My therapist is deeply into dreamwork, with a Jungian perspective. She has shared that the people in our dreams reflect aspects of ourselves. Perhaps you would find it healing to consider those dream-people as parts of yourself, that it is within you to give yourself some mothering, to befriend both the mature, caring, but preoccupied side (your LCM in the dream), which the part of you tied up in outside issues, and free her up to focus on your healing, bringing along the immature daughter part, and the middle/teenaged type part (represented by you in the dream) who feels so wanting and upset.
