Like a trapped animal, the narcissist is forever on the lookout: was this comment meant to demean him? Was this utterance a deliberate attack? Gradually, his mind turns into a chaotic battlefield of paranoia and ideas of reference until he loses touch with reality and retreats to his own world of fantasised and unchallenged grandiosity.
