Here's one structure for your paper's main body that would work.
First main body paragraph: Explain what happened to Amir when he returned to Afghanistan and saved Sohrab. He barely survived the terrible beating he endured, and it is while he is recovering in the hospital that he has the dream of Baba and the bear.
Second main body paragraph: Explain the dream Amir has while in the hospital. You can quote from the novel to show the moment when Amir sees his own face in his dream.
Third main body paragraph: Explain the significance of Amir's dream, which is very symbolic. As a child, Amir had always felt weak and cowardly. He had admired his father's courage and often felt shamed by it. He had been haunted throughout his life by his betrayal of Hassan. By saving Hassan's son, Amir had found his courage and his self-respect. When he saw his face replace the face of his father in his dream, he realized he no longer lived in his father's shadow. He had wrestled his own bear (symbolically) and won.
