"Alice's Adventures in Wonderland," written by Lewis Carroll in the mid-19th century, is a classic children's novel. The story follows a young girl named Alice, who, feeling bored and sleepy while sitting by a riverbank, encounters a White Rabbit. Intrigued, she follows the Rabbit down a rabbit hole and plunges into a fantastical world filled with curious creatures and whimsical adventures.

At the beginning of the book, Alice daydreams about her surroundings before spotting the flustered and animated White Rabbit. Her curiosity leads her to pursue the Rabbit, resulting in her tumbling down a deep rabbit hole. This brings her to a curious hall filled with locked doors. As she navigates this new world, Alice experiences a series of bizarre changes in size after eating and drinking mysterious substances. 

Initially frustrated by the challenges posed by her fluctuating size and the peculiar inhabitants she encounters, Alice begins to explore her surroundings. The narrative sets the tone for her whimsical and often nonsensical adventures, which characterize the entire tale.
