Derealization: the part of panic nobody talks about.
The world goes flat, your own voice sounds far away, and you're sure you're losing your mind. You're not, and the standard grounding advice can make it worse.
The short answer
Derealization, the sense that the world has gone flat or unreal, is a common, temporary symptom of panic and intense anxiety, with studies finding between a quarter and three-quarters of people experience it at least once. It is not psychosis; grounding that anchors to identity, time, and place works better than sensory 5-4-3-2-1 exercises, which can pull attention deeper into the distorted signal.
The version of panic that drifts
There's a version of panic that doesn't race. It drifts.
The world goes flat, like a photograph of itself. Your own voice sounds piped in from another room. Your hands look like someone else's hands. You're standing in your kitchen (you know it's your kitchen), but the knowing feels theoretical, a fact about a place rather than the place itself. And beneath all of it runs the most frightening thought in mental life: this is it, I'm losing my mind, and this time it's permanent.
This experience has a name. Two, actually. Derealization is when the world feels unreal; depersonalization is when you feel unreal to yourself. They travel together, and they are a documented symptom of panic and intense anxiety. This is the sentence that matters most: they are common, temporary, and not what your mind is telling you they are.
More common than almost anyone admits
Because people who experience derealization are terrified of what it might mean, they tend not to mention it. To anyone. Which produces a cruel loop: one of the most common anxiety experiences feels, to each person having it, like a private catastrophe no one else has had.
The numbers say otherwise. Emma Hunter and colleagues at the Institute of Psychiatry in London reviewed the epidemiology in 2004 and found that transient depersonalization or derealization (brief episodes, exactly the kind that ride along with panic) is one of the most commonly reported psychiatric-adjacent experiences there is, with studies finding somewhere between a quarter and three-quarters of people encountering it at least once in their lives. It's listed among the standard diagnostic symptoms of a panic attack, right alongside the racing heart. Sleep deprivation, intense stress, and hyperventilation can each produce it in people with no disorder at all.
The mechanism, as best researchers understand it, is protective. When the threat system fires hard enough, the brain can respond by turning the volume down on everything: a kind of emotional circuit breaker that dampens sensory and emotional intensity. The flatness isn't your mind failing. It's your mind shielding, clumsily.
The trapdoor in the usual advice
Here's the subtle problem: the standard grounding advice can make this state worse.
The technique everyone learns (5-4-3-2-1, name five things you can see, four you can touch) was designed to interrupt spiraling thoughts by redirecting attention to the senses. For racing panic it can work. But derealization is a sensory problem. The senses are the thing that has gone strange. Asking someone mid-derealization to attend closely to how unreal everything looks and feels can pull them deeper into the wrongness rather than out of it: inward, toward the very signal that is distorted.
What the dissociation-informed clinical literature (DBT grounding protocols, trauma-informed CBT) suggests instead is anchoring outward: not to raw sensation, but to identity, time, and place. The facts of you. Your name. Today's date. Where you are, specifically. One thing within reach that you can touch, one thing nearby with history in it: the mug you always use, the jacket that's been on that chair all week. Not "notice five things" but "re-thread yourself to the world," one verifiable fact at a time.
And crucially: no inquest. The question why do I feel like this keeps the alarm system engaged. The answers come later, when you're back. They always come easier when you're back.
Different states need different doors
The larger lesson here goes beyond derealization. "Panic" is not one experience. A racing heart, a drifting sense of unreality, and a spiral of catastrophic thought are three different states, and the intervention that fits one can fail, or backfire, for another. The breath is the front door for racing panic. The reality anchor is the door for drifting. Sensory engagement is the door for spiraling thought. Handing everyone the same technique is like handing everyone the same key.
How Stillee routes it
This is why Stillee's panic flow begins, briefly, with a choice of three icons: racing, drifting, spiraling. Tap "drifting" and you are not sent to a breathing circle. You're taken through a five-step reality anchor built on the clinical grounding literature: your name, today's date, where you are, one thing you can touch, one familiar thing nearest you. It closes on a single word: anchored.
If choosing is beyond you in the moment (it often is), a four-second ring makes the choice for you. And the flow never asks you to analyze the unreality, rate it, or explain it. The inquest can wait.
Most tools treat "drifting" and "racing" as the same emergency. They're not, and the difference is exactly the part of panic nobody talks about: the part where you quietly conclude you've lost your mind. You haven't. Millions of people have stood in that flattened kitchen. The world comes back. We built the flow that waits with you until it does.
The panic flow, reality anchor included, is free. Forever.
