This sounds somewhat similar to ‘dynamic personality concept’ by Hlomov, which states that a developed personality has 3 parts: schizoid, borderline and narcissistic. All those parts can have different adaptation issues and if one part constantly consumes more energy and starves the others, that’s a personality type. Hlomov often uses a metaphor of 3-headed dragon, like ‘clients borderline head is now talking to therapists borderline head’. Also, in this concept any person can be in a totally borderline state in the moment, if his borderline part is taking control.
