I agree with both of you..STM's post has the explanation I have tried to find since I first read here. Thanks STM.
"Beware of fact-checking the sociopath by asking other people under his or her influence. A sociopath will usually have a small group of cult-like followers who not only believe their fictional tales, but who actually internalize those fictions to the point where they rewrite their own memories to be consistent with them. If a guru-style sociopath talks about his "levitation sessions" over and over again, some of his believers will sooner or later start to form false memories in which they imagine seeing him levitate off the floor. So if you ask those people, "Did you actually ever see this person levitate?" They will enthusiastically say, "Yes!" Because in their own minds, that illusion has become something indistinguishable from a vivid memory."
It's so obvious, isn't it?
