Swearing in your sleep, or somniloquy, is a phenomenon that affects many people. While it can occur during both REM and non-REM sleep, it is more common during the non-REM phase and is more prevalent in men than women. Sleep talking, including swearing, can be a symptom of a parasomnia or other sleep disorder, such as REM sleep behavior disorder (RBD) or night terrors. However, it usually occurs by itself and is often harmless. In some cases, it may be a sign of a more serious underlying condition. While the exact reasons for swearing in one's sleep are not fully understood, some researchers suggest that it may be related to the threat simulation theory, which posits that dreams are simulations that prepare us for potential threats we may face while awake.

Swearing in your sleep may be linked to a parasomnia, a sleep disorder
Swearing in your sleep is a surprisingly common phenomenon. According to a 2017 research article published in the scientific journal Sleep, approximately 67% of adults have experienced sleep talking at some point in their lives, with a little over 6% of adults sleep talking on a weekly basis. While it is often harmless, in some cases, it could be linked to a parasomnia, a sleep disorder characterised by abnormal behaviours during sleep.
Parasomnias are a category of sleep disorders that involve abnormal behaviours or movements during sleep. These can include walking around, crying, or eating while asleep. One type of parasomnia is REM sleep behaviour disorder (RBD), in which individuals may act out their dreams through verbal or physical actions, such as yelling, talking, punching, or swearing in their sleep.
Swearing in sleep has been observed more commonly during non-REM sleep, with more aggressive language and louder, nastier words being associated with REM sleep. A French study found that the f-word was used over 800 times more frequently during sleep than when awake, and that sleep talkers said "no" four times as often. The study also noted that sleep talking paralleled awake talking in terms of syntax and semantics, indicating a high level of brain function during sleep.
While the exact causes of swearing in sleep are not fully understood, one theory suggests that it may be related to the "threat simulation theory". This theory, proposed by Finnish neuroscientist Antti Revonsuo, suggests that dreams serve as a form of preparation for potential threats in waking life. Swearing in sleep could be a way for the brain to express or cope with these simulated threats.
If swearing in sleep is a concern or is interfering with your sleep or those around you, it may be advisable to consult a sleep specialist or doctor. They can help determine if there is an underlying sleep disorder or health condition contributing to the behaviour and provide guidance or treatment options.

Swear words tend to occur more in non-REM sleep
Swear words are more likely to occur during non-REM sleep. This was discovered in a 2017 study, which found that the F-word was used 2.5% of the time during non-REM sleep, compared to just 0.003% of the time during waking hours. The same study also found that men were more likely to swear during sleep than women.
The reason for this disparity between REM and non-REM sleep is not yet fully understood. One theory, proposed by psychologist and dream researcher Deirdre Barrett, is that the language areas of the brain temporarily wake up during non-REM sleep, leading to the use of more complex language, including swear words. Another theory is that swearing during sleep is a form of parasomnia, a sleep disorder characterized by abnormal behaviors during sleep.
The occurrence of swearing during sleep may also be explained by the "threat simulation theory". This theory, developed by Finnish neuroscientist Antti Revonsuo, suggests that dreams serve as a way to prepare for potential threats while awake. In other words, bad dreams and nightmares are like "fire drills" that help us face our fears and avoid danger in real life. Swearing during sleep could be seen as a way to release tension and express frustration or aggression in a safe environment, which may ultimately help us deal with challenging situations in our waking lives.
While swearing during sleep is generally harmless, it can sometimes be a sign of a more serious sleep disorder or health condition. If sleep talking is interfering with your sleep or that of your bed partner, it may be a good idea to consult a sleep specialist or doctor.

