A story within a story, also referred to as an embedded narrative, is a literary device in which a character within a story becomes the narrator of a second story. Multiple layers of stories within stories are sometimes called nested stories. A play may have a brief play within it, such as in Shakespeare's play Hamlet; a film may show the characters watching a short film; or a novel may contain a short story within the novel. A story within a story can be used in all types of narration including poems, and songs.
