Genesis 41:4
And the cows that were ugly and gaunt ate up the seven sleek, fat cows. Then Pharaoh woke up. The consumption of the fat cows by the gaunt cows is the dream's central image — the years of scarcity consume the years of abundance. The waking at this point is the natural response to a disturbing dream. The application: the dream that wakes you up is often the dream that most demands interpretation.
