During adolescence and young adulthood, girls are more likely to experience nightmares than boys. Some individuals may continue to have nightmares into adulthood.

While nightmares are common, nightmare disorder is less frequent.

This condition is characterized by recurrent nightmares that cause significant distress, disrupt sleep, and interfere with daily functioning or create a fear of sleeping.

Symptoms of Nightmares

Nightmares are more likely to occur during the latter part of the night and can happen infrequently or several times a night.

Although episodes are usually brief, they can lead to difficulty returning to sleep.

Common features of nightmares include:

• Vivid and Disturbing Content: The dream feels real and unsettling, often becoming more distressing as it progresses.
• Threatening Themes: The storyline often revolves around safety or survival threats, but may include other disturbing scenarios.
• Awakening Effect: The dream typically causes you to wake up.
• Negative Emotions: Feelings of fear, anxiety, anger, sadness, or disgust may linger after waking.
• Physical Responses: You might experience sweating or a racing heartbeat while in bed.
• Clear Memory: Upon awakening, you can recall details of the dream.
• Difficulty Returning to Sleep: The distress caused by the nightmare can make it hard to fall back asleep.

Nightmares are classified as a disorder if you experience:

• Frequent occurrences
• Significant daytime distress or impairment, such as anxiety or fear related to sleep
• Concentration or memory issues tied to the dream content
• Daytime sleepiness, fatigue, or low energy
• Difficulty functioning at work, school, or in social situations
• Behavioral problems related to bedtime or fear of the dark

For parents, a child with nightmare disorder can lead to substantial sleep disturbances and stress.

When to Seek Medical Help

Occasional nightmares usually aren’t a concern. If your child experiences nightmares, you might mention them during a routine check-up. However, consult a doctor if nightmares:

• Occur frequently and persistently
• Regularly disrupt sleep
• Cause fear of going to sleep
• Lead to daytime behavioral issues or functional difficulties

Causes of Nightmares

Nightmare disorder, classified as a parasomnia, involves undesirable experiences during sleep or waking.

Nightmares generally occur during rapid eye movement (REM) sleep, but their exact causes are not fully understood.

Potential triggers for nightmares include:

• Stress and Anxiety: Everyday stressors or significant life changes can lead to nightmares. Anxiety can also increase their frequency.
• Trauma: Experiences such as accidents, injuries, or abuse are often associated with nightmares, particularly in those with post-traumatic stress disorder (PTSD).
• Sleep Deprivation: Irregular sleep patterns or lack of sleep can heighten the risk of nightmares, and insomnia is often linked to them.
• Medications: Certain medications, including some antidepressants and those used for blood pressure or Parkinson’s disease, may trigger nightmares.
• Substance Misuse: Alcohol and drug use, as well as withdrawal, can lead to nightmares.
• Other Disorders: Mental health issues like depression and various medical conditions, such as heart disease or cancer, can be associated with nightmares. Additionally, other sleep disorders can contribute to their occurrence.
• Scary Media: Reading frightening books or watching scary movies, particularly before bedtime, may also provoke nightmares for some individuals.
