Recurring Nightmares: Causes and How to Manage Them

You wake up in a sweat, heart pounding. The same dream again. Or a similar one. For the third week now. Falling asleep again is scary — what if it happens again.

Chronic nightmares are not just a "bad dream." They are a disorder with specific causes and specific treatment methods.

1. Why Nightmares Occur

Nightmares primarily occur during REM sleep — the phase when daily emotional experiences are processed. The brain "digests" emotionally charged events.

Causes of chronic nightmares:

• PTSD — nightmares about a traumatic event are among the diagnostic criteria
• Anxiety disorders — the brain continues to "scan for threats" even during sleep
• Depression
• Acute stress
• Medications — some antidepressants, beta-blockers, blood pressure medications
• Alcohol — suppresses REM in the first half of the night, "returning" it with excess in the second
• Sleep disorders (apnea)

2. Nightmare Disorder

A diagnosis of "nightmare disorder" is made when there are:

• Recurrent nightmares (several times a week)
• Significant sleep disturbance or daytime impairment
• Fear of falling asleep

3. Evidence-Based Treatment Methods

Image Rehearsal Therapy (IRT) — a first-line method:

1. Recall and write down the nightmare
2. Change its ending to a neutral or positive one (of your choice)
3. "Rehearse" the new version in your imagination for 15–20 minutes a day
4. Do this daily for 2–3 weeks

Exposure therapy: for nightmares related to PTSD — as part of EMDR or CPT.

Medications: Prazosin (an α1-blocker) has been proven to reduce nightmares in PTSD.

4. What Reduces Nightmare Frequency

• Reducing pre-sleep stress
• Abstaining from alcohol
• Treating the underlying disorder (PTSD, anxiety)
• Regular sleep schedule
