When the dream is about playing competitive games I think we’re in the masculine realm – this is the realm that deals with growth through the development of agency, reasoning, judgement. I think this is also echoed in the fact the guy you’re playing is a masculine figure. Maybe places that feel competitive make you feel inferior somehow and this is something you need to work with? I think the guy attacking you may indicate that this fear of competition, of personal strength and agency overpowers you. When something attacks you in dreams and you can’t fight back it usually indicates something has power over you, you haven’t developed the necessary strength yet to relate to this potential yet. The man represents your potential for agency, strength, competition but at the moment it feels scary to you.
