What is the name of the song Alice sings when she first enters Wonderland?

Alice sings “In a World of My Own” at the beginning of the 1951 film, just before she follows the White Rabbit into Wonderland.

The song introduces Alice’s imagination before the fantasy adventure fully begins. Sitting beside the river with her cat Dinah, she imagines a world where ordinary rules are reversed and animals can behave like people. Its lyrics establish the central idea that Wonderland resembles the curious private world Alice has been imagining.

A common mix-up is “All in the Golden Afternoon,” which is sung by the flowers after Alice has already entered Wonderland. “Very Good Advice” comes later, after Alice has grown frustrated and confused by her experiences. “Alice in Wonderland” is the film’s main theme, not the song Alice performs in this opening scene.

The song was written by Sammy Fain and Bob Hilliard. Its melody was originally associated with an unused song, “Beyond the Laughing Sky,” before being reshaped for Alice’s opening number.
