Reality Imitates Purim Fantasy
One of the main themes of Purim involves costumes. The fun of dressing up helps us to gain an understanding of a world in which things are not what they appear to be. A world in which the opposite of what we expect to happen happens. In Pesachim 50 we learn that Rav Yosef was critically ill and had a near-death experience. When he recovers, his father asks, “What did you see when you almost departed this life?”
Rav Yosef replies “I saw an inverted world. The powerful were insignificant while the insignificant became powerful.”
