Dreams in the sense of "goals" or "aspirations" also constitute a major theme. Santiago's dream of the treasure provides him with a goal; Santiago resolves to find the treasure, and by his decision to pursue this goal he is able to realize his Personal Legend. Thus, Coelho plays with the dual (and of course linked) meanings of the word "dream", as both visions during slumber and far-reaching objectives. In this sense, the message of The Alchemist could be described as follows: everyone needs a dream. The vulnerable periods of Santiago's journey are when he has no clearly defined goal. This is true when he finishes working at the crystal shop, as well as when he contemplates staying at the oasis with Fatima. Both times he thinks about desisting, but winds up carrying on unswayed.
