As Santiago sleeps, he has three dreams. What do you think they mean to him, or symbolize in the story?

He dreams of a school of porpoises, much like the two porpoises who arrived to comfort him in his loneliness. He also dreams of his village house, and that his right arm is asleep; though in reality, this is the part of him that is still awake, waiting to be tugged by the line. Finally he dreams of the lions of his youth on the African beach and feels happy.
