AI: The Somnium Files Wiki

A Somnium (plural: Somnia), sometimes called a Dreamworld, is a type of world that exists within the universe of AI: THE SOMNIUM FILES.

Somnia are worlds that exist within the subconsciousness of a person. They are shaped by the dreams and memories of the people in the realm of reality.

The Psync Machine allows the Psyncer to delve into the subject's Somnium and interact with their dream to find information. The appearance and nature of each Somnium is created from memories of the subject.

Trivia

  • The name of the Somnia in AI: THE SOMNIUM FILES are references to the 1929 song, and the 1952 film it inspired, named "Singin' in the Rain." The word "singin'" is swapped for "psyncin'" (with one exception swapping it for "sinkin'"), the last word is replaced with a rhyme to "rain," and all the letters are capitalized except for the "ai" vowel pair at the end of the phrase.[1]
    • The main soundtrack for the game, REVERIES IN THE RaiN, keeps the word "rain" at the end, while switching "Singin'" for "Reveries."
  • The name of the Somnia in AI: THE SOMNIUM FILES - nirvanA Initiative are two-word phrases that have an acronym of "NI", referencing Nirvana Initiative and/or the number 2 (二, Ni), itself a reference to the game's status as the 2nd entry and/or the main thematic number of the game.
