The feeling of not being real is called depersonalization. If the world around you feels unreal instead, that’s called derealization. These two experiences often occur together, and when they’re persistent or recurring, the clinical term is depersonalization-derealization disorder (DPDR). Brief episodes are surprisingly common, but for some people they last weeks, months, or even years.
What Depersonalization and Derealization Feel Like
Depersonalization and derealization are related but distinct experiences. Depersonalization is a sense of detachment from yourself: your thoughts, feelings, and body don’t feel like they belong to you. People often describe it as watching themselves from outside their own body, like observing a character in a movie. You might push a grocery cart, pick items off shelves, and go through checkout while feeling like someone else is doing all of it. You might look in a mirror and not recognize the face staring back.
Derealization is the flip side. Instead of feeling detached from yourself, you feel disconnected from the world around you. People, objects, and surroundings can seem foggy, flat, or artificial, like looking through a pane of glass or watching everything on a screen. Colors may look washed out. Distances may seem distorted. Familiar places can feel completely foreign.
Most people experience both at the same time, which is why clinicians group them together. The episodes tend to wax and wane in intensity. Some last only hours or days. Others persist for weeks or months. In a smaller number of people, the symptoms remain constant for years or even decades.
One Critical Distinction: You Know It’s Not Real
The most important feature of depersonalization and derealization is that you always retain awareness that something is off. You know the feeling isn’t accurate. You know you are real and the world is real, even though it doesn’t feel that way. Clinicians call this “intact reality testing,” and it’s what separates DPDR from psychotic disorders like schizophrenia, where that self-awareness is lost.
This awareness is actually what makes the experience so distressing. You’re fully conscious that your perception is wrong, but you can’t shake it. That gap between what you know and what you feel can create intense anxiety, which in turn can make the dissociation worse.
Common Triggers and Causes
Depersonalization rarely appears out of nowhere. The most common triggers include:
- Severe anxiety or panic attacks. Many people first experience depersonalization during or immediately after a panic attack. The brain’s stress response can temporarily alter how you process sensory information, creating that detached feeling.
- Trauma. Childhood abuse, neglect, witnessing violence, or any overwhelming emotional experience can trigger dissociative symptoms. Depersonalization is, at its core, a protective mechanism: the brain creates distance from an experience it can’t process in the moment.
- Sleep deprivation. Prolonged lack of sleep disrupts the brain’s ability to integrate sensory input, which can produce feelings of unreality even in people with no psychiatric history.
- Cannabis use. Marijuana is one of the most well-documented substance triggers. Risk factors include adolescent age, high-potency products, a personal or family history of anxiety, and concurrent stress. While most cases are linked to repeated use, even a single use in a first-time user can induce protracted depersonalization-derealization symptoms.
- Other substances. Hallucinogens, ketamine, and certain stimulants can also trigger episodes. In some cases, symptoms persist long after the substance has left the body.
Depression can both cause and result from depersonalization. The emotional numbness that comes with depression overlaps significantly with the detachment of DPDR, and living with chronic dissociation often leads to depression on its own.
When It Becomes a Disorder
Fleeting moments of feeling unreal happen to many people, particularly during periods of stress, fatigue, or illness. These brief episodes are normal and don’t require treatment.
DPDR is diagnosed as a disorder when the episodes are persistent or keep coming back, when you retain awareness that your perceptions aren’t accurate, and when the symptoms cause significant distress or interfere with your ability to work, maintain relationships, or function day to day. A diagnosis also requires ruling out other explanations, including seizure disorders, ongoing substance use, panic disorder, major depression, or other dissociative conditions.
Grounding Techniques That Help During Episodes
Because depersonalization involves a disconnection from your body and surroundings, the most effective in-the-moment strategy is to force sensory reconnection. These are called grounding techniques, and they work by pulling your attention back to concrete, physical reality.
Touch something with a distinct texture: hold an ice cube, press your bare feet into the floor, run your hands under cold water. Listen actively to specific sounds around you, picking them out one by one. Engage your senses deliberately rather than passively. The goal isn’t to make the feeling disappear instantly but to create small anchors to the present moment that weaken the dissociative state over minutes.
A widely used version is the 5-4-3-2-1 technique: identify five things you can see, four you can touch, three you can hear, two you can smell, and one you can taste. It works because it forces your brain to process real sensory data instead of looping on the feeling of unreality.
Treatment for Ongoing Symptoms
No medication has been proven to effectively treat depersonalization-derealization disorder directly. However, medications are sometimes prescribed to address the anxiety or depression that frequently accompany it, which can reduce the intensity and frequency of dissociative episodes indirectly.
The primary treatment is psychotherapy. Cognitive behavioral therapy helps you identify the thought patterns that reinforce dissociation. For example, many people with DPDR develop a habit of constantly monitoring their own perception (“Do I feel real right now?”), which paradoxically keeps the symptoms going. Therapy works on interrupting that cycle. It also addresses the underlying anxiety, trauma, or emotional patterns that triggered the dissociation in the first place.
Recovery timelines vary widely. Some people see improvement within weeks of starting therapy, particularly if a clear trigger like a panic attack or substance use initiated the symptoms. Others with trauma-rooted DPDR may need longer, more sustained treatment. The episodic nature of the condition means symptoms often improve gradually, with episodes becoming shorter, less intense, and less frequent over time rather than stopping all at once.