Sleep talking is more common in men than women
Sleep talking, or somniloquy, is a common phenomenon where people speak during sleep, often without any memory of it. According to a study, approximately 67% of adults have experienced sleep talking at some point during their lives, with a little over 6% of adults sleep talking on a weekly basis. Sleep talking can be disruptive, especially to bed partners, and can sometimes be a sign of other sleep disorders or health issues, such as parasomnias, which are unusual behaviours that occur during sleep. Sleep talking usually occurs by itself and is most often harmless. However, in some cases, it might be a sign of a more serious sleep disorder or health condition, such as REM sleep behaviour disorder (RBD) or sleep terrors. Sleep talking can also be triggered by stress and mental health conditions, and it may run in families.
While sleep talking can occur in both men and women, it is reported to be more common in men. A study found that men are more likely to use profanity during sleep talking, with the f-word appearing 800 times more frequently than when they were awake. During non-REM sleep, which is when most swearing occurs, men were more likely to use words like "f*" and "s*", while louder and more aggressive language was observed during REM sleep in both men and women. These findings may reflect the "threat simulation theory", which suggests that dreams help train people for potential threats while they are awake.
While sleep talking is usually harmless, it is a good idea to consult a sleep specialist if it occurs suddenly or is accompanied by intense fear, screaming, or violent actions. Additionally, if sleep talking is interfering with your sleep or that of your bed partner, it may be helpful to manage stress and maintain a regular sleep schedule.

Sleep talking can run in families
Swearing in your sleep may be indicative of parasomnias, which are sleep disorders that cause abnormal behaviours during sleep. Sleep talking, or somniloquy, is one such parasomnia. It is characterised by audible expressions during sleep, ranging from incomprehensible mumbling to clear and coherent sentences. The exact cause of sleep talking is unknown, but it may be influenced by stress, mental health conditions, or genetics.
If sleep talking is disruptive to you or those around you, it is recommended to consult a sleep specialist or a doctor. They may suggest a sleep study or sleep recording to rule out other sleep disorders or underlying health conditions. While sleep talking rarely requires treatment, severe cases may benefit from addressing any underlying conditions or triggers, such as stress or mental health issues.
Additionally, managing stress and maintaining a regular sleep routine can help reduce the occurrence of sleep talking. Partners of sleep talkers can also use earplugs or white noise machines to minimise disruptions caused by nocturnal chatter. While sleep talking can be a funny or curious phenomenon, it underscores the complex brain functioning that occurs during sleep and highlights the potential for revealing insights or hidden thoughts.

Sleep talking usually occurs by itself and is harmless
Sleep talking, or somniloquy, is a common phenomenon, with approximately 67% of adults experiencing it at some point in their lives. It can manifest as anything from mumbling to full sentences and conversations. While it usually occurs by itself and is harmless, in rare cases, it may indicate a more serious sleep disorder or health condition.
Sleep talking can occur during any stage of sleep, but it tends to be more common during non-REM sleep. During this stage, the language areas of the brain may temporarily wake up, leading to sleep talking. While swearing can occur during both REM and non-REM sleep, it is more prevalent during non-REM sleep and more often observed in men than women.
The content of sleep speech can vary, but studies have found that it tends to be more negative and insulting than our awake speech. The f-word, in particular, was found to be used over 800 times more frequently during sleep than when awake. This negative language may be linked to the "threat simulation theory," which suggests that dreams are simulations that prepare us for potential threats we may encounter while awake.
While sleep talking is usually harmless, it can become a concern if it interferes with your sleep or that of those around you. Managing stress and maintaining a regular sleep routine may help reduce sleep talking. If sleep talking is severe or accompanied by fear, screaming, or violent actions, it is recommended to consult a sleep specialist or doctor to rule out any underlying sleep disorders or medical conditions.
In summary, sleep talking, including swearing in one's sleep, is a common and typically harmless occurrence. However, in some cases, it may be indicative of a more serious sleep disorder or health issue, especially if it interferes with sleep quality or is accompanied by other concerning symptoms.

Frequently asked questions
Swearing in your sleep could be due to a sleeping condition called parasomnia, specifically REM sleep behaviour disorder (RBD). However, it is usually harmless and no cause for concern.
According to a 2017 research article, approximately 67% of adults have experienced sleep talking at some point, with a little over 6% sleep talking on a weekly basis.
Sleep talking can be genetic and is thought to occur when the language areas of the brain temporarily wake up during the night. It can also be caused by stress, so managing stress may help reduce instances of sleep talking.
Parasomnia is a sleeping condition in which a person engages in abnormal behaviours during sleep, such as walking around, crying, or eating. People with parasomnia may swear in their sleep, sometimes in a hostile manner.
Sleep talking rarely requires treatment. However, if it occurs suddenly as an adult, involves intense fear, screaming, or violent actions, it may be a good idea to consult a sleep specialist.
