Everything looks slightly off. The world has a quality of unreality to it, like you are watching your life from behind glass, or inside a dream that keeps going even though you know you are awake. Colors may look different. Your surroundings may feel unfamiliar even when they are not. Other people may seem somehow less real than they should.
This is derealization, and if you are reading this because you are experiencing it or recently experienced it, the most important thing to know first is this: it is not dangerous, it will pass, and the experience of the world feeling unreal is the experience of a nervous system that has gone into a protective mode, not evidence that you have lost your mind.
Grounding techniques for derealization are practical, in-the-moment approaches that help bring the nervous system back from the dissociative state. This post explains what derealization is, why it happens, which grounding techniques work and why, and when the experience warrants clinical support.
What is Derealization?

Derealization is a dissociative experience in which the external world feels unreal, dreamlike, foggy, or distant. It is one of two primary forms of dissociation: the other, depersonalization, involves a similar sense of unreality about the self rather than the environment. They frequently occur together, which is why the diagnostic term is often depersonalization-derealization disorder when the experiences are persistent and impairing.
NIMH documents dissociative experiences as occurring on a spectrum from mild, transient states that most people experience at some point (the sense of unreality during extreme fatigue, when waking from a dream, or after intense stress) to chronic, impairing dissociation that requires clinical treatment. The APA’s clinical definition of dissociative disorders describes this same spectrum, from momentary disconnection to significant disruption in memory, identity, and perception.
Common descriptions include:
- Feeling like you are watching yourself from outside your body
- The environment looking two-dimensional or flat, like a set or a screen
- Colors appearing washed out or more vivid than normal
- Familiar places feeling unfamiliar or strange
- Other people seeming mechanical, robot-like, or less human
- Time distortions: time moving too slowly, too quickly, or feeling suspended
- A sense that you have been here before but it does not feel real (distinct from déjà vu)
- The feeling of being behind glass or a veil between yourself and the world
The experience is often accompanied by anxiety, which can both precipitate and prolong it. The anxiety about the derealization, the fear that it means something is seriously wrong, often makes the episode worse.
Why Derealization Happens
Derealization is a dissociative response: the nervous system’s way of managing an overwhelming experience by reducing the intensity of sensory input and emotional engagement with the environment. The International Society for the Study of Trauma and Dissociation frames dissociation on a spectrum: at the mild end, daydreaming and absorption; at the more extreme end, derealization, depersonalization, and, in cases of severe trauma, amnesia and identity fragmentation. Derealization sits in the middle of this spectrum.
Common triggers:
Anxiety and panic. Derealization is a very common feature of panic attacks and heightened anxiety states. The hyperventilation that often accompanies panic reduces carbon dioxide levels in the blood, which can produce the dreamlike, disconnected quality of derealization. The anxiety activates the dissociative response as a protective mechanism.
Chronic stress and exhaustion. The nervous system that has been under sustained stress for a long time may begin to dissociate in response to even mild triggers. The derealization is a signal that the system is overtaxed.
Sleep deprivation. Significant sleep deprivation reliably produces mild dissociative experiences. The world begins to have a dreamlike quality when the boundary between sleep and waking is depleted.
Substance use. Cannabis, alcohol, and other substances can precipitate derealization episodes, and cannabis in particular is associated with derealization, especially in people who are already anxiety-prone.
Trauma history. People with trauma histories, particularly histories involving chronic or developmental trauma, are more likely to experience derealization as a dissociative response. The nervous system learned dissociation as a protective strategy in the context of overwhelming early experience.
Grounding Techniques for Derealization: What Works and Why
Grounding techniques for derealization work by engaging the sensory systems that the dissociation has dampened, bringing the nervous system back into contact with present physical reality and reducing the gap between the experience and the world.
The most effective grounding techniques for derealization work at the sensory level rather than the cognitive level. Telling yourself “this is not real, I need to calm down” does not work because the dissociation is not a thought to be corrected. It is a nervous system state to be changed through sensory and physiological input.
Sensory grounding
5-4-3-2-1 technique. Name five things you can see, four things you can touch, three things you can hear, two things you can smell, one thing you can taste. The deliberate, slow inventory of sensory experience redirects attention to the present physical environment and anchors awareness in immediate reality. This is one of the most widely recommended grounding techniques for derealization and one of the most evidence-supported for breaking the dissociative state.
Intense sensory input. Temperature extremes in particular are effective: hold ice cubes, splash cold water on your face, run your hands under cold water. The strong sensory input provides the nervous system with unambiguous information about the physical environment, which is harder to dissociate from than neutral sensory experience.
Textured surfaces. Running your hands over rough or textured surfaces, feeling the distinct quality of different textures, provides the kind of specific, differentiated sensory input that pulls attention back into the body and the physical environment.
Taste. Strong flavors, particularly sour or spicy, are effective grounding agents. The intensity of the taste sensation is difficult to experience dissociatively.
Physical and movement-based grounding
Deliberate movement. Intentional, slow physical movement, particularly movement that involves proprioception (awareness of the body’s position in space) such as pressing the feet firmly into the floor, standing and feeling the weight of the body, or slow walking with attention to each step, activates the body awareness systems that derealization dampens. Approaches like somatic exercises build this kind of body awareness more broadly, beyond the acute moment of an episode.
Rhythmic bilateral stimulation. Slow, rhythmic bilateral stimulation, tapping alternating sides of the body, crossing arms over the chest and tapping alternating shoulders, or slow walking, activates both brain hemispheres and has been associated with reduction in dissociative states. This is related to the mechanism used in EMDR therapy for trauma processing.
