Depersonalization is the feeling of being detached from yourself: as if you are watching your life from the outside, your body or thoughts don’t quite belong to you, or you are going through the motions like a robot. It is frightening, and many people who feel it for the first time fear they are “going crazy”. In almost every case, they are not. Brief episodes are very common, especially during anxiety, panic, exhaustion or after cannabis, and they usually pass. Only around 1 in 100 people have the persistent form, depersonalization-derealization disorder. And research suggests one thing keeps the feeling going more than anything else: being afraid of it.
This article explains what depersonalization is, how it differs from derealization, why it happens, why it sometimes sticks, and what the evidence says actually helps.
What depersonalization feels like
People describe it in strikingly similar ways. According to the MSD Manual’s clinical overview, people with depersonalization feel “like an outside observer of their life”, and many say they feel “unreal or like a robot or automaton”. The same overview describes:
- Feeling as if you have no control over what you do or say, as if you are on autopilot.
- Feeling emotionally and physically numb, or detached, with little emotion.
- Feeling disconnected from your memories, and unable to recall them clearly.
The important part is that you know something feels off. You don’t believe you have actually become a robot. You notice that you feel like one, and that noticing is often what makes it so distressing.
Depersonalization vs derealization (and dissociation)
The two often come together, and the research usually discusses them as a pair (DP/DR). They are experiences of unreality “in, respectively, one’s sense of self and the outside world”.
| Depersonalization | Derealization | |
|---|---|---|
| What feels unreal | You: your self, body, thoughts or feelings | The world around you |
| How people describe it | “I’m watching myself from outside”, “I’m on autopilot” | “Like being in a dream or a fog”, “as if there’s a glass wall between me and everything” |
| The world may seem | Normal, but you feel absent from it | “Lifeless, colorless, or artificial” (MSD Manual) |
Dissociation is the broader term for experiences in which your usual sense of connection to yourself, your surroundings or your memories is disrupted. Depersonalization and derealization are forms of it, and their persistent form, depersonalization-derealization disorder, is classified among the dissociative disorders. So depersonalization is a kind of dissociation, but dissociation covers more than depersonalization.
How common is it? Very, as a passing experience
This is the most reassuring part of the research, and it rarely makes it onto the pages that come up first in search.
A systematic review from the Institute of Psychiatry in London found that brief episodes of depersonalization or derealization are common in the general population, with lifetime rates between 26% and 74% across studies, and between 31% and 66% at the time of a traumatic event. The ranges are wide because studies define and measure the experience differently. But even the lowest figure means roughly one in four people has felt it at some point.
The persistent disorder is much rarer. A 2023 systematic review of 23 studies put depersonalization-derealization disorder at “around 1%” of the general population, more common in adolescents and young adults. A recent analysis of a large US national survey found a similar figure: 0.9% had clinically significant symptoms in the past month.
In other words, feeling unreal is a common human experience. Having it become a long-term problem is uncommon.
Why it happens: anxiety, panic, stress and trauma
Depersonalization is closely tied to anxiety, and especially to panic. In the London review, rates among people with panic disorder ranged from 7.8% to 82.6% across studies. Feeling detached or unreal during a panic attack is a recognised part of how panic can feel. It is not a sign that you are losing your mind. If panic is part of the picture for you, our guide to breathing exercises for panic attacks covers what you can do in the moment.
Other common triggers, according to the MSD Manual, include severe stress (personal, financial or work-related), depression, anxiety and drug use. There is also a link with trauma: the 2023 review found the disorder far more often in people who had experienced interpersonal abuse, at 25% to 53.8% in those studies. That does not mean everyone who feels unreal has been through trauma. Many people haven’t. But if trauma is part of your story, it is worth knowing about the connection, and a trauma-informed therapist can help.
Why it sticks: the fear-of-the-feeling loop
If most episodes pass, why do some people get stuck with depersonalization for months or years? The leading psychological explanation is a cognitive-behavioural model developed by Elaine Hunter and colleagues at the Institute of Psychiatry. It is a model, not a proven mechanism, but it fits what many people describe and it is the basis for the treatment with the most research behind it.
It works like this:
- A normal, passing episode happens, often during stress, panic, exhaustion or a bad high.
- You interpret it as a catastrophe. “I’m going mad.” “I’ve damaged my brain.” “This will never go away.” The MSD Manual notes that some people fear they have irreversible brain damage or psychosis.
