Number World filled with beds. There are, in total, 71 beds in the Bed Room, however, most are either occupied or unreachable. The one that can be entered is the center bed in the fifth row.
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 other four will do nothing. The bed selected to do this is randomly chosen when Madotsuki falls asleep. If the Poop Hair effect has not yet been obtained, the bed in Candle World will be guaranteed to send Madotsuki to the Staircase of Hands, although another bed may still be selected by the random chance.
Once Madotsuki is sent to the Staircase of Hands, she can either go upwards to return to the bed she fell asleep in (which may 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.
Spaceship
In addition to the beds listed above, there is also a unique bed on the Spaceship. It has a 1/6 chance of causing the Spaceship Crash event whenever Madotsuki enters the bed and waits for 15 seconds.
The Spaceship can only be reached through Underground World, which itself is reached by falling asleep in a dream world bed. 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 characters appear to be standing on top of the bed when Madotsuki gets into it. This is because the bed is moved to the lower layer when interacted with, in order to have Madotsuki appear above it.
- The unoccupied Number World beds that are normally unreachable due to the surrounding beds cannot be slept in, even if accessed through the noclip glitch.
- The bed in the Spaceship has a black filter cover the screen once Madotsuki falls asleep in it. This is removed in the English Steam release of Yume Nikki due to an error in the indexing of the black image used, making it so there are no visual changes once Madotsuki enters the bed.
- In version 0.04, if the player attempts to sleep in the Candle World bed from above, they will be able to walk around while still technically in the bed, and will be invisible.
- Older versions of the game had more beds that were later removed:
- There were four beds located in the upper section of the Checkered Tile Path, which did nothing. These beds were removed in version 0.07 alongside a reworking of the area's structure.
- Block World had an event known as the Toriningen's Bed event, which consisted of a long path leading to a single bed. Getting into this bed would make an unavoidable lunatic Toriningen appear, which would trap Madotsuki in Footprint Path B upon interaction. This event was removed in version 0.07.
- Lamp World was originally accessible from the Nexus and had a completely different appearance. In this state there was a room filled with beds alongside a single isolated bed. The isolated bed could be accessed by getting caught by the Toriningen in the Checkered Tile Path (which now traps Madotsuki in the Docks). Sleeping in any of the beds here dims the lights. These beds were revamped into Number World's Bed Room in version 0.08.
