Megalomania or the "motivational constellation" occurs with self-devaluation conflicts in either hemisphere: one regarding your peers and one regarding your parents/children. These produce a stubbornness or perseverance, to the extent that you feel invincible or may elevate yourself over others.  There are different themes or nuances of this constellation, depending on the types of conflict. 
Like, I diagnose myself with a "justice megalomania", I'm easily triggered by things I find unfair to myself or others and I'm motivated to fight against these things. And my neck is a soft spot... Originating conflicts may have been comparison to my sister, and one is on behalf of my mother.
