The dream may symbolize unresolved emotions and communication issues in a long-lost friendship. The friend’s house represents a familiar and comfortable place, but the fact that you haven’t seen this friend in 40 years suggests that there may be unresolved issues between the two of you. Spilling a full glass of wine in his fridge could represent a mistake or regret from the past that is still affecting your relationship. The act of cleaning up the mess with rags could symbolize your attempt to fix or make amends for this mistake. However, your friend’s lack of response while playing video games suggests that he may not be ready or willing to address these issues. The tooth flosser and the sudden flow of blood could represent the pain and hurt caused by the unresolved issues in your friendship. Your inability to control your jaw and breathe could symbolize the difficulty in expressing your emotions and communicating with your friend. The event and the bar could represent a desire for support and comfort from others, but the fact that you overtip the bartender and she gives the money back could symbolize a feeling of being rejected or not being able to find the help you need. Overall, the dream may be a reflection of your subconscious desire to resolve past issues and reconnect with a long-lost friend, but also the fear and difficulty in doing so.
