I use to be afraid my anger would make me snap until I gradually realized that my self-control was equal to my anger. My fantasies of my anger being out of control also contained images of one hand holding the other in an iron grip behind my back so it couldn't get loose :-) I think only we know ourselves; often others "startle" us with what they do but I don't think I could truly surprise myself? I agree with Raynaadi that I don't think I could become that "unaware" and change my behavior from what I'm use to from myself unless I had brain damage of some sort (Alzheimer's which isn't in my family) and I don't know that I could protect myself from that no matter what so I don't worry about it.
