1. Criteria

There are repeated occurrences of extended, extremely dysphoric, and well-remembered dreams that usually involve efforts to avoid threats to survival, security, or physical integrity.

On awakening from the dysphoric dreams, the person rapidly becomes oriented and alert.

The sleep disturbance causes clinically significant distress or impairment.

The nightmare symptoms are not attributable to a substance or medication.

Coexisting mental and medical disorders do not adequately explain the predominant complaint of dysphoric dreams.

2. Context

Nightmare disorder involves repeated, vividly remembered dysphoric dreams that typically center on threats to survival, safety, or physical integrity and leave the person alert and distressed after awakening. The diagnosis becomes clinically relevant when the dreams are recurrent enough to disrupt sleep, mood, or daytime functioning.
Recall is usually clear: Unlike some other parasomnias, patients usually awaken quickly and can recall the dream content in detail.
Daytime effect: The dreams matter most clinically when they begin causing avoidance, sleep loss, anticipatory anxiety, or daytime impairment.
Context matters: Trauma history, PTSD symptoms, medications, and substance use are important parts of the workup.
Clinical focus: Useful when tracking recurrence and treatment response over time.

3. Validated scales

Nightmare Frequency Questionnaire

PCL-5

Important when trauma-related nightmares are part of a broader PTSD picture.

When to seek professional help

Seek urgent help if there are thoughts of suicide, self-harm, or feeling unable to stay safe.³
Seek urgent help if there are thoughts of harming someone else, escalating violent urges, or loss of behavioral control.³
Take hopelessness seriously, especially if the person feels trapped, cannot imagine staying safe, or is withdrawing from support.⁴
Use emergency services if there is immediate danger, severe agitation, psychosis, intoxication, or inability to care for basic needs. In the United States, call or text 988 for crisis support and call 911 for immediate danger. Use emergency services in your region if you are outside the U.S.³
