Sleep is a vital part of our lives, but it can sometimes be disrupted by conditions like sleep talking or sleep walking. Sleep terrors, also known as night terrors, are episodes of screaming, flailing, or intense fear during sleep. While they are generally harmless, they can be stressful and emotionally taxing, disrupting sleep patterns and causing physical injuries. Sleep terrors are a type of parasomnia, a group of sleep disorders that affect sleep movements and behaviours. They can occur during the non-rapid eye movement (NREM) stage of sleep, when the brain is partially asleep and partially awake, resulting in a state of panic or fear. Sleep terrors can affect both children and adults, with underlying causes such as fever, sleep deprivation, stress, or anxiety. Treatment options are available, including addressing underlying conditions and managing stress through therapy or relaxation techniques.

Sleep terrors (or night terrors) are a common cause of yelling in sleep
Sleep terrors, also known as night terrors, are a common cause of yelling in sleep. Sleep terrors are characterised by screaming, flailing, and experiencing intense fear while sleeping. They usually occur when an individual is partially asleep and partially awake, causing a state of panic or fear. This can result in individuals sitting up or jumping out of bed, crying, screaming, sweating, and experiencing an increased heart rate. Sleep terrors typically last between 30 seconds to a few minutes, and individuals will fall back to sleep when they are over.
Sleep terrors are considered a type of parasomnia, which are sleep disorders characterised by behaviours or events that disrupt sleep. Parasomnias occur during the latter part of the night, usually during the non-rapid eye movement (NREM) stage of sleep. They can be stressful and emotionally taxing for those experiencing them and their living companions. While sleep terrors are generally harmless, they can lead to physical injuries, such as falling out of bed or hitting nearby furniture.
Sleep terrors are more common in children, with 30% experiencing them, but they can also affect adults. They may be caused by various factors, including sleep deprivation, stress, anxiety, emotional tension, alcohol consumption, and underlying sleep disorders such as obstructive sleep apnea or periodic limb movement disorder. In some cases, sleep terrors may be genetic and run in families.
Treatment for sleep terrors is typically not necessary unless they frequently occur or interfere with an individual's life. Addressing underlying conditions or causes, such as excessive stress or anxiety, can help alleviate symptoms. Additionally, improving sleep hygiene by reducing stimulants like caffeine, establishing a regular sleep routine, and minimising sleep disruptors like playing TV or music can also help prevent sleep terror occurrences.
If sleep terrors are severe or persist, seeking professional help is recommended. A healthcare provider can diagnose sleep terrors through a detailed history, physical exam, and observations from sleeping partners or parents. While there are no specific tests for sleep talking, a doctor may order a sleep study or sleep recording if there are signs of another sleep disorder.

REM sleep behaviour disorder (RBD) can cause people to yell and act out dreams
Sleep talking and yelling can occur in any stage of sleep and usually happen by themselves. They are often harmless, but they can also be a sign of a more serious sleep disorder or health condition.
One such sleep disorder is REM sleep behaviour disorder (RBD), a complex sleep disorder affecting the brain. RBD is characterised by involuntary and often violent movements during sleep in response to vivid dreams. People with RBD may shout, grunt, or make sudden and forceful movements with their arms and legs, such as flailing, punching, and kicking. These actions can potentially cause injury to themselves or their sleeping partner. The disorder is closely associated with Lewy body dementia (LBD), Parkinson's disease, multiple system atrophy (MSA), and narcolepsy. Additionally, certain medications, substance abuse, smoking, and previous head injuries may contribute to the development of RBD.
The symptoms of RBD can vary in severity and onset, which can be either gradual or sudden. Episodes may occur occasionally or frequently, even multiple times per night, and the disorder tends to worsen over time. RBD affects about 1% of the general US population and 2% of people over 50 years old. However, the number of affected individuals is likely higher due to the difficulty in diagnosing the disorder.
RBD is a parasomnia, a type of sleep disorder characterised by behaviours or events that disrupt sleep. Parasomnias can occur during the process of falling asleep, while asleep, or when waking up. They can cause individuals to walk, talk, or make physical movements to act out their dreams. Sleep terrors, sleepwalking, and sleep paralysis are other examples of parasomnias.
If you suspect you or someone you know may have RBD or another sleep disorder, it is important to consult a healthcare provider for proper diagnosis and treatment. Keeping a sleep diary for two weeks can also help identify sleep patterns and underlying problems.

Parasomnias are sleep disorders that cause abnormal behaviours during sleep
Yelling in your sleep could be a symptom of a parasomnia—a type of sleep disorder characterised by abnormal behaviours that disrupt sleep. Parasomnias can cause a wide range of abnormal behaviours, including sleepwalking, sleep paralysis, sleep-related eating disorders, and sleep talking.
There are three main groups of parasomnias, based on the stage of sleep in which they occur. Non-rapid eye movement (non-REM) sleep parasomnias involve physical and verbal activity, such as walking, talking, eating, urinating, or initiating sexual activity during sleep. They usually occur in the first half of the night and are generally related to repeated partial awakenings. REM sleep behaviour disorder (RBD) is the most common REM-related parasomnia. People with RBD act out their dreams, often violently, through movements like punching or kicking, which can be dangerous to themselves or their bed partner. Nightmare disorder is another REM-related parasomnia, characterised by recurrent, intense nightmares accompanied by emotions such as anxiety, anger, or disgust.
The third category of parasomnias includes those that do not fit into either the non-REM or REM sleep phases. Sleep terrors, for example, happen when someone wakes up suddenly feeling scared and may scream or cry out in fright. Sleepwalking, or somnambulism, is another type of parasomnia where individuals get out of bed and move about or perform complex activities while still asleep.
Parasomnias can be treated by sleep specialists, who can help pinpoint the problem and manage symptoms, often without medication. Specialists will evaluate the sleep environment for triggers and ensure safety measures are in place. Scheduled awakenings can be used for night terrors in children, and medication may be necessary in some cases.

