What Is Dissociation? What It Feels Like, Why It Happens and How to Come Back

Dissociation is a disconnection between your thoughts, memories, feelings, actions or sense of who you are. In its everyday form — daydreaming, or zoning out on a familiar drive — the American Psychiatric Association, quoting the Sidran Institute, describes it as a normal process. Under overwhelming stress, it can be the mind's way of getting through. It becomes a concern when it keeps cutting you off from the present, leaves gaps in your memory, or gets in the way of your life.

If you've been feeling far away from your own life, or as if the room around you isn't quite real, this is written for you.

What Is Dissociation?

The American Psychiatric Association (APA), which publishes the DSM-5-TR diagnostic manual, says dissociative disorders involve problems with memory, identity, emotion, perception, behaviour and sense of self. The World Health Organization's ICD-11 describes an involuntary break in how identity, sensations, perceptions, emotions, thoughts, memories, control over bodily movements and behaviour normally fit together (ICD-11, dissociative disorders, 6B60–6B6Z).

In both, the APA notes, the person stays aware of reality and knows the experience is unusual. ICD-11 groups that disorder with dissociative amnesia and dissociative identity disorder (DID).

What Does Dissociation Feel Like?

The NHS page on dissociative disorders describes experiences such as:

• →A world that seems foggy or lifeless, and feeling disconnected from yourself and from what's around you.
• →Numbness, including feeling little or no physical pain.
• →Lost time. Forgetting time periods, events or personal information. In dissociative amnesia, the NHS describes gaps much more severe than normal forgetfulness, and finding yourself somewhere strange without knowing how you got there.
• →Uncertainty about who you are.

From the outside you may look calm, even flat, and the people around you may have no idea.

You may also be carrying a worry you haven't said out loud: am I losing my mind? The Merck Manual notes that people with depersonalization or derealization can carry that exact fear, while staying aware that the detachment is how things feel, not how things are. If you're seeing or hearing things other people don't, or you can't tell what's real, contact a doctor promptly.

Is Dissociation Bad, or Is It Normal? From Zoning Out to Dissociative Disorders

Dissociation covers a range, from everyday to clinical:

• →Everyday absorption. The APA, quoting the Sidran Institute, gives daydreaming, highway hypnosis and getting lost in a book or movie as examples.
• →Brief detachment under strain. The Merck Manual says about half of people have felt detached from themselves or their surroundings at one time or another, and that episodes can follow life-threatening danger, certain drugs, or going without sleep.
• →Dissociation during or after trauma. According to the APA, acute stress disorder and post-traumatic stress disorder (PTSD) may involve dissociative symptoms such as memory loss, depersonalization or derealization.
• →Dissociative disorders. Diagnoses such as depersonalization-derealization disorder, dissociative amnesia and DID, which need a clinician's assessment. Merck puts depersonalization-derealization disorder at one to two people in every hundred.

This isn't a ladder. Where your experience fits is a question for a professional, not a checklist.

Why Does Dissociation Happen?

The explanation clinical sources give is protection. The APA, quoting the Sidran Institute, says dissociation can help a person tolerate what might otherwise be too difficult to bear, by mentally escaping the fear and pain of an accident, disaster or crime — which can make details harder to remember afterwards. The NHS calls it a normal defence mechanism during a traumatic time.

It becomes a problem, the NHS says, when the environment is no longer traumatic but the person still lives as if it is. The switch-off that once helped can arrive in an argument or a crowded store, long after the danger has passed. The window of tolerance and functional freeze articles describe this shutdown: dropping below the zone where you can think and feel at once, and seeming fine outwardly while feeling far away inside.

The trauma explanation isn't settled. In a 2014 commentary in Psychological Bulletin on a meta-analysis published there two years earlier, Lynn and colleagues reviewed the eight predictions that meta-analysis set out and found them largely wanting in empirical support. They argued it moved too quickly from correlational data to causal conclusions, and accept trauma may play a causal role while holding it is less central and specific than the trauma model claims. That meta-analysis, by Dalenberg and colleagues (2012), had concluded the evidence supported trauma as a cause. So dissociating doesn't by itself mean something happened that you've forgotten, or that you should go hunting for hidden memories.

How Do You Stop Dissociating?

There's no switch that turns dissociation off on demand. Grounding aims for something smaller: bringing your attention back to the present through your senses. It's a coping tool for the moment, not treatment.

Worth knowing first: the Cleveland Clinic notes that focusing on symptoms, going over them repeatedly, or trying to control them can increase anxiety and worry, which in turn may make symptoms worse. Use these in the moment, then put them down; if you find yourself checking over and over whether the feeling has lifted, raise that with a doctor.

