In Cormac McCarthy's novel "The Road," the protagonist grapples with nightmares that represent his deepest fears and traumas. These dreams haunt him, making the nighttime a source of dread rather than rest. The line underlines the idea that the burdens of reality can sometimes feel lighter than the subconscious struggles faced during sleep.

This mental turmoil emphasizes the fragility of his psyche as he navigates a harsh post-apocalyptic world. The fear of revisiting painful memories in dreams reflects the broader theme of survival and the emotional toll it takes, suggesting that confronting one's inner demons can be more daunting than facing external challenges.
