Dreams involving family gatherings, celebrations, and scenarios of care can reveal a lot about your current emotional state and relationships. In your dream, the community center represents a social environment or community ties, while the celebration, whether it be Christmas or another occasion, symbolizes togetherness and shared joy.

Your reluctance to drink and party may indicate a feeling of wanting to step back from social expectations or pressures. It could suggest that you are seeking comfort in familiarity or a desire for a simpler, more nurturing environment, represented by your parents' house.

Taking your dad home due to his inebriation reflects a sense of responsibility and care for your family. This part of the dream might indicate your role as a caretaker or someone who feels the need to manage situations for the well-being of others. His singing and vomiting could symbolize the messy aspects of life or family dynamics that you may find overwhelming or difficult to deal with.

Overall, this dream could be encouraging you to consider your own needs and boundaries within your familial and social obligations. It might be worth reflecting on how you balance your responsibilities to others with your own desire for peace and contentment. If you feel overwhelmed in your waking life, this dream could be a reminder to prioritize self-care and communicate your feelings to those around you.
