This sounds like a conglomeration of interests and memories. Probably brought out by the alcohol in your system. The theme I see is the sparring people to get by in life. How are you using your sparring as a means to an end irl? Is it a healthy and procuctive means to this end? (If it's a stress release, then sure it's productive. If it's a means to money, not as much. If it's bludgeoning someone to give you what you want then not at all...just as examples). It seems you're confident in your ability to face things, but you fear that you will meet your match. Remember though that in dreams you are everyone in the dream, so this means you're facing yourself in every fight. Can you handle yourself? (Side note for clarity, is Mark Henry a heel or a hero in the dream and which is he irl at this point in the plotline?) Since Mark Henry is the opponent you can't beat, what parts of him do you identify with and how are you unable to control or handle those traits?
