Why did Yosef have the same dream twice? And how is this different than Pharaoh who also had the same dream twice? The answer lies in understanding how each of us simultaneously lives in two realities--the spiritual and the material. This is also connected to the time-honored custom of giving "gelt" (gifts of money) to children on Chanukah.
