In Bless Me Ultima. What was the significance of Antonio's Dream in Chapter 2

In his second dream of the novel, Antonio reiterates his anxieties about his future and his family. His three brothers have already determined their Marez blood and will spend their lives wandering. Antonio wants to keep the family together and support his father, but his brothers insist that he becomes a priest to make his mother happy. Again, Antonio is torn between two parents and two paths. His religious ambivalence is also highlighted in this dream when Antonio identifies the wailing in the river as first, la Llarona, a mythical figure from New Mexican folklore, and then, as Lupito’s soul. However, Antonio accepts neither the pagan explanation nor the Catholic explanation as the truth. Instead, he determines that the wailing is the presence of the river, neither Catholic nor pagan, but simply an element of nature.
