In our world there are psychotic people that claim to hear others thoughts but it is a lie. In the knife of never letting go you can actually hear everyone's thoughts. I think the author is telling us that being psychotic is ok.
The narcissist holds themself calm, easy-going and well-composed, while driving you to the brink of sheer madness. Those who observe this from the outside, do see you as the psychotic one, and the narcissist as the unfortunate, level-headed victim. This reversed illusion was all part of the narcissist's grand plan the whole time. You were played from day one!
