What causes you to sleep walk/talk..?!

Dreams are peculiar in the way that we can & will take on outside stimuli & incorporate them into a dream, (ever answer a phone in your dream & hear it still ring, when yer in yer dream even AFTER you've answered it, & come to find that your real phone is ringing???) If he's recoginzing you, in a dream, with fighting, I'd wonder, what is his major anxiety about you? (Fear of competition with other males over you, are you to fighting in real life, etc?) Another, thing, you'll want to do, is to not disturb him when he is in sleep state, & talking in his sleep, that way, he won't react to the stimuli that you've provided him, negatively, like punching you...Dreams are mostly plays on fears, anxiteties, & other emotions...(like dreamin' 'bout money, etc.) I wouldn't say there's a problem but maybe he does have some issues with male on male competition with you.
