Understanding Nightmare Disorder

When bad dreams disrupt your life — they can be treated.

What Is Nightmare Disorder?

Nightmare disorder involves frequent, vivid nightmares that cause significant distress, disrupt sleep, and affect daytime functioning.

Occasional nightmares are normal — nightmare disorder is diagnosed when they become frequent and distressing enough to impair quality of life.

Chronic sleep deprivation from waking during the night.

Daytime fatigue, anxiety, and difficulty concentrating.

Processing underlying trauma with a therapist.

Relaxation techniques before bed can improve sleep quality.
