Sister

A 'Sister' in a dream represents a familiar aspect of the Self. People represent characteristics within your personality, and family members represent familiar qualities. A sister, being female, specifically represents a familiar aspect of your subconscious mind -- the receptive, intuitive, inner self. Consider the qualities you associate with your sister. Those qualities are the aspects of your subconscious mind being highlighted. Pay attention to what she is doing in the dream, as this reveals how that familiar subconscious quality is currently operating in your life. When a sister shows up in your dream, identify the familiar inner quality she represents and assess whether it is serving your growth or needs attention.
