Dreams about concerts, especially ones involving artists you admire like Taylor Swift, often symbolize your desires for joy, celebration, and connection with others. In your case, wanting to attend the concert reflects your wish for enjoyable experiences and possibly a deeper connection with your friend.

The conflict with your friend during the dream suggests feelings of frustration or disappointment in your waking life. His negative comments might represent your fears about others not supporting your passions or interests. This could indicate a need for validation or a desire for shared experiences with those close to you.

The phrase "ruined a core memory" signifies the importance you place on meaningful experiences. This might be a reminder to communicate your feelings more openly with your friend in real life, especially if you feel they are not valuing your interests.

The silent ride home could represent unresolved feelings or a disconnect in your relationship with this friend. It might be beneficial to have a conversation about your feelings and expectations regarding shared experiences, so you can prevent misunderstandings and strengthen your bond.

Overall, your dream encourages you to express your feelings and seek mutual understanding in your relationships while pursuing the joy you find in music and shared experiences.
