The Broken Burglar Alarm That Won't Stop

Imagine a house with a security system: the motion sensor (amygdala) detects movement and triggers the alarm, the security camera (hippocampus) records the date and time so you know when the break-in happened, and the homeowner's brain (prefrontal cortex) decides if the alarm is real or false and tells the system to stand down. During a real break-in so violent the camera gets smashed, the homeowner loses the timestamp—now every creaking floorboard feels like the burglar is back, because the broken camera cannot prove 'that was then, this is now.' The sensor stays hypersensitive (fires at shadows), the record-keeper cannot file the event as past (so the memory intrudes without context), and the decision-maker's voice gets too weak to override the alarm. The homeowner stays locked in the basement 24/7, avoiding windows and doors (avoidance) because the alarm will scream if triggered. The system is not broken—it is doing exactly what it was built to do—but it is stuck in the night of the break-in and cannot update its threat map.
