What are the symptoms of talking in your sleep?
It's hard to tell if you've been talking in your own sleep. Usually, people will tell you they've heard you shout out during the night or while you were napping. Or maybe someone might complain that your sleep talking is keeping him or her up all night.
What causes sleep talking?
You might think that sleep talking occurs during dreaming. But scientists still are not sure if such chatter is linked to nighttime reveries. The talking can occur in any stage of 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.
REM sleep behavior disorder (RBD) and sleep terrors are two types of sleep disorders that cause some people to shout during sleep. Sleep terrors, also called night terrors, usually involve frightening screams, thrashing, and kicking. It's hard to wake someone having a sleep terror. Children with sleep terrors usually sleep talk and sleepwalk.
People with RBD yell, shout, grunt, and act out their dreams, often violently.
