Or HaChaim on Genesis 37:10/אור החיים על בראשית ל״ז:י׳

1 ויגער בו אביו, His father rebuked him, etc. He did so in order to remove the brothers' hatred towards him. He contradicted the interpretation of the dream by questioning how his father and mother could possibly bow down to Joseph? He implied that the sons of Jacob would not attain greatness through the Gentiles rather than through their father. Since the idea that his father would bow down to him was ludicrous, the brothers had no cause to worry. Jacob personally did not discount the dream, however.
