According to my pdoc this is one of my ocd traits (obsessive thoughts). I will get this bad idea and cannot stop thinking about it. Especially things that I "shouldn't" be thinking about. What really sucks is I will get stuck on whatever for days on end, just running on a loop in my head. I do the whole driving and having a terrible wreck thing, I think of hurting people in ways I would never hurt someone. Its totally uncontrollable for me. I have noticed that my anti-psychotics seem to curb them to some degree.
