Joseph tells his brothers his dream. They are in a field binding sheaves. His sheaf rises and stands upright. Their sheaves gather around it and bow down. The brothers understand immediately: "Will you indeed reign over us? Will you indeed rule over us?" (Gen 37:8). And they hated him even more for his dreams and his words.
The Torah makes no comment on whether Joseph was wise to tell them. He tells them. They hate him. This is the first of two dreams Joseph receives before leaving his father's house — both of which will take decades to fulfill, both of which will prove exact.
The irony is that Joseph cannot interpret his own: he sees the picture but not the path. The path from the dreamer in the field to the one bowing before will take a pit, a slavery, a prison, and 22 years.
