We were at my house and I told my granddaughter I have to leave after she goes home.
Dreams about your house often represent your own sense of identity or feelings of comfort and safety in your life. Seeing your granddaughter in the dream is a symbol of innocence and new beginnings. Telling your granddaughter you have to leave after she goes home may indicate that you feel you need to move on or let go of a certain aspect of your life, even if it's something you're attached to. It could be a signal that you need to make some kind of change or transition in your waking life, such as moving away from a certain job, relationship, or situation. Alternatively, this dream could suggest longing for independent exploration or spiritual growth.
