I have no idea, assuming a human could act anyway possible, anyway they wanted to. SO technically yes, a person could act unable to be explained or accounted for because:
Well, when you see "special" people or you and someone notice than like: "there's the special group" or whatever, those are the people who act inexplicably all the time. I am not saying all "special" people act this way, I am just saying that if you notice they are "special," they are probably acting in an explicable way.
