How is the world of theatre opera and art in Paul's Case like the carnival in The Cask of Amontillado?

In "Paul's Case," the world of theatre, Opera, and art serves as an escape for the protagonist from his mundane reality, much like the carnival in "The Cask of Amontillado" provides an opportunity for Montresor to carry out his dark deed in a chaotic and distracting environment. Both settings offer a contrast between the characters' inner turmoil and the external extravagance surrounding them. The carnival and the world of theatre both highlight the discord between appearance and reality, emphasizing the characters' sense of alienation and isolation.
