Dreams involving famous figures and symbols can often reflect your subconscious thoughts and feelings. In your dream, being at a table with renowned pianists suggests that you may be seeking recognition or validation in your own musical abilities or creative pursuits. The silver coins could symbolize value, wealth, or an acknowledgment of talent, particularly connected to classical music and its greats like Mozart and Liszt.

The act of putting the coins in their mouths, especially with the gagging, might signify the struggle to express or contain something valuable within you. This could reflect a feeling of pressure to perform or live up to high standards, possibly influenced by your admiration for these musicians. Cortot looking you in the eyes could indicate a personal connection or challenge, as if he is urging you to confront your own feelings about your capabilities or aspirations.

Overall, this dream may encourage you to explore your relationship with your own talents and the expectations you place on yourself. Consider what the coins represent to you and how you can channel your passion for music in a way that feels authentic and fulfilling, rather than feeling constrained by the expectations of others.
