Why do people talk in the sleep ?

  • Sleep talking is a sleep disorder defined as talking during sleep without being aware of it
  • Technically called “somniloquy
  • It may occur during both the REM (rapid eye movement) and non-REM sleep phases.
  • It happens during REM sleep — the stage during which we dream — it's caused by "motor breakthrough" of dream speech
  • Sleep talking may also occur during "transitory arousals," when a sleeper becomes half-awake while transitioning from one stage of non-REM sleep to another
  • Talking during any sleep stage can involve mumbles, moans, calling out, or whispering
  • Sleep-talking occurs during momentarily overlapping states of consciousness, it usually lasts just one or two seconds
  • If you stick to a regular bed time and ensure you get plenty of sleep, it can help reduce how often you sleep talk.
