Ein Yaakov (Glick Edition)
R. Jochanan said: "Three dreams are bound to be realized: that which is dreamed in the morning; that which is dreamed by one's neighbor: and a dream which is interpreted within a dream." Some add to this "A dream that is dreamed by the same person twice": as it is written (Gen. 41, 32.) And for that the dream was doubled unto Pharaoh.
