Dreams about someone you barely know can often reflect your subconscious thoughts or feelings rather than a direct connection to that person. In this case, the guy expressing his feelings for you in your dream might symbolize your own desires for attention, validation, or connection.

Seeing him communicate with your friends could indicate a longing for approval or support from those close to you regarding your relationships or romantic interests. This dream may also suggest that you are contemplating your own feelings about love and attraction, even if you haven't been consciously thinking about this person.

Consider your feelings during the dream and how they relate to your current life situation. Are you seeking new connections, or is there someone else in your life that you're interested in? Reflecting on these questions may provide further insights into your emotions and desires.
