Article summary

Dissociation is a disconnection between things that are normally joined up: thoughts, feelings, memories, the sense of who you are, and the sense that the world is real. When a young person dissociates, one or more of those threads comes loose. Unlike a meltdown, it rarely looks like obvious distress. It usually shows as a sudden absence: a glazed look, a long pause, or a feeling that your child has briefly checked out or gone blank.

Key takeaways

  • Dissociation is the mind and body's protective response to feeling overwhelmed, often by trauma.
  • It runs on a spectrum: from everyday daydreaming, which is normal, through trauma-related dissociation, to the rare dissociative disorders.
  • It often looks like spacing out, feeling unreal or detached, or gaps in memory, rather than obvious distress, so it's easy to miss.
  • Take it seriously when it's frequent, distressing, or getting in the way of daily life; persistent dissociation is linked to self-harm.
  • With safe, paced, trauma-informed support, young people genuinely recover. The nervous system can learn that the danger has passed.