- That fear raises your anxiety, and anxiety is one of the main drivers of depersonalization. So the feeling gets stronger.
- You start checking and avoiding. You test whether you still feel unreal, look in mirrors, read about symptoms, avoid places where it got bad. The model says these habits keep your attention locked on the feeling and stop you from discovering that the feared catastrophe isn’t happening.
The loop then feeds itself. The practical implication is counterintuitive but important: trying hard to make the feeling go away, and constantly checking whether it has, tends to keep it around. What helps is changing how you relate to it.
Depersonalization after cannabis
Many people first feel depersonalized during or after using weed, and it can be terrifying to be stuck with the feeling once the high is over. The MSD Manual lists marijuana, ketamine and hallucinogens among the drugs that can trigger it.
The best data come from one large survey of 394 adults with chronic depersonalization, run at Mount Sinai in New York. It compared 196 people whose depersonalization began with drug use with 198 whose didn’t. Cannabis and hallucinogens were the most common triggers, followed by ecstasy. Three findings stand out:
- Most of those people had used drugs only modestly before it started, and most never used again afterwards.
- Drug-triggered and non-drug-triggered depersonalization looked the same in symptoms and impact. The researchers concluded it is the same condition, whatever starts it.
- The drug-triggered group improved more over time than the other group.
It was a self-selected online sample, so it can’t say how often this happens to cannabis users in general. But it is reassuring on one point: drug-triggered depersonalization is not a separate, permanent kind of damage. It responds to the same understanding as any other kind. If it persists after the drug has worn off, it is worth seeing a doctor, and avoiding the drug that triggered it is a sensible step.
Grounding techniques: what they can and can’t do
Grounding techniques are widely taught for depersonalization, and many people find them useful in the moment. They work by bringing your attention to concrete, present-moment input: what you can see, hear and touch. You can find simple versions, like the 5-4-3-2-1 exercise, in our guide to coping skills for anxiety.
It is worth being honest, though: there are no clinical trials testing grounding as a treatment for depersonalization. And the fear-of-the-feeling model suggests a trap to avoid. If you use grounding as a test (“Do I feel real yet? No? Try harder”), it can turn into one more form of checking. Used well, grounding is less about making the feeling disappear and more about getting on with life while it is there:
- Engage with the world, not the symptom. Talk to someone, cook, walk, do a task that uses your hands. Notice what is around you because it is interesting, not to measure how real it feels.
- Bring your arousal down. Because anxiety drives depersonalization, things that calm the body, such as slow breathing, sleep and movement, can help indirectly. Our guide to nervous system regulation separates the practices with real evidence from the hype.
- Label it, then let it be. “This is depersonalization. It feels awful, but it is a common, known experience, and I don’t need to fix it right now.”
- Stop researching it. Reading about symptoms late at night is one of the most common ways the loop keeps going.
Treatment: what the evidence actually shows
This is where the honest picture differs most from the treatment-centre pages: there is no treatment yet with strong proof behind it, though there is a promising one.
Medication. A 2013 systematic review using Cochrane methods found just four randomised trials, with 180 participants in total: two of lamotrigine, one of fluoxetine and one of biofeedback. One lamotrigine trial found a benefit and the other didn’t. Fluoxetine and biofeedback did no better than the control. The MSD Manual summarises it plainly: various medications have been used, “but none have clearly demonstrable efficacy”. Medication can still be useful for anxiety or depression that comes with depersonalization. That is a conversation to have with a doctor.
The wider evidence base. A 2024 systematic review gathered every published treatment study it could find, of any type. It found 41 studies covering just 300 people, most of them case reports, and judged their quality “generally low”. The authors ended with “an urgent call for more high-quality research”.
CBT designed for depersonalization. The most promising approach is cognitive behavioural therapy built on the model above. It helps people reinterpret their symptoms as non-threatening and cut back on avoidance, safety behaviours and symptom-checking. The research so far:
| Study | Who | What it found | Limits |
|---|---|---|---|
| Hunter et al., 2005 | 21 people with the disorder | Significant improvement after therapy and at 6 months. 29% no longer met the criteria for the disorder. | Small, no control group |
| Hunter et al., 2023 | 36 people at an NHS specialist clinic | Depersonalization, depression and anxiety scores improved during treatment, with medium effect sizes. Each person’s time on the waiting list served as their own comparison. | Not randomised, small |
| Hunter et al., 2025 | 30 people, randomised to CBT or usual care | Symptom scores fell on average by 16.9 points with CBT vs 5.5 with usual care. | A feasibility trial, not designed to prove CBT works. Only 63% completed follow-up. |
Taken together, this is encouraging but not conclusive. The researchers themselves call for a full-scale trial. If you are looking for help, a therapist who understands depersonalization specifically, and who works with the fear-of-the-feeling model, is the best-supported option available today. Many people also recover with time: the MSD Manual notes that “complete recovery is possible for many patients”, though for some it becomes long-lasting.
