Nightmare in poetry plunges into the surreal, grotesque, and terrifying—monsters, falling, suffocation. Poets use it to access subconscious fears, trauma, or political horrors, as in Goya's "Sleep of Reason" or Coleridge's "Christabel." Nightmare disrupts narrative logic, employing distorted time and irrational imagery. It invites readers to confront what waking consciousness represses, making the poem a space for exploring the dark side of the psyche.

Nightmare in poetry plunges into the surreal, grotesque, and terrifying—monsters, falling, suffocation—accessing subconscious fears, trauma, or political horrors. In teaching, distinguish nightmare from horror: nightmare is a frightening dream, while horror is a response to the grotesque. Nightmare disrupts narrative logic, employing distorted time and irrational imagery. It invites readers to confront repressed darkness. Students should examine how poets use surreal imagery, non-linear chronology, and oppressive atmosphere to convey nightmare's disorienting, terrifying grip.
