"거울 나라" (Mirror Land) is a fictional realm featured in Lewis Carroll's novel "Through the Looking-Glass." It serves as a parallel universe to the real world, where everything is reversed, much like a reflection in a mirror. The story follows Alice as she steps through a looking-glass and encounters various characters and scenarios that challenge her understanding of reality. In this fantastical land, time flows differently, and the rules of logic are often turned upside down. Alice meets whimsical characters such as the Red Queen and the White Knight, each representing unique traits and ideas. The narrative explores themes of identity, transformation, and the nature of reality.
