How it's used

Beyond the literal meaning of sleep talking, this term is frequently used metaphorically to describe someone who is being unrealistic or saying things that make no sense. It carries a slightly playful or teasing tone when directed at someone who is clearly delusional about a situation. Unlike the literal act of talking in one's sleep, the metaphorical usage is a common way to dismiss someone's absurd claims.

Examples

Common phrases

gong2講hoi1開hau2口mung6夢

to talk in one's sleep

Common mistake

Do not confuse this with the act of dreaming itself, which is usually expressed as 發夢. While both involve sleep, 開口夢 specifically refers to the vocalization that occurs during sleep or, figuratively, to speaking nonsense while awake.
