It typically refers to the weather, indicating that the sky becomes covered with clouds or that it becomes gloomy, aligning with a metaphorical transition from clarity to obscurity. Beyond the literal, "cloud over" is also employed metaphorically to express a change in someone's emotional state, usually signaling that someone becomes pensive, worried, or glum. The usage of this phrasal verb is vivid and evocative, making it a popular choice in both creative and colloquial speech when describing an emotional or atmospheric change that parallels the natural phenomenon of cloud formation.
