How can you talk while you sleep?

Talking during sleep, known as somniloquy, occurs when a person vocalizes while in a state of sleep, typically during non-REM sleep. This phenomenon is often linked to factors like stress, sleep deprivation, or certain sleep disorders. It can involve mumbling or coherent speech and usually happens without the sleeper being aware of it. While generally harmless, it can be disruptive to others nearby.
