hanging out with an girl that used to be my neighbour in my childhood. We were never really friends. I Haven't seen her in years, at least 15 years, and she looked older. I looked at a recent picture of her and she looks exactly like in my dream. We were having a good time with other people i don't recall knowing.
Dreams about people from your past, especially those you haven't seen in a long time, often symbolize unresolved emotions or memories from that time in your life. In this case, the fact that you were never really friends with this girl from your childhood may suggest that there are unresolved feelings or experiences from that period that are resurfacing in your subconscious mind.
The fact that she looked older in the dream could symbolize the passage of time and how your memories of her have evolved over the years. The presence of other people you don't recall knowing may represent unfamiliar or new aspects of yourself or your life that are coming into play.
Overall, this dream could be prompting you to reflect on your past and how it may be influencing your present circumstances. It may also be a reminder to explore any unresolved feelings or experiences from your childhood that could be affecting your current relationships or emotions.
