Dreaming of a deceased loved one, especially a sibling, can be a powerful and emotional experience. The hug in your dream may symbolize a longing for connection and comfort, reflecting your feelings of love and loss. Talking about how she died might indicate that you are processing your grief or seeking closure regarding her passing.
This dream could also represent a desire to remember her and keep her memory alive. It may be a way for your subconscious to help you work through unresolved emotions related to her death. Consider what feelings arose during the dream and how they relate to your waking life.
If you find comfort in it, you might want to reflect on the positive memories you shared with her. It could be helpful to talk about your feelings with someone you trust or even write them down, allowing for a deeper exploration of your emotions surrounding her loss.
