The Wonderland System meme originates from a niche corner of TikTok and internet subcultures where creators document their experiences with Dissociative Identity Disorder (DID) or 'OSDD'. This specific system gained notoriety for its elaborate fantasy-themed internal world and a vast number of alters, which led to both genuine interest and widespread parody across social media. Today, the template is used to satirize complex situations, overwhelming choices, or to reference the specific aesthetic of 'system' culture. It serves as a visual shorthand for entering a chaotic yet highly organized internal universe that feels like a rabbit hole of personality and lore.
