In Bless Me Ultima. What was the significance of Antonio's Dream in Chapter 20

That night, Antonio dreams of his three brothers wandering in a foreign city. They beg him to release them from their wild Marez blood, but Antonio tells them that he cannot help them. He removes their livers from their bodies and places them on a fishing hook. His brothers suffer so earnestly that Antonio removes their lives from the hook and throws them into the River of the Carp. Only then are his brothers able to rest. Antonio’s dream about his three brothers highlights this realization as Antonio accepts that his brothers must be wanderers. The fact that Antonio is the source of some of their pain also demonstrates his gradual acceptance that he has lost his innocence and is capable of committing sins against others.
