Understanding Narrative Perspective in Prose

In the following passage from a novel, the narrator observes a vibrant city during the transition from dusk to nighttime. This first-person narrative perspective influences the portrayal of both the setting and the narrator's emotions. Read the passage carefully and consider how the narrative perspective shapes the description and theme.

“As the sun dipped below the horizon, the city came alive, its lights flickering on as if awakening from a dream. I walked through the streets, each softer shadow pulling me deeper into a tapestry of sounds and scents. Yet, amidst this vibrancy, I felt a strange disconnection, as if I were a mere observer, watching a theater play unfold without participating.”
