"Triggering cascade" is when a seemingly minor trigger results in vastly disproportional trauma.
Total reactance characterizes Psychopaths, Borderlines, trauma victims (PTSD and CPTSD), and people with mood disorders and impulse control issues. They escalate every conflict, however minor or imaginary, to the level of nuclear, apocalyptic, all-annihilating warfare and make disproportionate use of every weapon in their arsenal simultaneously.
Trauma imprints everything and everyone involved or present in the stressful event, however tangentially. Places, people, smells, sounds, circumstances, objects, dates, and categories of the above, all get "stamped" with the traumatic experience.
