Dreams about graduation often symbolize a transition or a significant change in your life. They can reflect feelings of accomplishment, the desire for recognition, or the challenges you face in moving forward. Having celebrities like Wonyoung and Sunoo in your dream may indicate that you admire their success and wish to emulate their achievements, or they could represent aspects of yourself that you aspire to develop.

The interaction with Wonyoung's mother and the feeling of guilt about lying suggest an underlying concern about your own work ethic or progress in life. This may reflect a fear of not measuring up to expectations—either your own or those imposed by others.

The imagery of the big field and students from different schools in individual colors may signify the diversity of experiences and paths available to you. Choosing the yellow team could indicate a preference for positivity, joy, or creativity in your pursuits.

The struggle to climb the hill while holding your graduation cap and gown suggests that you may be feeling overwhelmed by expectations or responsibilities. Sitting down to rest could symbolize a need for self-care or a moment to reflect on your journey.

Receiving drinks from friends represents support and camaraderie, but your uncertainty about how to respond might indicate feelings of social pressure or insecurity in your relationships.

Overall, this dream may be urging you to acknowledge your feelings of guilt and the pressures you face, while also reminding you to lean on your friends for support as you navigate transitions in your life. Consider what steps you can take to align your actions with your goals and values, and don't hesitate to reach out for help when needed.
