Hypervigilance, dissociation and shutdown

When the nervous system stays braced, or switches off altogether.

  • Card 1

    Hypervigilance is a state of heightened alertness — scanning rooms, reading faces, anticipating problems before they happen. It often develops when danger was unpredictable, so staying alert felt like the only way to stay safe.

  • Card 2

    Hypervigilance can look like

    • Struggling to relax even when nothing is currently wrong
    • Startling easily at sudden noise or movement
    • Constantly assessing other people's moods
    • Difficulty sleeping because 'switching off' feels unsafe
  • Card 3

    Dissociation and shutdown sit at the other end of the spectrum — a kind of protective disconnection from feelings, body sensations, memory or surroundings, which can develop when fighting or fleeing wasn't possible.

  • Card 4

    Dissociation and shutdown can look like

    • Feeling foggy, distant, or like you're watching yourself from outside
    • Losing time, or gaps in memory for ordinary events
    • Feeling numb or 'switched off' during emotionally significant moments
    • A heavy, weighted stillness, or difficulty moving or speaking
    The Dissociation and Window of Tolerance modules go into more depth on these states and gentle ways of working with them.
