Nine-year-old Julia has a reoccurring dream where she's standing on the back of a cantering horse with her arms up in the air. When she tells her mother about this dream, she's pleasantly surprised to learn that her dream isn't a farfetched fantasy but, rather, is based on something very real that she saw when she was a baby.

Julia's mother explains that what she saw in her dream is known as equestrian vaulting. It is a competitive sport celebrated all over the world, and Julia had attended such a competition when she was just two years old.
