Non-linear timelines refer to narratives that do not follow a straight, chronological order. Instead of progressing from the beginning to the end, these timelines can jump back and forth in time, presenting events out of sequence. This technique is often used in literature and film to create suspense or to reveal character backstories in a more engaging way. In non-linear storytelling, events may be interconnected through themes or character development rather than through a linear progression. Examples of this can be found in works like Pulp Fiction or The Time Traveler's Wife, where the audience pieces together the story from various time periods, enhancing the overall experience.