If you want support understanding what is happening and practising a different relationship with the feeling day to day, aidx.ai, an AI coaching and therapy service, can help you reflect on what you notice, catch the catastrophic thoughts that feed the loop, and work through the anxiety around it at your own pace. It is AI, not a clinician. It does not diagnose or treat depersonalization disorder, and it is not a substitute for a medical assessment.
When to see a doctor
Brief episodes during stress or panic that pass on their own don’t usually need medical attention. It is worth seeing a doctor if:
- It persists or keeps coming back for weeks, or it is affecting your work, relationships or daily life.
- It started after drug use and hasn’t settled once the drug has worn off.
- It comes with neurological symptoms, such as seizure-like episodes, losing time, confusion, a severe headache, or new problems with vision, speech or movement. Seizures are one of the medical causes a doctor will want to rule out, and the MSD Manual notes that assessment can include a general medical examination, and sometimes MRI or EEG.
- It comes with low mood, hopelessness or thoughts of harming yourself. Please seek help straight away (crisis lines are listed at the end of this article).
A doctor can check for other causes, and a mental health professional can assess whether it fits depersonalization-derealization disorder. The diagnosis requires that the experiences are persistent or recurrent, cause significant distress or impairment, aren’t better explained by something else, and occur while reality testing stays intact.
Common questions
Am I going crazy?
Almost certainly not. The key sign is that you know the feeling isn’t real. You feel as if you are in a dream, but you know you aren’t. Doctors call this intact reality testing, and it is part of the diagnostic criteria for depersonalization-derealization disorder. It is what separates depersonalization from psychosis, where people lose that awareness. Fearing that you are going crazy is a typical reaction to depersonalization, and, as the cognitive model above describes, it is part of what keeps the feeling going.
How long does depersonalization last?
It varies a lot. According to the MSD Manual, episodes “may last for only hours or days or for weeks, months, or sometimes years”. Most passing episodes, like those during a panic attack, are short. When it lasts, the fear-of-the-feeling loop is often part of why, which is also why it can change.
How long does depersonalization from weed last?
There is no reliable timeline, and anyone who gives you one is guessing. In the survey of 394 adults, people whose depersonalization started with drugs improved more over time than those whose didn’t. If it continues after the drug has worn off, stop using it and talk to a doctor.
How do I get rid of depersonalization quickly?
The honest answer is that fighting it hard tends to backfire. Urgently trying to make it stop, and checking every few minutes whether it has, keeps your attention on it and your anxiety up, which is what feeds it. What tends to help more is calming your body, getting absorbed in something real, and letting the feeling be there without treating it as an emergency. That is slower than people hope, but it is the approach the evidence supports.
What makes depersonalization worse?
Stress, anxiety and panic, poor sleep, exhaustion and drugs such as cannabis are common triggers. So are the habits the cognitive model describes: constantly monitoring the feeling, avoiding situations, and searching for reassurance online.
Is depersonalization the same as feeling numb?
They overlap. Emotional numbness is one of the ways depersonalization can show up, but numbness can also happen on its own, for example with depression or burnout, which we cover in feeling lost, numb or stuck. Some people with depersonalization also find it hard to recognise or describe their emotions, a trait called alexithymia.
How can I help someone with depersonalization?
You can’t snap someone out of it, and trying to (“just focus, you’re fine”) can add pressure. What helps more: stay calm, tell them that what they are feeling is common and that it passes for many people, help them do something ordinary and absorbing with you, and avoid quizzing them about how real they feel. If it persists, encourage them to see a doctor or a therapist who knows about depersonalization.
Is there online therapy for depersonalization?
Yes. CBT can be delivered online or by video by a qualified therapist, and some therapists specialise in depersonalization. When choosing one, it is worth asking whether they are familiar with depersonalization-derealization disorder and the cognitive-behavioural approach to it, since the condition is under-recognised and not every therapist knows it well.
