After reading your OBE question I would say that the house symbolizes your mind, (your wife is allowed there, but strangers are another story) and the strangers 'invading' it are ideas that you're not perhaps sure about. When you become lucid (when did you become lucid?) you realize you get to say what's allowed and what's not allowed, and you destroy the most threatening of the ideas. These dream characters are part of you also, so that the 'male' aggressive side is actually defeated and the female 'intuitive' side continues to persist. In other words, the ideas born of intuition are gaining ground. This is supported by the idea that after you defeated the aggressive aspect the weapon became limp- because it was no longer necessary.
So I'd summarize by saying that between the intuitive vs. linear mind, the intuitive mind won, and you still 'own' your mind.

Anyway, that's what I got, I could be way off.
