I am afraid I have always had this same trait.
Since I just cannot go around telling everybody what I think of them, I used to have dreams in which I would be very violent and aggressive to someone without it having any effect whatsoever.
Lately, in my dreams I am surrounded by friendly people and getting on great, which is something I tend to avoid in real life, since I do not feel very comfy around others. I hardly ever get those aggression dreams any more, so I hope it means I have moved on, if not very much further.
Another reason why I find it hard to control my fits of temper when I am alone (in public I do control them if it costs me a tummy ache) or driving, is that I feel a pull towards the adrenaline high that goes with it: it really gives me a kick (in the butt and the liver, as well, so I am trying very hard to forget about it).
Anyway, I can see it must be an astrological trait, since so many of us share it. It's great that we deflate pretty fast, otherwise we would not be fit to be around others
