Pharaoh's Dream Explained

Seven years of bumper crops are on their way
Years of plenty, endless wheat and tons of hay
Your farms will boom, there won’t be room
To store the surplus food you grow
After that, the future doesn’t look so bright
Egypt’s luck will change completely overnight
And famine’s hand will stalk the land
With food an all-time low
Noble king, there is no doubt
What your dream is all about
All these things you saw in your pajamas
Are a long-range forecast for your farmers
And I’m sure it’s crossed your mind
What it is you have to find
Find a man to lead you through the famine
With a flair for economic planning
But who this man would be I just don’t know
