How does James Joyce's use of stream-of-consciousness in "Ulysses" challenge traditional narrative structures?

James Joyce's "Ulysses" is often celebrated for its innovative use of the stream-of-consciousness technique, a narrative style that seeks to depict the multitudinous thoughts and feelings passing through a character's mind. This method diverges sharply from conventional linear storytelling, presenting a more chaotic and fragmented portrayal of reality. Stream-of-consciousness allows readers to immerse themselves in the protagonist's introspective journey, blurring the lines between thought and action, past and present. By examining how Joyce employs this technique, one can explore its implications on the reader's comprehension and engagement, and how it redefines traditional narrative expectations in literature. What are the consequences of this narrative style on the development of the novel's themes and the reader's experience?
