Death of a Child
According to AstroSwami the meaning of your Dream is:
Although a parent's dream of a child's death is overwhelming, in actuality it is not a sign of something terrible to come. Rather, it is an indication that our child is reaching or is just past a stage in his or her life, and our minds are mourning or saying goodbye to the young child of the past. Did your child just give up a bottle, begin to talk or is about to enter high school? Any of these might bring a dream of this kind, allowing your mind to say goodbye to the past and welcome the future.
