Somniloquy
（重定向自Sleeptalk）
Somniloquy or sleep-talking is a parasomnia that refers to talking aloud while asleep. It can be quite loud, ranging from simple mumbling sounds to loud shouts and long frequently inarticulate speeches, and can occur many times during a sleep cycle. As with sleepwalking and night terrors, sleeptalking usually occurs during the less-deep delta-wave NREM sleep stages or during temporary arousals therefrom.
