Note the alignment of the underlined words in the following verses
• Verse Gn31-10a discussing Joseph's dreams states And he dreamed yet another dream,
• and told it his brothers, and said, Behold, I have again dreamed a dream; and, behold, the sun and the moon and the eleven stars made obeisance to me.
• And he told it to his father, and to his brothers; and his father rebuked him, and said to him, What is this dream that you have dreamed? Shall I and your mother and your brothers indeed come to bow down ourselves to you to the earth?

Rashi comments on the aligned underlined passages:
• First he told it to his brothers
• Then he told it to both his brothers and also to his father

Sermonic points: Rashi paints the evolution of the family riff. First the charged emotions were only between Joseph and his brothers. Joseph sensed something was wrong. So he brought the matter up to the parental level. His father, sensing something wrong, also yelled at Joseph. However Joseph continued in his ways. He believed in himself even at the expense of his family which he subsequently loss for 13 years which he spent in slavery and a prison.

Such staging of riffs is common. People get many chances to change, repent and adjust. Joseph ignored all warnings, both at the parental and sibling level and payed for it.
