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 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.
Block World
The dream world bed found in Block World is southeast of the Nexus entrance. The easiest way to navigate there is to first 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. Only one can be entered: the center bed on the 5th 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 others 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 you 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. 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 15 seconds.
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 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 you interact with it, in order to have Madotsuki appear above 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 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. This makes 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 still be able to walk around despite being in the bed, albeit their sprite will be completely invisible.
- In the earliest obtainable version of the game, 0.04, there were several beds that were later removed from the game. These beds served different purposes:
- There were four beds located in the upper section of the Checkered Tile Path, though they did nothing as the Staircase of Hands did not exist yet. These beds were removed in 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 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 you in the Docks). Sleeping in any of the beds here simply dims the lights, as the Staircase of Hands did not exist yet. These beds were revamped into Number World's Bed Room in 0.08.
- It's possible that the dimmed lights upon getting into these beds were reworked or meant to test the dimmed lights that appear upon getting into the bed in the Spaceship.
