Depersonalization & derealization
Feeling unreal, or like the world is behind glass, is frightening, but it is a known experience, you are not losing your mind, and it can ease.

What are depersonalization and derealization?
Feeling cut off from yourself, the world, or both.
Depersonalization means feeling detached from your own mind, feelings or body, as if you are watching yourself from outside. Derealization means the world around you feels unreal, distant, foggy or changed. You can have one, or both together.
One key thing sets this apart: people know the feelings are not real. You know your hand is your hand. It just doesn’t feel like it. That awareness is often what makes it so upsetting.
Short moments of feeling unreal are common, for example when very tired, stressed or after a shock. It becomes a condition when the feelings last a long time or keep coming back, and cause distress.
What it can feel like
Many people struggle to put it into words. Tap any card.
Everyone describes it a little differently, and many people find it very hard to explain. If you have never been able to describe it well, you are not alone.

Many people say they feel robot-like, as if their actions happen without them. Some see other people as robot-like too.
People describe
- “I’m acting out my life, not living it.”
- “My body moves, but it isn’t me doing it.”
- “My voice sounds like a recording.”
You are still in control of what you do. It just doesn’t feel that way, which can be scary.

Emotional numbness is one of the most common parts of depersonalization. You may know you love someone, but not feel the warmth of it.
Some people hide this and seem calm or unemotional to others. That can mean the distress underneath is missed.

Some people feel they are watching themselves from outside their body, or that they are living in a dream.
This can happen for a few moments, or come and go over many years.

With derealization, the world can seem dull, hazy, lifeless or foggy, as if there is a sheet of glass between you and everything else.
It can feel like
- Familiar places seem strange or new
- Loved ones feel like strangers
- Colours or sounds seem dimmer
- The room looks like a stage set

Many people worry that something is seriously wrong with them, go over it in their head, and try hard to control the feelings. These reactions can raise anxiety and make the unreal feelings stronger.
This loop is so common that therapy for depersonalization often focuses on it. See “The worry loop” below.
Why it happens
A protective dimmer switch for overwhelming feelings.
Researchers see depersonalization as a way the mind protects itself. When feelings get too intense, it turns down the volume so a person can keep going.
Brain studies of people with PTSD back this up. In people who feel unreal, areas at the front of the brain seem to calm down the brain’s emotion centres, instead of the alarm getting louder. It is like a dimmer switch being turned down.
It has been linked with
- Accidents or natural disasters
- Being in life-threatening danger
- Growing up with a parent who had a severe mental illness
- Physical abuse
- Seeing or living through domestic violence
- The sudden death of a loved one
The exact cause is not known, and not everyone with these feelings has been through trauma. For some people it starts after a period of intense stress, a panic attack or using drugs.
What sets it off, and what eases it
Patterns from research on more than 100 people. Tap any card.
A study of 117 adults with long-lasting depersonalization looked at what started it, what made it worse, and what made it lighter. Knowing these patterns can make episodes feel less random.

The most common immediate triggers were severe stress, depression, panic, and using cannabis or hallucinogens. None of these predicted how severe it would become.
Alcohol and drugs can bring on symptoms or make them worse, so cutting down or stopping can help. Be honest with your care team about what you use.
Read more
Things that made it worse
- Negative feelings, like fear, sadness or shame
- Social situations that feel threatening
- Stress
- Unfamiliar places
Being very tired can also bring on short spells of feeling unreal.
Read more
Things that lessened it
- Comforting time with other people
- Intense feelings or strong physical sensations
- Relaxation
This fits with grounding skills, which use safe, strong sensations and calm connection to bring you back. See Coping with dissociation and Grounding & calming skills.
The worry loop
How fear of the feeling can keep it going, and how to step out.
Feeling unreal is scary, so the mind starts watching for it. You check: “Do I still feel strange?” You worry: “What if this never goes away?” That watching and worrying raises anxiety, and anxiety can make the unreal feeling stronger.
How the loop can turn
- A moment of feeling unreal
- A scary thought: “Something is badly wrong with me”
- More anxiety, and more checking of the feeling
- The feeling seems stronger, which seems to prove the scary thought
Therapy designed for depersonalization works on this loop. It helps people notice thinking traps, cut down on going over and over the feeling, ease constant self-monitoring, and slowly return to things they have been avoiding.
Small ways to loosen the loop
- Gently turn your attention outward, to a task, a person or a sound
- Keep doing things you care about, even if they feel unreal at first
- Notice the thought “I’m checking again”, then let it pass
- Set aside a short “worry time” instead of worrying all day
Links with anxiety, panic, low mood and PTSD
Feeling unreal often comes with other struggles. Tap any card.
Depersonalization often travels with other conditions. A care provider will usually check for depression, anxiety, OCD, PTSD and personality conditions too.

