Nightmares are not associated with specific physical findings.

Heart rate and respiratory rate may increase or show increased variability before the child awakens from a nightmare. Mild autonomic arousal, including tachycardia, tachypnea, and sweating, may occur transiently upon awakening.

Movement is uncommon owing to REM sleep–induced atonia.
