A brief, structured therapy for recurrent nightmares that involves rescripting the nightmare into a less distressing version and mentally rehearsing it while awake.

What Is Imagery Rehearsal Therapy?

Imagery rehearsal therapy is a brief, structured cognitive behavioral treatment specifically for recurrent nightmares, including trauma-related nightmares, that involves consciously rewriting (rescripting) the nightmare into a less distressing version and mentally rehearsing this new version while awake.

How It Works

This approach is based on the understanding that recurrent nightmares can become an independent, learned sleep disturbance, and that deliberately rehearsing a revised, less distressing version of the dream while awake can reduce the frequency and intensity of the original nightmare. This description uses original explanatory language.

What Happens During Therapy?

Sessions involve selecting a recurrent nightmare, working with the client to rewrite it into a less distressing version in any way they choose, and then practicing mentally rehearsing this new version for a few minutes daily.

Evidence and Effectiveness

Research supports imagery rehearsal therapy for reducing the frequency and distress of recurrent nightmares, including trauma-related nightmares, with evidence from multiple randomized controlled trials.

Who May Benefit?

Imagery rehearsal therapy may be considered for people experiencing recurrent, distressing nightmares, including those related to PTSD or occurring independently as nightmare disorder.

Limitations and Considerations

Imagery rehearsal therapy specifically targets nightmares and does not address other PTSD symptoms directly, so it may be used alongside broader trauma treatment when other symptoms are present.

Finding a Qualified Therapist

Imagery rehearsal therapy is delivered by psychologists, sleep specialists, and other mental health professionals trained in this specific technique.

How Long Does Therapy Take?

Imagery rehearsal therapy is often delivered over a brief course of approximately 4 to 6 sessions, reflecting its focused, brief design.

Therapy vs. Medication

For nightmares, imagery rehearsal therapy and medication are not necessarily competing options and may be used alone or in combination, in consultation with a qualified healthcare professional.

What Conditions Is It Used For?

Nightmare Disorder

A sleep disorder involving repeated occurrences of extended, extremely dysphoric, well-remembered dreams that cause significant distress or impairment.

Post-Traumatic Stress Disorder

A condition that can develop after exposure to a traumatic event, involving intrusive memories, avoidance, negative mood changes, and heightened arousal.

Related Therapy Types

Cognitive Behavioral Therapy (CBT)

A structured, time-limited psychotherapy that helps people identify and change unhelpful thought patterns and behaviors that contribute to emotional distress.

Prolonged Exposure Therapy (PE)

A structured trauma-focused therapy that uses repeated, guided recounting of the traumatic memory along with real-world exposure to safe but avoided situations.
