Floating clouds were often described as illusory, ethereal existences that could appear in novels, movies, anime, and other fictional works to represent the temporary, invisible, or unknowable state of characters, things, or other concepts. In novels, floating clouds were often used to represent the short-lived time or the illusion of space, or as a symbolic existence. In the Harry Potter series, Harry Potter's wand was made of clouds, which became a classic scene in the novel. The image of floating clouds could also be used to express a mysterious, supernatural or fantasy atmosphere, adding a mysterious color to the work.
