Some narcissists are lone wolves, recluses, or hermits. They loathe human company and avoid it. All narcissists go through such phases of withdrawal, integral parts of their idealization-devaluation cycles (approach-avoidance repetition complex.) Narcissistic Personality Disorder (NPD) and Schizoid Personality Disorder share the same aetiology, psychodynamics, traits (such as grandiosity) and behavior patterns.
