Narrative can be organized into a number of thematic or formal categories: nonfiction (such as creative non-fiction, biography, journalism, transcript poetry and historiography); fictionalization of historical events (such as anecdote, myth, legend and historical fiction) and fiction proper (such as literature in the form of prose and sometimes poetry, short stories, novels, narrative poems and songs, and imaginary narratives as portrayed in other textual forms, games or live or recorded performances). Narratives may also be nested within other narratives, such as narratives told by an unreliable narrator (a character) typically found in the genre of noir fiction. An important part of narration is the narrative mode, the set of methods used to communicate the narrative through a process of narration.
