The poem describes a speaker's painful nights spent alone in bed, unable to sleep due to nightmares. Over the past two nights, the speaker has been awakened screaming from fiendish dreams filled with terrible images representing mankind's capacity for horror. By the third night, after again waking from these dreams, the speaker weeps like a child, overcome with strange sufferings. While the dreams seem fitting punishment for those deeply stained by sin, the speaker asks why these pains must fall upon him.
