Two hypotheses 1. Your mother is gone, and you dream of your mother because you miss her. I hope you will be filial before your seriously ill mother's bed, which shows that you miss your mother and feel guilty. 2. Your mother is still alive, which may mean that she thinks that her mother is in poor health and may be in hospital, but during the day, she thinks that she is imagining to escape this idea, so she jumps out in her dream at night.
