When Nightmares Won’t Let You Rest: Understanding Trauma-Related Night Terrors

“Sleep, those little slices of death — how I loathe them.” – Edgar Allan Poe

From a psychological perspective, nightmares are your mind’s attempt to process what feels too overwhelming to deal with while awake.

Nightmares are more than just bad dreams. For many people who have experienced trauma, they can become relentless, exhausting, and terrifying — a nightly replay of what the mind can’t forget and the body can’t escape.

At Arcadian Clinic, we understand how trauma-related nightmares can impact your emotional wellbeing, physical health, and sense of safety. They’re often overlooked in mainstream mental health conversations — but they’re not uncommon, and you don’t have to live with them forever. Let’s explore what causes trauma-related nightmares, why they happen, and how therapies like Nightmare Rescripting can help.

What Are Trauma-Related Nightmares?

Trauma-related nightmares are vividly distressing dreams that replay or symbolically represent past traumatic events. They often occur in people with Post-Traumatic Stress Disorder (PTSD) or Complex PTSD, but they can also be present in those without a formal diagnosis.

Unlike ordinary bad dreams, trauma nightmares tend to:

• Occur repeatedly over time

• Wake the person from sleep, often in panic or distress

• Feel overwhelmingly real or vivid

• Involve either literal replays or symbolic themes of helplessness, fear, or threat

How Nightmares Affect Mental Health

Nightmares can lead to:

• Sleep avoidance: Clients often fear going to sleep, resulting in chronic insomnia

• Emotional exhaustion: Lack of rest reduces resilience, sharpens emotional reactivity, and increases symptoms of depression or anxiety

• Daytime flashbacks: Distressing dreams can linger into the day, making it hard to focus, feel safe, or stay present

• Isolation: Clients may feel ashamed, confused, or misunderstood — especially if others minimise their symptoms

Client Story: Samira, 34, experienced trauma as a teenager. “I wasn’t scared of sleeping. I was scared of what I’d seewhen I did. I’d wake up shaking, crying, unable to breathe.”

Why Do We Have Trauma Nightmares?

From a psychological perspective, nightmares are your mind’s attempt to process what feels too overwhelming to deal with while awake. The brain, particularly the amygdala, stays hyperactive in trauma survivors — even during sleep.

During REM sleep (the stage associated with dreaming), most people process memories and regulate emotion. In PTSD, however, the memory becomes stuck in raw, unprocessed form, and dreaming simply replays the distress. Instead of healing, the mind re-experiences.

What Is Nightmare Rescripting?

Nightmare Rescripting, sometimes referred to as Imagery Rehearsal Therapy (IRT), is a clinically validated approach that helps clients change the narrative of their nightmare while awake. The aim is to reduce the emotional intensity and frequency of the nightmares.

How it works:

1. Identify the recurring nightmare

2. Describe the dream in detail in a safe, contained space with your therapist

3. Re-script the dream — changing how it ends, inserting new characters, or altering the environment

4. Rehearse the new version in your mind regularly while awake

🧠 Why it works: Research shows that repeating the new version reduces the power of the original nightmare, helping your brain store the traumatic memory in a more adaptive, less distressing way.

What the Science Says

• A study published in Sleep journal found that 70% of participants experienced a reduction in nightmare frequency after just a few sessions of nightmare rescripting.

• NICE and APA both endorse imagery-based treatments for trauma-related sleep disturbances.

• It’s particularly effective for survivors of childhood trauma, sexual assault, combat trauma, and emotional neglect.

Other Therapies That Can Help

In addition to Nightmare Rescripting, the following therapies have also shown strong results with trauma-related nightmares:

• EMDR: Helps reprocess traumatic memories and reduce emotional arousal

• NET: Allows clients to contextualise and integrate trauma narratives

• CBT for Insomnia (CBT-I): Specifically targets sleep behaviours and thought patterns that worsen nighttime anxiety

Samira's Story

After three rescripting sessions, Samira changed the outcome of her recurring nightmare — from helpless terror to safe escape. “It was like reclaiming the story,” she said. “I didn’t wake up sobbing anymore. I started to sleep again.”

In The Haunting of Hill House, the character Nell suffers terrifying dreams and sleep paralysis — symptoms rooted in grief and trauma. Her story illustrates how trauma disturbs the subconscious, and how reclaiming the narrative (literally and symbolically) can be healing.
