In Bless Me Ultima. What was the significance of Antonio's Dream in Chapter 7

In his dream, Antonio sees his brothers as giant figures who ask for his “saving hand.” Antonio is clearly unwilling to give up his idealized vision of his brothers, even with the suggestion that they have already lost their innocence. The fact that the giants are “dying” demonstrates that Antonio’s effort to maintain this vision of his brothers will be unsuccessful. It also suggests that his brothers will be unable to come back to their old lives in Guadalupe; the war has changed them too much, and they must move on in order to stay alive.
