Beginning in late 2222, BCI users across Tiers 2 through 4 began reporting and sharing clips of what they called 'the Recursion' — a specific sensation of having lived the current moment before, triggered not by memory but by receiving a BCI notification at the precise moment they were thinking about receiving it. The trend exploded when users began deliberately engineering the sensation through a shared predictive-algorithm plugin called Déjà.exe, which learns behavioral patterns and sends notifications timed to anticipated thoughts. At its peak in 2223, an estimated 340,000 GLMZ residents were running Déjà.exe simultaneously, and a secondary phenomenon emerged: people began experiencing Recursions they hadn't engineered, suggesting the collective data was predicting behavior it hadn't been trained on.
