Yaakov is on the lam as he flees from his vengeful brother Esav. He stops for the night, arranges himself a camp area and he goes to sleep. It is there we learn of Yaakov's lofty dream about angels ascending and descending a ladder to and from Shamayim.
My question is this: What do you normally dream about? There are a few dreamers in Bereishit and we learn from them all.
Yaakov dreamt of heavenly matters that would affect the trajectory of his whole life. Yoseif dreamt of both heavenly and earthly matters.
To be a successful Jew, one must be a dreamer. The key is to dream of the right things.
