A sixth way to structure your plot in a non-linear way is to use metafiction or intertextuality, which are ways of breaking the illusion of reality and incorporating other texts or references into the story. Metafiction means that the story acknowledges its own fictionality, by addressing the reader, the author, or the writing process. Intertextuality means that the story borrows, quotes, or alludes to other texts, such as myths, legends, fairy tales, or literature. Both metafiction and intertextuality can create a sense of playfulness, creativity, or criticism that challenges the conventions, expectations, or meanings of the story. However, make sure that they are relevant, clear, and respectful. Use cues such as comments, footnotes, citations, or parodies to indicate the metafictional or intertextual elements. Avoid using them too frequently or excessively that disrupt or undermine the story.
