my sister waved to me and didn't hug me like she usually does, and walked away, in my clothes, thrown together, mismatched.
Dreams often reflect our emotions, relationships, and subconscious thoughts. In your dream, the imagery of your sister waving instead of hugging you may symbolize a feeling of distance or change in your relationship with her. The hug, typically a sign of closeness and affection, not happening could suggest a sense of emotional disconnect or perhaps a desire for deeper connection that feels unfulfilled.
Your sister wearing your clothes, especially if they appeared mismatched or thrown together, may indicate feelings of vulnerability or insecurity regarding how you present yourself, or how your identity is perceived by others. It might also suggest a conflict between your sense of self and how others see you, or perhaps you're feeling overshadowed or challenged by someone close to you.
Overall, this dream could reflect your concerns about your relational dynamics with your sister, possible changes in your emotional bond, and personal feelings about identity and self-expression during this period of your life. Consider your current circumstances and feelings towards your sister, as they may help reveal the deeper meanings of the dream.
