This study explores the psychoanalytic dimensions in the literary works of James Joyce and Franz Kafka, two of the most influential writers of the 20th century. Both authors delve into the complexities of consciousness, identity, and existential angst through their unique narrative techniques and thematic concerns. By examining their use of Freudian and Jungian psychoanalytic concepts, this paper sheds light on the psychological depth and existential dilemmas inherent in their characters and narratives. The study aims to provide a comprehensive analysis of the psychoanalytic underpinnings in Joyce's "Ulysses," "Finnegans Wake," and "A Portrait of the Artist as a Young Man," as well as Kafka's "The Metamorphosis," "The Trial," and "The Castle."
