What does it mean when you dream about your dead father and he seems upset and doesnt talk?

The significance of this dream depends somewhat on how much time has passed since the father's death. If the death is recent, the dream is likely to be part of the grieving process, and the effort to accept the reality of the father's death. If the death occurred long ago, something may have happened recently in the dreamer's life that triggered memories of the father's disapproval.
