Dissociation and Derealisation: Feeling Unreal

By Jess, Mental Health Writer 12 July 2026 6 min read

Feeling detached from your own body, or as if the world around you isn’t quite real, can be one of the more unsettling experiences in mental health. It’s called dissociation — and while it can be frightening, it’s common, usually not dangerous, and understandable once you know what it is.

What dissociation is

Dissociation is a sense of disconnection — from your thoughts, feelings, body, surroundings or sense of self. Two common forms:

  • Depersonalisation — feeling detached from yourself, as if you’re watching your own life from outside, or your body doesn’t feel like yours.
  • Derealisation — feeling that the world around you is unreal, dreamlike, foggy or “off.”

Brief dissociation is extremely common — most people have experienced “zoning out” or feeling spacey under stress or exhaustion.

Why it happens

Dissociation is often the mind’s way of protecting you from overwhelming stress or emotion — a kind of psychological circuit-breaker. It’s commonly linked to:

  • Anxiety and panic — it frequently accompanies panic attacks
  • Trauma and PTSD — a protective response that can persist
  • Extreme stress, exhaustion or sleep deprivation
  • Sometimes other conditions, or substances

Because it feels so strange, dissociation can itself trigger anxiety (“am I going mad?”) — you’re not; it’s a recognised, understandable response.

When it’s more of a concern

Occasional, brief dissociation under stress is usually nothing to worry about. It’s worth seeking help if it’s frequent, prolonged, distressing, or interfering with your life — especially if it’s linked to trauma or panic.

What helps

  • Grounding — engaging the senses (name what you can see, hear, touch) helps bring you back to the present.
  • Treating the underlying cause — managing anxiety, panic or trauma usually reduces dissociation.
  • Reducing stress and improving sleep — both make episodes less likely.

If dissociation is frequent or distressing, our online psychiatry service can help assess what’s behind it — book an appointment with a referral.