Breathing to reduce hyperventilation. If anxiety and hyperventilation are contributing to the derealization, slowing the breath and specifically extending the exhale reduces the carbon dioxide deficit that can exacerbate dissociative symptoms. Breathe in for 4 counts, out for 6, for several minutes.
Physical contact. The pressure of a hand on a firm surface, sitting on the floor rather than a chair, feeling the firmness of a wall: the proprioceptive input of firm physical contact helps anchor physical experience.
Cognitive anchoring
Naming. Verbally naming what you can see around you, out loud if possible, engages the language system alongside the sensory systems and provides a structured way to make contact with the reality of the environment.
Orientation statements. “I am [name]. I am in [location]. It is [date and time]. I am safe.” These statements are not magic. They work because the act of orienting to specific, concrete factual information engages the cognitive systems that the derealization has partially suspended.
Reminding yourself what derealization is. “This is derealization. It is a known experience. It is not dangerous. It will pass.” The psychoeducational reminder reduces the anxiety about the derealization, which reduces one of the factors that can prolong the episode.
What Does Not Help With Derealization

Some responses to derealization are instinctive but counterproductive.
Checking in on whether it is still happening. Repeatedly asking yourself “do I feel more real now?” focuses attention on the experience of derealization rather than on the external environment, which maintains the dissociative state.
Trying to think your way out of it. Analyzing the experience, worrying about what it means, trying to figure out why it is happening: these cognitive responses engage the internal mental space rather than the external physical reality, which is the opposite of what grounding achieves.
Avoiding triggers. Derealization that produces avoidance of the situations where it occurred is derealization on its way to becoming a phobia. The avoidance maintains the anxiety about derealization and increases its power over time.
Substances. Cannabis in particular is associated with derealization and can significantly worsen it. Alcohol provides temporary relief and often produces or worsens derealization during and after use.
Derealization in New York City
The specific conditions of New York City life create a particular set of derealization triggers worth naming.
Chronic sleep deprivation. New York’s pace and its professional culture produce some of the most sleep-deprived populations in the country. The dreamlike quality of derealization is meaningfully more likely in a consistently sleep-deprived nervous system.
Chronic stress without adequate recovery. The sustained activation of New York’s professional demands keeps the nervous system close to the threshold at which dissociation becomes a protective response. The derealization that appears during a difficult period is often the signal that the stress load has exceeded the nervous system’s current capacity.
Cannabis use in a legal state. New York’s cannabis legalization has made cannabis more accessible and more socially normalized. For anxiety-prone individuals, cannabis is a significant derealization trigger, and its normalization in New York’s social culture means that the connection between cannabis use and dissociative experiences is often not recognized.
Overstimulation. The sensory density of New York City, the noise, the crowds, the visual complexity, can produce a kind of sensory overwhelm that the nervous system manages through mild dissociation. The city is, in a specific way, a derealization-producing environment.
As Kristie Tse, LMHC-D, describes it: “Derealization is one of those symptoms that people are often too embarrassed or frightened to mention in therapy, because they worry it means something more serious than it usually does. Most of the time, it is the nervous system doing what nervous systems do when they are overwhelmed. The grounding techniques help in the moment. The clinical work addresses what the nervous system is responding to.”
When Derealization Warrants Clinical Support
Transient derealization in the context of acute stress or anxiety is common and does not automatically require clinical treatment beyond the self-management strategies described above.
Clinical support is warranted when:
- Derealization is occurring frequently or is nearly constant
- The episodes are significantly impairing daily functioning, work, or relationships
- Derealization is accompanied by significant anxiety, depression, or other symptoms
- The grounding techniques described in this post are not sufficient to manage the episodes
- Derealization began following a traumatic event or period of significant trauma
- The experience is causing significant distress and fear
For derealization related to anxiety, anxiety therapy that addresses the anxiety driving the dissociative response is the appropriate clinical approach. For derealization related to trauma, trauma-informed therapy that addresses the trauma alongside the dissociation is indicated. Somatic approaches are particularly useful for dissociative presentations because they work directly with the body-level disconnection that characterizes derealization.
If you are experiencing severe or persistent dissociation, significant confusion about what is real, or derealization that is accompanied by other significant symptoms, please contact a mental health professional. If you are in crisis, please contact the 988 Suicide and Crisis Lifeline by calling or texting 988.
Frequently Asked Questions About Derealization
Is derealization dangerous? Derealization itself is not medically dangerous. It is a distressing experience but not a medical emergency. The experience of the world feeling unreal does not mean you are losing your mind, and it does not cause any physical harm. That said, persistent or severe derealization warrants clinical evaluation.
Is derealization the same as depersonalization? They are related but distinct. Derealization involves the external world feeling unreal. Depersonalization involves the self feeling unreal: a sense of being detached from your own body, thoughts, or feelings. They frequently co-occur, and the clinical term depersonalization-derealization disorder captures both.
Can derealization be a symptom of something more serious? Derealization occurs in the context of anxiety disorders, depression, PTSD, and dissociative disorders, and can be a feature of some neurological conditions. Derealization that is persistent, severe, or accompanied by other significant symptoms warrants a clinical evaluation to clarify what is driving it and what the appropriate treatment is.
Why does derealization happen during panic attacks? Panic attacks typically involve hyperventilation, which reduces carbon dioxide levels in the blood. This physiological change produces a range of symptoms including tingling, dizziness, and derealization. The derealization during a panic attack is partly physiological and partly the nervous system’s dissociative response to the overwhelming anxiety of the attack.
Will derealization go away on its own? For most people, transient derealization episodes resolve on their own as the triggering anxiety or stress reduces. For people with persistent or frequently recurring derealization, treatment that addresses the underlying anxiety or trauma is typically needed.
