Dreams about social gatherings, particularly with familiar faces, often reflect our thoughts and feelings about relationships and connections in our waking life. In your dream, the presence of your family and friends suggests a desire for comfort and acceptance within your social circle.

The interaction with your ex-best friend, where you share an intimate moment, may indicate unresolved feelings or a longing for a deeper connection. It could symbolize a wish to rekindle a friendship or explore romantic feelings that you may have towards her. The act of kissing and the subsequent blushing suggest vulnerability and a desire for closeness, highlighting your feelings of affection and possibly attraction.

The appearance of the girl from high school and your brother's interruption could represent feelings of judgment or concern about how others perceive your relationships. This might point to your own anxieties about being open with your feelings in social situations.

The scene with the girl getting arrested may reflect your feelings about justice or fairness in your relationships. It could symbolize a wish to see certain people face consequences for their actions, particularly if they have previously hurt you or your friends.

Finally, the full moon and the view of New York City signify a time of reflection and potential new beginnings. The moon often symbolizes intuition and emotions, and in this context, it suggests that you are contemplating your feelings and considering taking a step towards expressing them, such as asking your ex-bestie out.

Overall, this dream might be encouraging you to explore your feelings and consider how you want to approach your relationships. It may be a good time to reflect on your emotions and perhaps take a leap of faith in pursuing a deeper connection with your ex-best friend.