Panic is one of the most common things that starts long-lasting depersonalization.
Studies of people with anxiety conditions find depersonalization-derealization in about 3% to 20% of them.
For more on the body side of panic, see the Panic attacks guide.

Depression is among the most common triggers, and some studies find depersonalization in about half of people with depression.
Numbness from depression and numbness from depersonalization can feel alike. Telling a professional about both helps them see the full picture.

Experts recognise a “dissociative” form of PTSD, marked mainly by depersonalization and derealization. About 15% to 30% of people with PTSD have it.
It is more common in people who went through repeated trauma early in life, and it can come with more suicidal thoughts and more trouble in daily life.
Early research suggests people with this form may do better when trauma therapy is combined with skills for handling emotions and relationships. See the Kinds of PTSD guide.

Some physical health conditions, such as seizure disorders, are linked with these feelings. That is one reason a doctor checks for other causes first.
Feelings that happen only while using drugs or alcohol are not counted as the condition itself.
What it is not
Common fears, answered honestly. Tap any card.

People with depersonalization know their perceptions are not real. That knowing is part of what makes it so distressing.
This is different from psychosis, where a person may believe things that are not true. If you are scared of going mad, that fear is a very common part of depersonalization.

Reviews find it in around 1% of the general population, and it is more common in teens and young adults.
Many cases go unrecognised, partly because many professionals know little about it and talking therapy services do not always ask about it.

Depersonalization-derealization is classed by psychiatrists as one of the dissociative conditions, alongside dissociative amnesia and DID.
Because people often look calm on the outside, others may not realise how much they are struggling.

Without treatment it can last for years, though sometimes it fades on its own. With treatment, many people notice improvement within a few months.
Research on the long-term outlook is still limited, so be wary of anyone online who says it is “permanent” or promises a quick cure.
Getting assessed and treated
Checks first, then talking therapy. Honest about the evidence.
A mental health provider will ask detailed questions about how often it happens and how it affects you. Some use short questionnaires. They will also make sure another condition, or drugs or alcohol, are not the main cause.

Cognitive behavioural therapy (CBT) can be adapted for depersonalization. Talk therapy is described as the best treatment.
It may include
- Grounding and handling emotions
- Keeping a diary to spot triggers
- Learning what depersonalization is and why it happens
- Slowly facing things you have avoided
- Working on worry, going over things, and constant self-checking
- A plan for staying well
In a small 2025 trial in England, people who had this CBT showed bigger drops in symptoms than people who had usual care. The trial was too small to be sure, and a larger one is planned.

Eye movement desensitisation and reprocessing (EMDR) is one of the therapies used for depersonalization.
If a trauma started the feelings, working on the trauma can be part of care, once you have skills to stay steady. See the Therapies for trauma guide.

A 2023 review found only 41 treatment studies with about 300 people in total, and judged the quality and amount of research to be low for such a common condition.
That does not mean nothing helps. It means you and your provider may need to try things and adjust. For anything medical, consult with your clinical provider.
How to support someone
Believe them, stay close, and keep life going together.
Someone who feels unreal may seem fine on the outside. Inside, they may be scared and struggling to explain. You don’t have to fully understand it to help.
Read more
Try
- “That sounds really hard. I believe you.”
- “You don’t have to explain it perfectly.”
- “I’m here. Do you want company or space?”
- “Want to go for a walk with me?”
Comforting time with other people is one of the things that tends to make depersonalization lighter.
Read more
Try not to
- Ask “Do you still feel unreal?” many times a day
- Call it attention-seeking or “just stress”
- Push them to “snap out of it”
- Share scary stories from the internet
Constant checking can feed the worry loop. Gentle, ordinary connection usually helps more.

Ideas
- Go with them to new or busy places
- Help find a therapist who knows dissociation
- Invite them to everyday activities, even if they feel “not there”
- Support cutting down on alcohol and drugs
Family and friends can offer real support even without fully understanding the experience.
When and where to get help
Signs it’s time to reach out, and where to start.
It’s a good idea to talk to a professional if
- Feeling unreal keeps coming back or won’t go away
- It frightens you, or you worry about it a lot
- It is getting in the way of school, work or relationships
- It started after a trauma, or comes with flashbacks or nightmares
- You feel hopeless, or have thoughts of hurting yourself
A doctor or clinical provider is a good first step. They can check for other causes and refer you to a mental health specialist. You could say: “I keep feeling like I’m not real, or the world isn’t real, and it scares me.”
