Kollisoners

Kollisoners is a term used primarily in speculative fiction to describe individuals who are affected by what is often called the Kollison, a hypothetical phenomenon in which two or more timelines, realities, or spatial planes briefly intersect. The term is commonly stylized with a capital K and a root resembling Kollision, the German word for collision, to evoke contact between diverging realms. It is not part of established science and is used as a narrative device rather than a recognized category.

In stories, kollison events are typically brief, localized, and unpredictable, lasting from a few seconds to several minutes. During these intervals, ordinary perception may fracture: people report glimpses of alternate selves, memories that do not belong to their timeline, or sensory impressions from adjacent realities. Kollisoners are the individuals most directly affected; they may experience heightened sensitivity to environmental cues, transient abilities, or unusual physical effects within the affected zone. Long-term outcomes vary by work, ranging from shifts in personal identity to altered relationships with others.

Because the concept originated in fiction, real-world discussions about kollisoners focus on fictional ethics, safety, and aid for those who are experiencing them within stories. In many works, communities or organizations form to support kollisoners, study the events, and regulate exposure to others who may exploit their condition or misuse the phenomenon for power.
