Postmodernism is a literary and artistic movement that emerged in the mid-20th century, characterized by a general skepticism toward grand narratives and ideologies, often embracing fragmentation, paradox, and playfulness. This movement encourages writers to experiment with narrative forms and structures, reflecting a more complex and chaotic reality. It is known for its self-referentiality and blending of genres, which connects it to various writing styles, including stream of consciousness and experimental techniques.
