Antonio's dreams early in the novel reflect many of his fears as a young boy. He remembers his birth, he dreams about the Marez and Lunas and the pull of each way of life on him, he dreams about his brothers dragging him into a brothel. While these are remarkable dreams for a young boy, they also reveal his youth, innocence and his fears.
Later in the story, after his experiences with Ultima become more complicated and the path of his life changes, he begins to dream almost mystically, of the Golden Carp and the differences between the Catholic and the curandera way of life. His dreams begin to question his Catholic religion. This loss of innocence is key to understanding the book. Antonio's dreams change from being about fears to about the bigger questions in life that he has.
