To concentrate on somebody else’s face in a dream is an attempt to understand the outward personality.
To be looking at our own face reflected in a mirror means that we may be trying to come to terms with the way we express ourselves in the ordinary, everyday world. We may also be attempting to understand our own ulterior motives. When the face is hidden or has no features, we are hiding our own power, or refusing to acknowledge our own abilities.
