Sleep talking, also known as somniloquy, is a type of parasomnia, a behaviour or experience that occurs while a person is asleep. According to experts, it is a fairly common phenomenon that can range from quiet mumbling and whispers to what sounds like a complete conversation. While it can sometimes be amusing or confusing for people sharing a room, it is generally considered harmless. Sleep talking can occur during different stages of sleep, although researchers are still studying exactly why it happens.
The brain does not simply switch off when you fall asleep; different parts of the brain remain active during the various stages of sleep. A sleep psychologist explained that sleep talking may happen when areas of the brain responsible for language and speech remain active while other parts that would normally prevent a person from physically speaking are still asleep. This can result in someone talking, laughing, whispering or mumbling while remaining unaware of what they are doing.
Not every sleep talker actually uses recognisable words; much of the time, what comes out is simply mumbling, laughter or whispers. When words are spoken, they may include questions, disagreements or even profanity. In some cases, the person may appear to be having a conversation, pausing as though waiting for another person to respond. Researchers suggest that what a person says during sleep may sometimes relate to what they are dreaming about, particularly during REM sleep.
One of the biggest myths surrounding sleep talking is that you can question someone while they are asleep and get them to reveal information they would normally keep private. While researchers have found that a person who is sleep talking may sometimes respond to a question or statement, there is no scientific evidence that sleep talking can be used to make someone reveal their secrets. So, if your partner, friend or sibling says something unusual while asleep, it should not automatically be treated as a confession or reliable information.
Sleep talking is considered common and usually does not require treatment. According to information published by Graphic Online, more than two-thirds of people may experience sleep talking at some point. It is also more common among children, with researchers believing this may be linked to differences in children's sleep patterns, particularly the amount of slow-wave sleep they experience. For many people, sleep talking becomes less common as they grow older.
Although sleep talking is generally harmless, it can occur alongside other parasomnias, including sleepwalking and night terrors. If sleep talking happens frequently, disrupts your sleep or is accompanied by other unusual behaviours during the night, speaking with a healthcare professional or sleep specialist may be helpful. Another factor worth considering is sleep deprivation, as researchers have found that sleep talking and some other parasomnias can become more common when a person is overtired.
In Ghana, as elsewhere, sleep talking is a relatively common phenomenon that has sparked curiosity and concern among the public. While it is not a cause for alarm, it can be a sign of underlying issues such as sleep deprivation or other sleep disorders. By understanding the causes and implications of sleep talking, individuals can take steps to address any related issues and improve the quality of their sleep.
