Depersonalisation & Derealisation Disorder

1) What it is

Depersonalisation and Derealisation Disorder is a condition where someone experiences ongoing or repeated episodes of feeling:

• detached from themselves (depersonalisation), and/or
• detached from the world around them (derealisation)

It can feel like you’re not fully real, not fully “in your body,” or like life is happening through a fog or behind glass.

Depersonalisation (self feels unreal)
You might feel:

• emotionally numb
• like you’re watching yourself from outside
• disconnected from your body
• like your voice or actions don’t feel like “yours”

Derealisation (world feels unreal)
You might feel:

• the world looks flat, distant, dreamlike
• people seem unreal or unfamiliar
• time feels strange (slow/fast)
• sounds feel muffled or far away

These experiences are symptoms of anxiety and nervous-system overload — not madness. People usually know something feels “off,” which is different from psychosis.

2) What it feels like (real-life examples)

People often describe it as:

“I feel like I’m in a dream.”

“Nothing feels real.”

“I feel disconnected from my body.”

“My emotions are switched off.”

“I feel like I’m observing my life instead of living it.”

“I’m scared I’ll never feel normal again.”

“I feel numb and far away.”

Many people panic when it happens because it feels frightening and unfamiliar, and panic makes it worse.

A common cycle is:
stress/anxiety → dissociation → fear about dissociation → more anxiety → more dissociation

3) Common signs & symptoms

Symptoms can vary, but commonly include:

Depersonalisation symptoms

• feeling detached from your body
• feeling like you are outside yourself
• feeling like your thoughts don’t feel like yours
• numbness or lack of emotion
• feeling robotic or on autopilot
• altered sense of your body size/shape (sometimes)

Derealisation symptoms

• surroundings feel unreal, foggy, dreamlike
• people look unfamiliar or distant
• sounds feel strange or muffled
• colours look dull or overly intense
• time feels distorted
• feeling like there’s a “glass wall” between you and life

Associated symptoms

• anxiety or panic attacks
• intrusive “what if I’m going crazy?” thoughts
• over-focusing on sensations
• fear of being alone when it happens
• brain fog
• difficulty concentrating
• sleep problems

4) What causes it / risk factors

Depersonalisation/derealisation is often linked to:

• high anxiety and panic disorder
• trauma or C-PTSD
• chronic stress and burnout
• sensory overload
• sleep deprivation
• depression
• substance use (especially cannabis for some people)
• health anxiety (fear about sensations)

Dissociation is a protective mechanism:

the brain tries to reduce overwhelm by “switching down” emotion and sensory intensity.

5) Triggers (what can make it worse)

Common triggers include:

• panic attacks
• prolonged stress and exhaustion
• conflict or intense emotion
• overstimulation (crowds, noise, bright lights)
• lack of sleep
• caffeine and stimulants
• alcohol or drug use
• being alone with intense thoughts
• feeling trapped or unsafe
• obsessively checking “Am I real?” (self-monitoring fuels it)

6) What helps right now (fast relief tools)

The goal is to ground your nervous system and stop fear spirals.

Tool 1: 5–4–3–2–1 grounding
Name:

• 5 things you can see
• 4 you can feel
• 3 you can hear
• 2 you can smell
• 1 you can taste

This reconnects you to the present.

Tool 2: Cold water reset

• splash cold water on your face
• hold a cold object

Cold triggers the body’s calming reflex.

Tool 3: Touch + pressure

• press feet into the floor
• hold something textured
• wrap in a blanket
• push palms together

Physical pressure helps your brain re-anchor into the body.

Tool 4: Label it correctly
Say:

“This is dissociation. It’s uncomfortable, but it’s not dangerous. It will pass.”

This prevents the “I’m going crazy” panic spiral.

Tool 5: Reduce stimulation

• dim lights
• step into a quieter space
• reduce screens

Your system needs calm to recover.

7) Longer-term self-help strategies

Recovery focuses on reducing anxiety, reducing self-monitoring, and building nervous-system safety.

1) Stop checking and analysing it
A huge driver of persistence is:

“Do I feel real yet?”
Checking increases fear and keeps it going.
Replace with:

“Let it be there. It will fade.”

2) Stabilise sleep and meals
Dissociation increases when your body is depleted.
Support basics:

• consistent sleep/wake
• regular meals
• hydration
• gentle movement

3) Reduce panic sensitivity
If dissociation is linked to panic:

• practise slow exhale breathing
• practise staying calm through sensations
• learn panic cycle education

4) Grounding practice daily (not just in crisis)
Do 5 minutes daily:

• body scan
• walking outdoors
• stretching
• sensory grounding

This trains the nervous system.

5) Reduce overstimulation
Limit:

• caffeine
• excessive scrolling
• chaotic schedules

Choose more regulation activities.

8) Treatment options (what usually helps)

Treatment depends on the cause, but commonly includes:

CBT
Helps with:

• panic and anxiety reduction
• fear interpretations (“I’m going crazy”)
• reducing reassurance and checking
• managing triggers

Trauma-informed therapy
If linked to trauma:

• stabilisation and safety building
• processing trauma gradually

Grounding and nervous system work
Some people benefit from:

• somatic therapies
• mindfulness-based therapy
• nervous-system regulation support

If dissociation is severe and frequent, professional support is recommended.

9) Medication overview (plain-English)

There is no single medication specifically for depersonalisation/derealisation, but medication can help if symptoms are linked to:

• anxiety
• depression
• panic disorder

A GP/psychiatrist can guide appropriate options. Medication is often most helpful alongside therapy and lifestyle stabilisation.

10) Work, relationships & daily life tips

Work

• take short grounding breaks
• reduce multitasking (brain fog worsens it)
• hydrate and eat regularly
• try body-based grounding before meetings

Relationships
Explain simply:

“Sometimes I dissociate when stressed. I’m safe, but I feel unreal. Calm support helps.”

Ask for:

• calm presence
• gentle conversation
• grounding reminders (walk, drink water)

Daily life

• don’t avoid everything (avoidance keeps fear alive)
• keep routines predictable
• choose calming environments when possible
• reduce substance triggers

11) When to seek urgent help

Seek urgent support if:

• symptoms are constant and disabling
• you cannot function (work, sleep, care for yourself)
• you feel unsafe or suicidal
• dissociation comes with hallucinations or severe confusion
• substance use is involved and symptoms worsen quickly
