And Joseph had a dream… and told it to his brothers. And he said… “here were the sun and the moon and eleven stars bowing down to me.” And he told it to his father and brothers. And his father was annoyed at him and said to him: “What is this dream that you’ve had? Shall we come, I and your mother and your brothers, to bow to you to the ground?” (Gen 37:5-10)
Joseph’s dream is apparently part of the Yahwist version of the Joseph story. At any rate, Jacob’s response to Joseph’s dream implies that Joseph’s mother, Rachel, is still alive. That is, the interpretation of the dream is that the sun and the moon are Joseph’s father and mother, and eleven stars his eleven brothers.
Yet this narrative, which implies that Rachel is still alive, contradicts the Elohist story of Genesis 35:16-20 which narrates her death on the road to Bethlehem, an event that has already happened! (also see #66).
