A dream

Just awoke from a strange and memorable dream. I´m with my brothers on some beach wth heavy waves, and we´re playing a game--very competitive--which involves diving into the breaking surf to collect floating colonial Lego men (there may also be other Lego bits--perhaps a wrecked Lego cargo ship--but only the white-crossbelted figures count).
At one point, incongruously, my round is interrupted by the danger of a semitruck rolling in with the tide immediately after Dan´s turn--which is momentarily scary as my view of him getting out of the water is blocked by the truck. But it soon vanishes, enabling the game to continue.
The competition is hot,and the tide is intensifying when a kid about our age pproaches, saying something about a beach rule which dictates (oh blast, it´s getting hazy!) something preventing our game--to me it seems an absurd rule which need not be followed--so we´re polite and nod. He goes back about his business.
The rule is some kind ofthing requiring participation in something which should be strictly voluntary, and in my opinion would only be enforced by wankers, but the kid is insistent, continually interrupting our game, which starts to annoy me. He´s one of those rule-sucking holier-than-thou social-antactivists whom I just love.
At some point I realize I´ve been swimming naked.
The kid gets angry, demanding we join the rule-bound whatever, and acts tough as if trying to provoke a fight. So I respond, stepping up saying,
"Alright toughguy, let´s do this. Plant one," I offer my chin, "first one´s on me."
He is ruffled, but not yet surrendering.
"Fuck it, you want some?" I drop my towel and go after him, swinging free. Unprepared as bullies are for any kind of active defense (especially when the opponent is naked), he backs down, dropping level with his cronies.
"You boys want some too?"
They cannot touch us. Even in the unlikely event of a melee, if they got through my front line, I´d simply summon my brothers to the fray and turn it messy.
One guy who reminds me of a kid I know from middle-school actually has the nerve to advance, but I quickly dissuade him, and the situation is over as I wake up nearly laughing.
Aside from the obvious friendly competition and cocksure behavior, I have no clue as to the meaning of this dream. Why was I unable to recognize the absurd circumstance as a dream and become lucid? What does it all mean in Jung/Freud interpretations? Perhaps further thought may shed some ligh, because it was quite vivid and though has, of course, faded, it still sits strikingly in mind. Perhaps you have an interpretation to offer?
