Nightmares are vivid, disturbing dreams that often trigger strong emotional responses such as fear, anxiety, or distress. They typically occur during the rapid eye movement (REM) phase of sleep and can lead to sudden awakenings, leaving a person shaken or unable to fall back asleep.
While an occasional nightmare is common and not a cause for concern, frequent or chronic nightmares can disrupt sleep patterns and negatively impact overall mental and physical well-being. Various factors, including stress, trauma, medications, or sleep disorders, can contribute to the occurrence of nightmares.
Understanding their causes and symptoms is crucial for managing and reducing their frequency. With proper techniques such as stress management, cognitive behavioural therapy, and sleep hygiene improvements, it’s possible to decrease nightmares and improve sleep quality, ensuring better mental and emotional health.
What are nightmares?
Nightmares are vivid, unsettling dreams that typically occur during the rapid eye movement (REM) stage of sleep, often in the latter part of the night. These dreams can be intensely emotional and may include themes like falling, being chased, or encountering terrifying situations. Nightmares can feel real and leave individuals waking up with lingering fear or distress, making it difficult to return to sleep.
Common causes of nightmares There are several potential causes of nightmares, many of which are linked to physical or emotional factors:
Stress and anxiety
Nightmares are often triggered by high levels of stress or anxiety. Emotional difficulties, work pressure, relationship problems, or trauma can all increase the likelihood of bad dreams.
Trauma
People who have experienced traumatic events, such as accidents, assaults, or combat, may experience nightmares as a symptom of post-traumatic stress disorder (PTSD). These nightmares often replay or symbolise the traumatic experience.
Sleep disorders
Conditions like sleep apnea, insomnia, or restless legs syndrome can disrupt sleep patterns and lead to nightmares.
Medications and substances
Certain medications, particularly antidepressants, blood pressure medications, and sleep aids, can cause vivid dreams or nightmares. Additionally, alcohol, recreational drugs, and withdrawal from substances can also trigger nightmares.
Diet and food intake
Although the evidence is mixed, some studies suggest that eating heavy or spicy foods before bed can lead to nightmares. Foods that affect metabolism or digestion may disrupt sleep cycles, increasing the chances of bad dreams.
Changes in sleep routine
Disruptions in sleep schedules, jet lag, or irregular sleep patterns can interfere with REM sleep, leading to more frequent nightmares.
Symptoms of nightmares
Nightmares can be distinguished from ordinary dreams by their vividness and emotional intensity. Common symptoms include:
Managing nightmares
If nightmares occur frequently or interfere with sleep, there are several approaches to managing and reducing them:
Stress management
Since stress and anxiety are common triggers for nightmares, techniques like mindfulness, meditation, deep breathing exercises, and relaxation strategies can help reduce their occurrence.
Establish a healthy sleep routine
Following a consistent sleep schedule and creating a calming bedtime routine can improve sleep quality and reduce nightmares. Limit exposure to screens, caffeine, and alcohol before bedtime.
Cognitive behavioural therapy (CBT)
CBT is an effective treatment for individuals whose nightmares are linked to anxiety, stress, or trauma. It helps reframe negative thoughts and addresses underlying emotional triggers for nightmares.
Imagery rehearsal therapy (IRT)
IRT is a technique where individuals reimagine a less frightening version of their nightmare while awake. By rehearsing this new version, the brain learns to replace disturbing dreams with more neutral or positive ones.
Address underlying medical conditions
If sleep disorders like sleep apnea or insomnia are contributing to nightmares, treating these conditions can help. In the case of sleep apnea, using a CPAP machine may reduce the frequency of nightmares.
Medication review
If nightmares are linked to medications, consult with a healthcare provider to explore alternative treatments or adjust the dosage.
When to seek help
Occasional nightmares are normal, but chronic nightmares can have a lasting impact on mental and physical health. If nightmares occur frequently, disrupt sleep, or are accompanied by symptoms of PTSD, depression, or anxiety, it may be time to seek professional help. A doctor or therapist can help identify the underlying causes and recommend appropriate treatment.

Nightmares can be distinguished from ordinary dreams by their vividness and emotional intensity. Common symptoms include:
- Emotional distress: Feelings of fear, anxiety, sadness, or anger often accompany nightmares, and these emotions may linger after waking.
- Abrupt awakening: Nightmares frequently cause people to wake suddenly, often in a state of heightened alertness or fear.
- Difficulty returning to sleep: After a nightmare, it can be challenging to calm down and fall back asleep, leading to interrupted sleep.
- Physical symptoms: Some individuals may experience sweating, rapid heart rate, or difficulty breathing after a particularly intense nightmare.
