The phrase "what happens at night" can refer to different contexts, but generally, night is characterized by darkness due to the Earth's rotation away from the sun. At night, many natural, biological, and social phenomena occur. Animals may become active or inactive depending on species, human rest and sleep cycles engage, and various cultural or social activities often take place. Specifically, there is a notable novel titled "What Happens at Night" by Peter Cameron that explores a surreal and mysterious story of a married American couple who travel to a remote snowy European city to adopt a baby. The story unfolds mostly at night or in darkness, symbolizing deep emotional and existential experiences and the eerie atmosphere of a large empty hotel with enigmatic characters. The novel blurs reality and dream-like states with themes of mystery and emotional tension. The couple encounters strange characters and confronts their own personal and relational struggles as they try to claim their adopted baby in this unsettling setting. This theme connects "what happens at night" with psychological, mysterious, and life- altering events for the characters.
There is also a forthcoming film adaptation of this novel directed by Martin Scorsese, starring Leonardo DiCaprio and Jennifer Lawrence, to be released or in production around 2025. The film will follow the narrative of the couple in the snowy European hamlet and retain the mysterious and suspenseful elements of the book.
In a more general everyday sense, "what happens at night" outside the novel and film context includes events like people sleeping, nocturnal animals becoming active, nightlife social activities, and significant shifts in environmental conditions such as temperature drops and darkness.
