Niece
A sibling's daughter — a young woman in the family whose life is one generation forward of yours.
A niece in a dream is the dream's image of a young woman in the family whose life is one generation forward of yours and whom you have known since she was small. The niece is not your daughter, and there is room for a different kind of attention — less anxious than a parent's, more committed than an outsider's. The dream brings the niece when something in your life — a younger relative becoming an adult, a piece of family continuity, an inherited responsibility from a sibling — is currently being carried in the specific kind of love that aunts and uncles give. A niece visited and listened to as a person rather than a child is the dream affirming the right adult attention. A niece overlooked because she is not your direct line is the dream noting that the wider family attention has thinned, and the young woman next door to your life is being treated as a stranger.
