Dreaming about someone you haven't seen or talked to in a long time can be significant. It often reflects unresolved feelings or memories associated with that person or the time you spent together. In your dream, the conversation about your lives suggests a desire for connection or reflection on your past experiences. Your closeness to her sister in the dream might indicate that you are looking for support or comfort in your current life, or it could symbolize the importance of relationships that have influenced you.

This dream might also signal a longing to reconnect with aspects of yourself or your past that you associate with that person. Consider what this individual represents to you and if there are any lessons or feelings you need to revisit. It could be valuable to reach out to this person or reflect on how your past relationships shape your current life.
