Adult Night Terrors: Causes, Symptoms, and How to Stop Them

Night terrors are often thought of as a childhood problem, but adults can experience them too. Adult night terrors can be confusing, frightening, and disruptive—not only for the person experiencing them, but also for their partner or family members.

If you or someone you love has episodes of intense fear, screaming, or sudden awakening during sleep with little or no memory of it the next morning, night terrors may be the cause.

This guide explains what adult night terrors are, what causes them, common symptoms, and practical steps you can take to manage or stop them.

What Are Night Terrors?

Night terrors (also called sleep terrors) are a type of parasomnia, which is an unusual behavior during sleep. They occur during deep non-REM sleep, usually in the first third of the night.

Unlike nightmares, which happen during REM sleep and are often remembered, night terrors:

• Happen during deep sleep
• Cause sudden arousal with intense fear
• Are usually not remembered clearly the next day
• Are difficult to interrupt

During a night terror episode, a person may appear awake—but they are not fully conscious.

Symptoms of Adult Night Terrors

Night terrors in adults can vary in severity, but common signs include:

• Sudden sitting up in bed
• Screaming or shouting
• Intense fear or panic
• Rapid breathing
• Racing heart
• Sweating
• Confused or glassy-eyed appearance
• Difficulty being comforted
• No memory (or only vague memory) of the event

Episodes typically last a few minutes, but in some cases can last longer. Afterward, the person usually returns to sleep.

Because adults are physically larger and stronger than children, episodes can sometimes include:

• Thrashing
• Kicking
• Running out of bed
• Aggressive movements

This can increase the risk of injury.

What Causes Night Terrors in Adults?

Adult night terrors are less common than in children. When they do occur, there is often an underlying trigger or contributing factor.

1. Sleep Deprivation

Lack of sleep is one of the strongest triggers. When you're severely overtired, your sleep cycles become unstable, increasing the likelihood of night terrors.

2. Stress and Anxiety

High stress levels, trauma, or major life changes can disrupt deep sleep. Emotional strain often plays a significant role in adult night terrors.

3. Mental Health Conditions

Night terrors may be associated with:

• Post-traumatic stress disorder (PTSD)
• Generalized anxiety disorder
• Depression

In PTSD, episodes may overlap with trauma-related sleep disturbances.

4. Alcohol or Substance Use

Alcohol, sedatives, or withdrawal from certain substances can interfere with sleep architecture and trigger night terrors.

5. Medications

Some medications that affect the brain or sleep cycles may contribute, including certain antidepressants or sleep aids.

6. Sleep Disorders

Other sleep conditions can increase the risk, such as:

• Obstructive sleep apnea
• Restless legs syndrome
• Periodic limb movement disorder

7. Family History

There is evidence that night terrors can run in families. Genetics may increase susceptibility.

Night Terrors vs. Nightmares

Understanding the difference helps guide treatment.

Night Terrors	Nightmares
Occur in deep non-REM sleep	Occur in REM sleep
Usually not remembered	Often vividly remembered
Person appears confused	Person wakes fully alert
More physical activity	Minimal movement
Hard to wake during episode	Easy to wake

If you consistently remember disturbing dreams, you are likely experiencing nightmares—not night terrors.

When to Be Concerned

Occasional night terrors are not usually dangerous. However, you should speak to a doctor if:

• Episodes happen frequently
• There is risk of injury
• You leave the bed or home during episodes
• You experience excessive daytime sleepiness
• There are symptoms of sleep apnea (snoring, gasping, choking at night)
• Mental health symptoms are worsening

In rare cases, unusual nighttime behaviors may be linked to seizures or other neurological conditions. Proper evaluation matters.

How to Stop or Reduce Night Terrors

The good news is that adult night terrors can often be reduced significantly with the right approach.

1. Improve Sleep Hygiene

Start with the basics:

• Keep a consistent bedtime and wake time
• Aim for 7–9 hours of sleep
• Avoid screens 1 hour before bed
• Keep the bedroom cool and dark
• Limit caffeine after early afternoon

Reducing sleep deprivation alone can dramatically decrease episodes.

---

2. Manage Stress

Because stress is a common trigger, addressing it directly is important.

Helpful strategies include:

• Cognitive behavioral therapy (CBT)
• Mindfulness meditation
• Deep breathing exercises
• Regular physical activity
• Journaling before bed

If trauma is involved, trauma-focused therapy can be especially effective.

---

3. Limit Alcohol and Substances

Reduce or eliminate:

• Alcohol before bedtime
• Recreational drugs
• Unnecessary sedatives

Alcohol may initially make you sleepy, but it disrupts deep sleep later in the night—when night terrors tend to occur.

---

4. Treat Underlying Sleep Disorders

If sleep apnea is present, treatment (such as CPAP therapy) may significantly reduce night terrors.

Warning signs of sleep apnea include:

• Loud snoring
• Pauses in breathing
• Morning headaches
• Daytime fatigue

A sleep study may be recommended by your doctor.

---

5. Scheduled Awakenings (For Frequent Episodes)

If night terrors happen around the same time each night:

• Set an alarm 15–30 minutes before the usual episode
• Wake fully and stay awake for a few minutes
• Repeat nightly for several weeks

This can sometimes reset the sleep cycle and reduce episodes.

---

6. Medication (When Necessary)

Medication is not usually the first option. However, in severe or dangerous cases, a doctor may prescribe medication short-term, particularly if:

• Episodes are frequent
• There is risk of injury
• Mental health conditions are involved

This decision should always be made with a healthcare professional.

---

Safety Tips During Episodes

If night terrors involve movement:

• Remove sharp or breakable objects from the bedroom
• Lock windows and doors
• Consider sleeping on a lower bed
• Gently guide the person back to bed without force

Do not try to aggressively wake someone during a night terror. This can increase confusion and agitation.

Outlook for Adults with Night Terrors

While night terrors can feel alarming, they are often manageable. Many adults experience improvement once triggers—such as sleep deprivation, stress, or alcohol—are addressed.

However, persistent or worsening night terrors deserve medical attention. They are sometimes a signal that something else needs treatment.

---

When to Speak to a Doctor

You should speak to a doctor if:

• Episodes are violent or dangerous
• You suspect seizures
• You have symptoms of sleep apnea
• Night terrors are affecting your work or relationships
• You have symptoms of depression, anxiety, or PTSD
• You experience chest pain, breathing problems, or other potentially life-threatening symptoms

Anything that could be serious or life-threatening should be evaluated promptly by a healthcare professional.

Final Thoughts

Adult night terrors are real, disruptive, and often misunderstood. They are not simply "bad dreams." They are episodes of partial awakening from deep sleep, usually triggered by stress, sleep disruption, or underlying health issues.

The good news is that many cases improve with:

• Better sleep habits
• Stress management
• Treating underlying conditions
• Reducing alcohol
• Professional support when needed

If you're concerned about your symptoms or want a clearer understanding of what you're experiencing, Ubie's free symptom checker for Night Terrors offers a quick, AI-powered assessment that can help you determine whether your episodes match this condition and guide you toward the right care.

And most importantly, do not hesitate to speak to a doctor about persistent, severe, or potentially dangerous symptoms. With proper evaluation and treatment, night terrors can often be significantly reduced—and in many cases, stopped altogether.
