Dissociative experiences, like depersonalisation, are linked to sleep disturbances, not just trauma. This study found a strong correlation between dissociative symptoms and sleep experiences, even after accounting for response bias.

Area of Science:

  • Psychiatry
  • Sleep Medicine
  • Psychology

Context:

  • A common belief links dissociative experiences to trauma.
  • This study critically evaluates the trauma etiology theory.
  • An alternative hypothesis suggests a labile sleep-wake rhythm as a cause.

Purpose:

  • To critically evaluate the trauma etiology of dissociative experiences.
  • To investigate the association between dissociative experiences and sleep-wake rhythm.
  • To test the hypothesis that dissociative experiences stem from sleep disturbances.

Summary:

  • Two studies explored the relationship between dissociative experiences (Dissociative Experience Scale) and sleep experiences (Iowa Sleep Experiences Survey).
  • A significant correlation was found between dissociative symptoms and sleep experiences, including nightmares and strange dreams.

  • This association remained robust even when controlling for response bias, suggesting it is not an artifact.

    • Impact:

    • Challenges the widespread view of trauma as the sole cause of dissociative symptoms.
    • Provides evidence for a link between sleep disturbances and dissociative experiences.
    • Suggests that sleep-wake rhythm regulation may be a crucial factor in understanding and treating dissociative disorders.