The Merck Manual describes grounding as using the five senses to feel more connected to yourself and the world. eMentalHealth.ca, written by mental health professionals at CHEO in Ottawa, sets out a 5-4-3-2-1 exercise, and wording a loved one can use to orient someone who has lost track of the day. Ideas at that level:

• →Count down through your senses. Name five things you can see, four you can touch, three you can hear and two you can smell, then one thing you're grateful for.
• →Use temperature. Hold something cool in your hand. Cold water changes heart rate quickly, so skip the water, stay with something cool to hold, and check with your healthcare provider if you have a heart condition, an irregular or very slow heartbeat, low blood pressure or an eating disorder, are pregnant, or take medication that affects heart rate.
• →Describe the moment, not yourself. Merck lists naming what's happening as you go among its techniques. Out loud or in your head: everything looks far away right now, it's Tuesday, and I'm standing in my kitchen.
• →Move a little. Stand up, press your feet into the floor, or look slowly around the room. The window of tolerance article explains why a small, safe upshift can suit shutdown better than slow breathing.

Limits: a 2025 paper in Trauma, Violence, & Abuse notes that grounding techniques haven't been through efficacy studies, for lack of an agreed, measurable definition of grounding (Hammond and Brown, 2025). If one makes you feel worse, stop.

If the unreality started or got stronger during meditation or presence practice, stop rather than push through and talk to your doctor; the guide to The Power of Now covers this. Tell your doctor too if alcohol or other drugs are part of the picture.

Grounding is for getting through a moment. It isn't an answer to losing time, to gaps in memory for things you did, or to detachment that keeps coming back. Those belong with a doctor.

When Should You Get Assessed for Dissociation?

Talk to your family doctor or nurse practitioner if you're losing time, finding yourself somewhere without knowing how you got there, noticing gaps in memory, feeling unsure who you are, or finding that detachment is getting in the way of daily life. The NHS notes a doctor may examine you and run tests to check for another illness, and ICD-11 expects medication and substance effects, sleep-wake disorders and neurological conditions to be ruled out.

Some symptoms need a faster route. The NHS lists seizures among the symptoms of dissociative disorders. A first or unexplained seizure or fainting episode, new numbness or loss of sensation, weakness, or a change in speech or vision is a reason to be seen the same day: go to an emergency department, or call 911 if someone is unresponsive, injured or still seizing.

If you're hurting yourself, or you've thought about it, call or text 9-8-8 (Canada, 24/7), and tell your doctor. If you're in immediate danger, call 911.

Dissociative disorders, including DID, need specialized assessment and care. The International Society for the Study of Trauma and Dissociation (ISSTD) advises finding a therapist with specific training and expertise in treating them, and its fact sheet on getting treatment suggests asking whether they've treated the condition you're being assessed for, what training they have, and whether they get supervision. Your doctor can help with a referral, and the NHS notes there's no specific medicine for dissociation.

How Does Trauma Therapy Work With Dissociation?

At a pace you can manage. ISSTD's fact sheet describes treatment that first helps you stay safe and manage your feelings, then works through traumatic memories when you're ready; telling the whole story isn't the first step. In EMDR (eye movement desensitization and reprocessing, a structured trauma therapy), history and preparation come before any memory is processed, and when staying present is hard, TEO's approach is to build steadiness first. Because TEO works only by video, which offers less containment than a room, dissociating easily can be a reason to work on it in preparation or to consider in-person care instead. That page sets out where the method fits, where it waits, and what to weigh about working by video rather than in a room; the trauma therapy page sets out the pacing.

Can TEO Counselling Help With Dissociation?

What TEO doesn't offer: DID or dissociative-disorder specialty care, diagnosis, or medication. You can raise dissociation in the free 15-minute consultation and ask whether it's something TEO works with. Assessment for a dissociative disorder starts with your doctor.

Where it can fit: dissociation that's part of trauma or PTSD, worked on at a pace where stabilization comes before memory processing. Sessions are online for clients in British Columbia, Ontario, Alberta, Saskatchewan, Manitoba, and Newfoundland and Labrador.

• →Mohamad Shabib, MACP, CCC, Registered Psychotherapist (Qualifying) with the CRPO (Ontario), works with clients in all six provinces, in English or Arabic. His training includes Advanced EMDR training through an EMDRIA-approved programme, CBT for Trauma (cognitive behavioural therapy adapted for trauma, Levels 1 and 2) and DBT-informed work (dialectical behaviour therapy, skills for intense emotion) in individual sessions, not a skills group.
• →Alison Shaji, MA, RCC #22608 (BCACC), works with clients in British Columbia only, in English, Hindi or Malayalam, and is trained in EMDR, CBT and DBT-informed work.

Individual sessions are $150 per 60 minutes (see fees); what private therapy costs elsewhere in Canada, and the free and lower-cost routes, are in our guide to what therapy costs in Canada. The first step is a free 15-minute consultation by video or a scheduled phone call, booked online, with no referral needed. Counselling isn't a crisis service: in a crisis, call or text 9-8-8 (Canada, 24/7).

A Small Next Step

One thing to do today: write down what you'd want a doctor or a therapist to know — when you last felt far away, and what helped you come back. Keep it short, and stop if it makes you feel worse. Then bring it to your doctor, or to a free consultation. You can also text (519) 760-5211 with a question first.
