REM Sleep Behavior Disorder
For most people, dreaming is purely a "mental" activity: dreams occur in the mind while the body is at rest.
Sleep talking, formally known as somniloquy, is a sleep disorder defined as talking during sleep without being aware of it. Sleep talking can involve complicated dialogues or monologues, complete gibberish or mumbling.
