Daughters appear in our dreams for many reasons and the majority of dreams they are in some sort of danger. Could it suggest you are instinctively picking up on them or this is something unconscous within you. For example negative themes such as kidnapping or drowning could suggest unconscious fears of losing them or some sort of weakness you are seeing within them. Mothers may also see their daughters as an expression of them in the past, special bonds and memories. Fathers who dream of their daughters relate to their unconsous feelings, the feminine or receptive side. When they are drowning it shows an emotional upheaval they might be going though. A daughter that dies is a positive symbol of a rebirth and transformation. A daughter that gets married suggest a union or bonding of some sort in her life.
