CNN: Over two thirds of people will sleep talk during their lifetime.

Talking in your sleep is a parasomnia disorder called somniloquy, and experts aren’t exactly sure why it happens, said Dr. Kannan Ramar, professor of medicine at the Mayo Clinic in Rochester, Minnesota.

“Some episodes of sleep talking can last 30 seconds and transpire only once in a blue moon while others report sleep talking for longer durations and more frequently within a sleep period,” said Rebecca Robbins, sleep scientist at Brigham & Women’s Hospital and Instructor in Medicine at Harvard Medical School.

If you find your partner keeps waking up to your talking, modifying your lifestyle to include less alcohol and more hours of sleep could help, Robbins said. It’s also important to find ways to reduce stress, she added.

Ramar said people should not drink caffeine in the afternoon, and they should try and go to sleep and wake up around similar times to regulate their energy.If those don’t work, Robbins recommended people see a sleep specialist so they could conduct an overnight sleep recording to better analyze and solve the situation.
