What Is the Yume Nikki Wiki?

Updated

The Yume Nikki Wiki (yumenikki.fandom.com) is a Fandom-hosted fan wiki that serves as a comprehensive index and guide to everything in Yume Nikki. It has accumulated 211 articles since May 2009, making it one of the longest-running English-language references for the game. It is written primarily for players who have already spent time in the dream world and want to discover content they may have missed — the wiki itself advises new players to immerse themselves in the game before reading it in depth.

What the Wiki Covers

The wiki documents the game's dream world and everything connected to it: characters, effects, locations, and the many events and secrets scattered across the dream sequences. Because Yume Nikki is built around exploration and the surprise of the unexpected, the wiki functions as a catalog of things a player might never stumble across on their own.

The home page frames this directly: much of the enjoyment of the game comes from the intrigue of exploration and the marvel of the unexpected, so the wiki is intended mostly to enrich the experience of players already familiar with the dream world.

Who It's For

If your goal is to look up a specific effect, location, or event you half-remember from a playthrough, the wiki is built for exactly that. If you haven't finished the game, the wiki's own advice is to hold off — the discovery is the point.
