The adolescent who feared abandonment as a child has dissembled through crypsis and has dissimulated through camouflage and mimicry.
Increased arousal causes the part of the adolescent that has survived through crypsis to surface as unconditioned responses, that is delusions, while the part of the adolescent that has been inhibited irretrievably, that is, deactivated, is unable to take ownership for the increased arousal, which is therefore experienced as coming from the outside world.
The precise timing of these intensifications is a function of external events that feel arousing to the adolescent.
