If you are dreaming of your own daughter, ask yourself if there is a current issue with her that you are concerned about. If not – and especially if she is no longer under your roof – then your daughter may be standing in for some aspect of yourself that is like your daughter. What part of you do you see in her the most? That is most likely what she represents in your dream.
If you don’t have a daughter in real life, then your daughter in your dream is most likely some project, some relationship, or even some part of you that is still growing and developing, something YOU are responsible for.
