Sometimes, listeners find the content offensive or vulgar. Sleep talkers normally speak for no more than 30 seconds per episode, but some people sleep talk many times during a night. The late-night diatribes may be exceptionally eloquent, or the words may be mumbled and hard to decipher. Sleep talking may involve simple sounds or long, involved speeches.

Half of all kids between the ages of 3 and 10 years old carry on conversations while asleep, and a small number of adults -- about 5% -- keep chit-chatting after they go to bed.

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. Sleep talking can also occur with sleepwalking and nocturnal sleep-related eating disorder( NS- RED), a condition in which a person eats while asleep. Other things that can cause sleep talking include: Certain medications Emotional stress Fever Mental health disorder Substance abuse It is a good idea to see a sleep specialist if your sleep talking occurs suddenly as an adult or if it involves intense fear, screaming, or violent actions.
