Sleep talking is a similar parasomnia to sleepwalking, although unlike sleepwalking it can occur during either REM or non-REM sleep. Many people shave spoken in their sleep at least once, and it is believed to occur annually in about half of children and 5 percent of adults. A sleeping person may speak in full sentences, disconnected words, or complete gibberish. Sleep talking generally does not affect the speaker’s sleep quality, although, like sleepwalking, it may disturb their partners. Sleep talking may also be a symptom of another sleep disorder, such as night terrors. Children are more likely than adults to talk in their sleep, and the disorder appears to have a strong genetic component as it has been found to run in families.
