Title screen of Yume Nikki

Yume Nikki (ゆめにっき, Dream Diary) is a free game made in RPG Maker 2003, created by mysterious Japanese developer KIKIYAMA. It first launched on June 26, 2004 under version 0.00. The latest version is 0.10, which came out on October 1st, 2007. The game hasn't been updated since then.

In Yume Nikki, you play as a girl named Madotsuki who lives in a small room, and refuses to leave. There isn't much to do in her room itself, but once you go to bed you get to explore various worlds within her dreams, in search of 24 "effects".

The gameplay of the game itself is similar to that of Yume 2kki, you go to sleep and explore different dream worlds, some ominous, some cheery.

The game became so popular to the point where it has garnered a sizable fanbase, who have since created countless fangames, such as Yume 2kki. For more information, please see the Yume Nikki Wiki.

References in Yume 2kki

Yume 2kki is one of the most popular fangames out there, alongside games like .flow, Me, Yume Nisshi, Yume Graffiti and Fleshchild, to name a few.
Since Yume 2kki is also the supposed "sequel" to Yume Nikki, it has been heavily influenced by it and contains a lot of references to the original game.

The game's name in the first place is a pun on the original "Yume Nikki", since "ni" in Japanese is also the number two, hence "Yume 2kki".
A lot of the endings are parodies of the ending of Yume Nikki.

Locations

The Shield Owl World greatly resembles the Shield Folk World from Yume Nikki. Even their fan names are similar in this regard.
The Abandoned Factory can be seen as a reference to the Sewers, where Big Red is found.
You could say the Dark Forest is reminiscent of the The Dense Woods.
- You could also say the Forest Pier is reminiscent of the Witch's Island (Ironically, the Dark Forest and the Forest Pier are completely unrelated and isolated from each other, despite this).
The Neon City is visually similar to the Neon World, yet also thematically similar to the White Desert.
It's possible that Marijuana Goddess World was in-part inspired by the Graffiti World because of the different tiles that make noises when you step on them.
Forest World and the Digital Forest both resemble Forest World, with their trees and crops.
The Dressing Room in Urotsuki's Dream Apartments has an unreachable mannequin bearing the window from Madotsuki's shirt.
Both the Hidden Shoal and the False Shoal are references to The Pink Sea.
The old UFO vaguely resembled Masada's ship.
The Baddies Bar is very similar to Number World in terms of design, while also similar to The Torinigen Party in the aspect that they are both places that Chasers hang out.
A portion of the ground in the Extraterrestrial Cliffside bears a strong resemblance to Uboa.
- The GB Fields also have something like this.
Marina's House (externally and internally) resembles Poniko's House. You can even turn the lights off!
Static Noise Hell resembles Hell in terms of appearance, and the crossroad where you start off is reminiscent of its lesser counterpart, Mini Hell, complete with a transparent Urotsuki standing in the center.
Gray Relic World heavily resembles Mural World in appearance and design.
The Windows key of Matoran Keyboard is labeled with the window from Madotsuki's shirt.
The overall layout of the Obsidian Plains is a direct reference to the Forest World.
The Gulliver Desert bears a striking resemblance to the White Desert, down to the way its sub-areas are accessed.

Events / NPCs

By interacting with the yellow-tinted window in the Never-Ending Hallway, the Madotsuki's Room event begins, with the player being trapped for a period of time in a glitched out version of Madotsuki's Room before the screen completely fades to static.
The Red Nail Passage in Nail World has pillars across it. Upon interaction, they make an image appear on the screen for a few seconds. This is similar to the Drawings in the Sewers event in the Sewers, in which there are pictures that appear when interacting with the holes in the wall.
In the Sky Kingdom, there is an NPC that looks a lot like the infamous Uboa from Yume Nikki, nicknamed Dogboa. Older versions of Marina's House featured another reference to Uboa, nicknamed Not!Uboa, but all connections to it have since been removed.
The first channel in the TV Room is an Aztec creature that greatly resembles the Aztec Rave Monkey. The same creature appears in the parallax background of Shield Owl World, Cosmic World, and the Radiant Ruins, perhaps in reference to the same thing happening in Yume Nikki's Forest World and Block World. A similar event occurs in the Ancient Crypt. Channel #10 features Urotsuki spinning around like Monko's full-screen event, and channel #16 is a reference to the KALIMBA TV Channel event.
There is an NPC in Pillars World that mirrors Onsen-San.
- The Streetlight Garden also features a character like this, nicknamed Onsen's Cousin.
There's a random chance in the Neon City you might stumble across It Came From Behind, a red character that floats across the screen for about three seconds while making a noise, in a similar manner to Takofuusen. Similar events can also occur in Paradise, Word World, the Neon Sea, and the Monochromatic Abyss.
The Abandoned Factory contains an event where Urotsuki is eaten by a large red monster, similar to Big Red, and taken to a dark world with pinwheels and a multicolored panorama, similar to Windmill World.

Soundtrack

The default theme of Urotsuki's Computer is an arrangement of Yume Nikki's ending theme.
The BGM of the Mirror Room in Jigsaw Puzzle World is Yume Nikki's save theme played backwards.
The music of the Madotsuki's Room event is an odd rendition of the NASU music from the original game.
