Hmm? Uncontrollable, built-up rage? Nah~~
I once dreamt of myself exploding once. I remembered that I screaming of my rage sleeping for fourteen-straight years. XD Well, that, and beating the crap out of every male in my school. XD
Other than that one, unfortunate dream, I've never thought of exploding because of pure anger. It's just not in my nature. I am somehow able to control myself and my emotions even in the toughest of times. :O
