In the anime, the theme of reality versus illusion is often explored through the use of dream sequences, unreliable narrators, or shifts in perception that challenge the viewer's understanding of what is real and what is imagined. Characters might question their own existence or the nature of their reality, leading to philosophical reflections on the nature of truth and perception. By blurring the lines between reality and illusion, the anime prompts the audience to contemplate deeper themes about identity, consciousness, and the nature of existence.
