Dreams about social gatherings, such as house parties, often reflect your feelings about social interactions and relationships in your waking life. The presence of security at the entrance may signify feelings of needing to protect yourself or set boundaries with others, particularly regarding your emotional or personal well-being.

Your search for your ex at the party suggests that you might be processing your past relationship and the connections that still linger in your life. This could indicate unresolved feelings or a desire to understand how your past influences your present.

Struggling with ordering an alcoholic drink while wanting to maintain your sobriety highlights a conflict within yourself. This may symbolize a temptation or challenge you're currently facing, perhaps relating to past habits or pressures that you feel in social situations. It can also represent a desire for control over your choices and your journey toward self-discipline.

Overall, this dream could be prompting you to reflect on your current relationships, the boundaries you wish to maintain, and any temptations that might challenge your personal growth. Consider what aspects of your life need more attention and how you can reinforce your commitment to your sobriety and well-being.
