Dreams about being kissed, especially in a social setting like a party, can symbolize feelings of affection, desire, or connection to that person or those around you. A kiss on the neck often represents intimacy and vulnerability, suggesting that you may have deeper feelings for this friend or that you value your relationship with them.
Consider the emotions you felt during the dream and how they relate to your waking life. Are you feeling closer to this friend, or is there an aspect of your relationship that you want to explore further? This dream could be encouraging you to reflect on your feelings or to communicate more openly with them.