Catathrenia is a condition where people moan or groan in their sleep while exhaling
Yelling in your sleep could be indicative of a parasomnia, a type of sleep disorder characterised by behaviours or events that disrupt sleep. Sleep terrors, for example, usually involve frightening screams, thrashing, and kicking. REM sleep behaviour disorder (RBD) is another type of sleep disorder that causes people to shout, yell, or grunt during sleep, often violently.
Catathrenia is a rare sleep disorder where people moan or groan in their sleep while exhaling. It is distinct from other parasomnias and sleep-related breathing disorders. The groaning or moaning sounds from catathrenia usually last between two and 49 seconds, although some sources suggest that they can be as short as half a second. They occur predominantly during REM sleep, but they can also happen during non-REM sleep. The sounds are usually monotone and may be perceived as sullen, gloomy, or sexual in nature. People with catathrenia are usually unaware that they are making these sounds and sleep normally despite them. However, bed partners and family members may be disturbed by the emitted noises and concerned about their cause.
Catathrenia has been defined as a parasomnia in the International Classification of Sleep Disorders Diagnostic and Coding Manual (ICSD-2). However, there is debate about its classification. In the latest version of the ICSD, catathrenia has been reclassified from a parasomnia to a respiratory disorder. This is because it is characterised by a distinct breathing pattern, with a deep inhalation followed by a protracted exhalation, during which the moaning or groaning sounds are produced. The prevalence of catathrenia is unknown, with fewer than 100 cases reported in the literature to date.
The causes of catathrenia are uncertain, but several theories have been proposed, including dysfunctional neurons affecting respiration and small airway structures. Some people with catathrenia also report experiencing stress or anxiety in their lives, although the relationship between these factors is not yet well understood. While catathrenia is not considered life-threatening, it can affect the quality of one's sleep. Treatment options for catathrenia are also unclear, with variable results reported for methods such as Continuous Positive Airway Pressure (CPAP) therapy, sedative pharmacotherapy, oral appliances, and tonsillectomy surgeries.

Stress and lack of sleep can cause sleep-talking, which may include yelling
Sleep talking, which can include yelling, is often harmless and requires no treatment. However, it can sometimes be a symptom of a more serious sleep disorder or health condition. Sleep talking can be caused by stress and a lack of sleep. Managing stress and getting enough sleep may reduce the likelihood of sleep talking.
Sleep terrors, also known as night terrors, are a common sleep disorder that can cause people to scream, shout, or yell in their sleep. Sleep terrors can be accompanied by intense fear, crying, sweating, and a racing heart rate. They usually last between one and thirty minutes, and the person experiencing them will fall back asleep when they're over. Sleep terrors are more common in children but can also occur in adults. They are generally harmless, but they can be scary for those who witness them.
REM sleep behavior disorder (RBD) is another sleep disorder that can cause people to shout or yell in their sleep. RBD occurs during the REM stage of sleep, which is associated with dreaming. During RBD, people can physically act out their dreams, which can include yelling, shouting, kicking, and punching. This can result in injuries to the person with RBD and their bed partner.
Parasomnias are a category of sleep disorders that includes sleep terrors, sleepwalking, and sleep paralysis. They are characterised by abnormal behaviours or events that disrupt sleep. Yelling in your sleep could be a symptom of a parasomnia. Treatment is available for parasomnias to help improve sleep quality and reduce disturbances.
If you are concerned about yelling in your sleep, it may be helpful to keep a sleep diary to track your sleep patterns and identify any underlying problems. Consulting a healthcare professional can also provide guidance on managing and treating any sleep disorders or conditions.

Frequently asked questions
Yelling in your sleep can be a symptom of parasomnias, a type of sleep disorder characterised by behaviours or events that disrupt sleep. It can also be a symptom of REM sleep behaviour disorder (RBD), where people can physically act out their dreams.
Parasomnias are disruptive behaviours or events that affect your sleep. They can include sleepwalking, sleep talking, or making physical movements to act out a dream. Parasomnias can happen as you fall asleep, during sleep, or right before you wake up.
RBD is a sleep disorder characterised by vivid dreams and dream enactment behaviours such as kicking, shouting, and punching. It occurs during the REM stage of sleep when the eyes move around quickly, but all other skeletal muscle tone is lost, effectively paralysing the body. In RBD, the brainstem system that produces this paralysis is faulty, allowing people to act out their dreams physically.
Treatment options for parasomnias include addressing underlying conditions, visiting a therapist to cope with stress, improving sleep hygiene, and reducing sleep disruptors. For RBD, early identification and referral to specialist settings are vital for managing dementia risk factors and treating cognitive impairment.
If you are experiencing frequent sleep terrors or if they are causing physical injuries, disrupting your sleep health, or interfering with your daily activities, it is recommended to seek professional help. A healthcare provider can diagnose and provide treatment options, which may include addressing underlying conditions or referring you to a therapist.
