In Ian McEwan's novel "Saturday," the author explores the complexities of human experience through the lens of sex. He presents it as a unique medium that distorts our perception of time and reality, comparable to the way dreams function in our consciousness. This biological aspect of human interaction emphasizes a depth of existence that often feels detached from our conscious lives.

McEwan likens sex to a form of hyperspace, highlighting its ability to transport individuals beyond the mundane reality of daily life. This analogy suggests that sex can evoke feelings and sensations that are far removed from the ordinary, much like the difference between water and air. Through this metaphor, the narrative invites readers to consider the profound impact of intimate connections on the human experience.
