In Miguel de Cervantes Saavedra's "Don Quixote," the protagonist imagines an extraordinary encounter while traveling. He becomes enamored with the idea of adventure and romance as he spots a cart adorned with royal flags. This sight ignites his belief that something fantastic is unfolding before him, leading him to a new quest filled with excitement and possibility.

Don Quixote's perception of reality is heavily influenced by the chivalric romances he has read, which fuels his imagination and propels him into a world where he views ordinary events as grand adventures. His journey reflects the themes of illusion versus reality, as he seeks to live out the noble ideals he admires, often to comedic and poignant effect.
