Dreams of celebration often symbolize joy, achievement, or a significant life event. The red decorations could represent passion, love, or strong emotions, suggesting that this celebration may be tied to feelings of excitement or connection.

Talking with an old man in your dream can symbolize wisdom, guidance, or reflection on the past. This figure may represent a mentor or a part of yourself that holds valuable life lessons. Introducing him to your deceased father could indicate a desire for connection between your past and present, or perhaps a longing for approval and recognition from your father.

Overall, this dream may reflect a need to honor past relationships while celebrating new phases in your life. It might also suggest the importance of integrating wisdom from your past with your current experiences. Consider what aspects of your life are currently bringing you joy or requiring reflection, as this may help clarify the meaning behind the celebration in your dream.
