Who did Santiago visit to analyze his dreams? Do you believe in dream analyze why or why not?

Once Santiago gets to Tarifa, his last stop before the city where the shopkeeper's daughter lives, he goes to see an old gypsy woman who interprets dreams, with the hope that she will help him understand his own recurring dream. When reliving the dream, just as the child is about to show Santiago the location of the treasure, Santiago wakes up. The Gypsy woman tells him that this treasure is real and that he must go to the Pyramids, an interpretation for which she charges him one-tenth of this future treasure.

The second part of the question calls for your opinion.
