Dreaming of late father and sister

Slmz, I often dream about my late father, but before I can awake his face becomes into my husband. What could this mean?

My mother dreamt about my late sister. She was not married when she passed away, & she litterally brought us up. In the dream, my mother saw her with a baby & she was very happy. The baby looked exactly like my late sister when she was a baby. What could this mean?
