In Parshas Vayeishev, Yosef's brothers refer to him as "Baal Hachalomot". Translations can range from the extravagant, "Master of  Dreams" to the derisive, "Dreamer". But Yosef is indeed defined by his dreams. The era of direct interaction with G-d has temporarily ended. Of all the sons, Yosef is the one chosen to receive messages, and they are cryptic visions filled with symbols, suns, stars, moons, birds, cows, wheat, that are ripe with potent symbolism. His father Yaakov had been the first to communicate with G-d more heavily through symbols, a ladder, animals in the field, but he had received verbal messages of plain meaning. Yosef does not appear to. Though Yosef is defined by dreams, he only receives two of his own, as a teenager. The latter two sets of dreams are those of others, Egyptian ministers and Pharaoh, interpreted by him. These dreams are divided into three pairs of two. Each dream has a counterpart. Yosef first dreams two dreams.
