Dreams involving family members can often reflect our feelings about relationships and our concerns for their well-being. In your dream, helping your daughter move may symbolize your support for her as she transitions into a new phase in her life. This could reflect your desire to be involved and helpful during significant changes.
Your sister in a wheelchair, despite not needing one, may symbolize feelings of vulnerability or a concern about her well-being. The act of goofing around suggests a playful relationship, but the sudden shift to her flipping down the hill and becoming unconscious indicates a fear of loss or harm. This could stem from your subconscious processing worries about her health or your own feelings of helplessness regarding her safety.
The hill could represent a challenge or a risk, and the act of pushing her down it might symbolize your fear of taking risks or feeling responsible for the well-being of loved ones. The fact that she flipped and was unconscious could reflect anxiety about not being able to protect those you care about or a fear of unexpected outcomes in life.
This dream has clearly evoked strong emotions in you, and it's important to acknowledge those feelings. Consider reaching out to your sister to check in on her, as this may provide you with some comfort and a sense of reassurance. Additionally, reflecting on your own feelings about change and vulnerability could help you process the emotions stirred by the dream.
