I couldn't sleep all night; a foghorn was groaning incessantly on the Sound, and I tossed half-sick between grotesque reality and savage, frightening dreams.
Chapter 8 · Narrator
Context
This is the opening of Chapter 8. Nick has just witnessed the confrontation at the Plaza Hotel, Myrtle Wilson's death, and left Gatsby standing vigil outside the Buchanans' house. He returns home but cannot sleep, tormented by the day's events.
Analysis
The personification of the foghorn 'groaning' externalizes Nick's psychological distress, transforming the landscape into a sympathetic expression of anguish. The collapse of boundaries between 'grotesque reality' and 'savage dreams' signals that the events of Chapter 7 have ruptured Nick's capacity to distinguish waking horror from nightmare—reality itself has become as irrational and terrifying as the unconscious, marking the point at which the novel's world loses its coherence for the narrator.
How to Use in Essay
Useful for essays on how the novel uses Nick's psychological state to register moral crisis, or for analyzing how Fitzgerald blurs the boundary between realism and expressionism in the novel's final movement.
