Introduction
Nightmares are dreams that are scary or disturbing. The themes of nightmares vary widely from person-to-person, but common themes include being chased, falling, or feeling lost or trapped. In nightmares, the person will feel unreal emotions like anger, sadness, guilt, fear, anxiety etc. These emotions will be felt even after waking up.
People of all ages have nightmares. However, nightmares are more common in children, especially those under age 10. Girls are more likely to be troubled by their nightmares than boys. Nightmares seem to be a part of normal development, and except in the case of post-traumatic stress disorder, they usually aren’t symptoms of any underlying medical condition or mental disorder. However, nightmares can become a problem if they persist and interrupt the sleep pattern. This can lead to insomnia and difficulty functioning during the day.

Causes
Nightmare disorder is a kind of sleep disorder that involves bad experiences that occur while falling asleep, during sleep or when waking up. Nightmares usually occur during the stage of sleep known as rapid eye movement (REM). The exact cause of nightmares is not known.
Nightmares can be triggered by many factors, including:
- Stress or anxiety
- Trauma (Physical or mental)
- Sleep deprivation
- Medications like some antidepressants, blood pressure medications, beta blockers can trigger nightmares.
- Substance abuse
- Mental disorders like Depression and physical disorders such as heart disease or cancer. Having other sleep disorders that interfere with adequate sleep also can cause nightmares.
- Post-Traumatic Stress Disorder (PTSD)
- Scary books and movies
Pathophysiology
Sleep is divided into 2 states: rapid eye movement (REM) and nonrapid eye movement (non-REM). REM and non-REM sleep alternate in 90- to 100-minute cycles. REM sleep is characterized by EEG activity similar to a wakeful pattern. In older children and adults, 75% of sleep is non-REM sleep, which consists of 4 stages.
Dreaming and nightmares occur during REM sleep, and they are more frequent in the second half of the night.
Nightmares are often confused with night terrors, which are episodes of extreme panic and confusion associated with vocalization, movement, and autonomic discharge. Night terrors occur during non-REM sleep. Children with night terrors are difficult to arouse and console and do not recall a dream or nightmare.
There are no specific tests for diagnosing nightmares.
But a sleep study can help in the diagnosis. During a sleep study, the patient spends the night in a laboratory. Sensors monitor various functions, including:
- heartbeat
- brain waves
- breathing
- blood oxygen levels
- eye movements
- leg movements
- muscle tension
Treatments
Treatment is not needed in most cases of nightmares. However, any underlying medical or mental health problems should be addressed.
Counselling or stress-reduction techniques will be beneficial if any of the following conditions is triggering the nightmares:
- anxiety
- depression
- stress
In rare cases, medication for sleep disturbances may be advised.
Prognosis
Nightmares have a long-term prognosis. Treatment will help improve the quality of sleep.
Complications
- Excessive daytime sleepiness, which can lead to difficulties at school or work, or problems with everyday tasks, such as driving and concentrating
- Problems with mood
- Resistance to going to bed or to sleep for fear of having another bad dream resulting in disturbed sleep
- Suicidal thoughts or suicide attempts
