The short answer: Yes. Feeling that the world is unreal is a recognized panic attack symptom. A 1989 study of 150 people with panic disorder found it in 34.7% of them, per Cassano and colleagues. Most episodes fade as the anxiety settles. When it persists for months on its own, it may be a separate condition.

What does derealization from anxiety feel like?

Derealization is a sense that your surroundings are not quite real. People often say the room looks flat, far away, foggy, or staged. Sounds can seem muffled. Familiar places can look strange for a moment.

Depersonalization is the inward version. You feel cut off from your own body, thoughts, or feelings, as if you are watching yourself. The two often happen together, so clinicians group them as depersonalization/derealization.

The key feature is that you know it is a feeling. The Merck Manual Professional Edition (reviewed June 2025) calls this "intact reality testing." You notice the world feels unreal, and that awareness is what frightens you. This is different from psychosis, where a person believes something false is actually true.

MedlinePlus lists "feelings of unreality" and "feelings of detachment" among the symptoms of a panic attack. They sit on the same list as a racing heart, sweating, and chest pain. If you have other odd sensations, our list of weird anxiety symptoms covers more of them.

How common is derealization during panic attacks?

Brief episodes are common. The Merck Manual states that between 25% and 75% of people have at least one passing experience of depersonalization or derealization in their lives. The full disorder is much rarer, at about 1% to 2%.

Studies of people with panic disorder give these figures:

  • Cassano and colleagues, 1989: 34.7% of 150 patients with panic disorder had derealization or depersonalization during attacks. That group had earlier onset and more avoidance.
  • Seguí and colleagues, 2000: 24.1% of 274 patients with panic disorder had depersonalization during attacks. Their panic disorder was more severe, with more attacks.
  • Michal and colleagues, 2011: In a survey of 2,512 German adults, 3.4% scored at a clinically significant level of depersonalization. It was strongly linked with depression and anxiety.
  • Simeon and Stein, 2025: In the US National Comorbidity Survey Replication, past-month clinically significant depersonalization/derealization affected 0.9% of adults. It was most common in people with both mood and anxiety disorders (11.8%).

So the symptom is common in panic attacks, but it tends to mark heavier anxiety, not a new danger.

Is it a passing episode or depersonalization-derealization disorder?

Most anxiety-driven derealization rises with a panic attack and fades as the body calms. That is a symptom of the panic, not a separate diagnosis. The difference between panic and anxiety attacks explains why panic tends to bring the strongest sensations.

Under DSM-5-TR criteria, as summarized by the Merck Manual, depersonalization/derealization disorder needs all of these:

  • Persistent or recurrent episodes of depersonalization, derealization, or both.
  • Intact reality testing during the episodes.
  • Significant distress or trouble functioning at work, at home, or socially.
  • No better explanation from another condition, such as panic disorder, depression, seizures, or substance use.

That last point matters. If the unreal feeling only shows up during panic attacks, the diagnosis is usually panic disorder. The Merck Manual notes the separate disorder usually starts in the teens, with a mean onset age of 16. Only about 5% of cases start after age 25. It often waxes and wanes, but in some people it stays constant for years.

What can you do during an episode?

Fighting the feeling or checking it over and over tends to feed it. In a 2005 open study of cognitive behavioral therapy, the treatment focused on reading the symptoms as harmless and cutting back on avoidance and symptom monitoring. The Merck Manual describes grounding with the five senses, such as loud music or holding ice.

A short sequence built from those approaches:

  1. Name it. Say to yourself, "This is derealization. It is anxiety, and it passes." Labeling it lowers the fear of going crazy.
  2. Use a strong sense. Hold an ice cube, splash cold water on your face, or smell something sharp, like peppermint or coffee.
  3. Anchor your eyes. Pick five objects and describe each one aloud: color, edge, texture.
  4. Slow your breath. Breathe out longer than you breathe in. Try a count of 4 in and 6 out.
  5. Return to a task. Do something simple with your hands. Stop checking whether the feeling is still there.
  6. Note the trigger later. Write down sleep, caffeine, alcohol, cannabis, or stress from that day.

Expect the feeling to fade over minutes, not seconds. The goal is to stop adding fear to it, not to force it away.

What else can make the world feel unreal?

Anxiety is the most common cause, but not the only one. The Merck Manual lists seizures, substance use, depression, and other dissociative disorders as conditions that can produce the same feeling.

  • Drugs. In a 2009 survey of 394 adults with chronic depersonalization, about half said a drug first set it off. Cannabis and hallucinogens were the most common triggers, followed by ecstasy.
  • Seizures. Unreality can occur during or after a seizure. Warning signs include lost time, staring spells, odd smells, or confusion afterward.
  • Trauma. Detachment is common after trauma. If it began after a frightening event, ptsd.md covers dissociation and PTSD care.
  • Depression and poor sleep. Simeon and Stein found the strongest link when depression and anxiety occur together.

Doctors may order an EEG or MRI when symptoms are atypical, per the Merck Manual. See when to see a doctor for anxiety for other red flags.

How is persistent derealization treated?

When derealization comes with panic attacks, treating the panic usually treats the derealization. MedlinePlus lists cognitive behavioral therapy and SSRIs or SNRIs as standard care for panic disorder.

For the separate disorder, therapy is the main tool. In the Hunter 2005 study, 21 patients received CBT. They improved on measures of unreality, anxiety, depression, and daily function, and 29% no longer met criteria at the end. The study was small and had no control group.

Medicine has weaker support. The Merck Manual states no drug has clearly shown it works for the disorder itself. SSRIs or lamotrigine may help some people, likely by treating the anxiety or depression that comes with it.

The bottom line

Anxiety can make the world feel unreal, and it happens to many people during panic attacks. You stay aware that it is a feeling, which separates it from psychosis. Grounding and less symptom checking help it pass. If it lasts for weeks, began after drug use, or comes with lost time, see a doctor.
