A time loop is a concept in which a person or group of people repeatedly experiences the same period of time, often leading to the same events occurring over and over. This phenomenon can be found in various forms of media, including movies, books, and video games. The characters may become aware of the loop and try to change their actions to escape it. In a time loop, the cause of the repetition can vary, ranging from supernatural elements to scientific experiments gone wrong. Popular examples include the film Groundhog Day and the video game The Legend of Zelda: Majora's Mask. These narratives often explore themes of personal growth and the consequences of one's choices.
