What Is Dissociation? Understanding Why You Feel Disconnected from Yourself
Have you ever been driving on a familiar route, only to suddenly arrive at your destination with absolutely no memory of the journey? For a brief period, your brain went on autopilot while your conscious mind drifted elsewhere.
This is a mild, everyday example of dissociation. It is a perfectly normal function of the human brain. But what happens when that feeling of disconnection doesn't just happen on a boring commute? What if you frequently feel completely detached from your body, as if you are watching your life happen from the outside? What if you regularly lose chunks of time, or feel like the world around you is slightly fake, like a movie set?
If you are experiencing this, you might feel frightened or think you are "going crazy." You are not. You are experiencing dissociation, a brilliant and highly effective biological survival mechanism that your brain developed to protect you from overwhelming pain.
If you have a history of trauma or Complex PTSD (CPTSD), PTSD with dissociative features or a dissociative disorder, understanding dissociation is often the missing puzzle piece in your healing journey.
What is Dissociation?
At its core, dissociation is a disconnection. It is a biological protection mechanism that separates your conscious awareness from threatening or overwhelming experiences [1].
When an animal is caught by a predator and cannot fight or flee, its nervous system will initiate a "freeze" response. The animal collapses, goes numb, and its brain releases pain-killing endorphins. This is a survival strategy: playing dead might make the predator lose interest, and the numbing ensures that if the animal is killed, it won't feel the full agony of it.
Humans have this exact same biological mechanism. When a child experiences profound or ongoing trauma—such as abuse, neglect, or living in a highly volatile environment—they usually cannot fight back or run away. They are trapped. To survive the inescapable terror, their brains initiate the freeze response. They "tune out" or dissociate from the threatening experience [2].
As Dr. Arielle Schwartz notes in The Complex PTSD Workbook, dissociation allows a child to separate the part of themselves that has to keep up with the daily tasks of living (going to school, eating dinner) from the part of themselves that holds the terror, shame, and pain of the trauma.
The Spectrum of Dissociation
Dissociation exists on a continuum. It ranges from mild, everyday spacing out to severe, chronic disconnection. Trauma survivors often bounce around this spectrum depending on their stress levels and triggers.
1. Mild Dissociation (Spacing Out and Numbing)
At the lower end of the spectrum, dissociation looks like brain fog, sleepiness, or having a hard time concentrating. You might find it incredibly difficult to talk about certain experiences, your mind simply going blank when you try. Many people use external tools to facilitate this numbing, such as scrolling mindlessly on a phone for hours, binge-watching television, or emotional eating.
2. Depersonalisation
Depersonalisation is the profound sensation of being disconnected from your own body, thoughts, or feelings. People experiencing depersonalisation often describe it as:
- Feeling like a robot or a zombie.
- Looking in the mirror and not recognising the person looking back.
- Feeling like you are floating above your body, watching yourself go through the motions of your day.
- Feeling a physical numbness, as if your body is wrapped in cotton wool or you are underwater.
3. Derealisation
While depersonalisation is a disconnection from the self, derealisation is a disconnection from the environment. If you are experiencing derealisation, the world around you might feel:
- Surreal, fake, or like a dream.
- Distorted in size or shape (things might look too big, too small, or two-dimensional).
- Visually altered, as if you are looking at the world through a dirty pane of glass or a fishbowl.
- Emotionally flat, where loved ones or familiar places suddenly feel completely alien to you.
4. Severe Dissociation and "Lost Time"
At the most extreme end of the spectrum, dissociation can cause amnesia. You might have entirely repressed memories of your childhood trauma. In your day-to-day life, you might experience "lost time"—suddenly "waking up" in the middle of the day with no memory of how you got there or what you have been doing for the past several hours.
Why Dissociation Becomes a Problem
In childhood, dissociation saved you. It allowed you to survive the unsurvivable by putting the pain in a mental lockbox. You should thank your brain for being so clever and protective.
The problem arises in adulthood. The brain is an efficient learning machine; if dissociation worked to protect you from extreme danger in the past, your brain will start using it to protect you from any perceived threat in the present.
If you have CPTSD, your nervous system is highly sensitised. When you experience a minor conflict with a partner, receive a critical email at work, or even just feel a surge of a vulnerable emotion like sadness or joy, your brain might interpret that as a massive threat. Before you even realise what is happening, the trapdoor opens, the freeze response kicks in, and you dissociate.
You might want to stay present and connect with your partner, but you suddenly feel completely numb and blank. You might want to feel the joy of a special occasion, but you feel like you are watching it happen to someone else. Dissociation kept you alive in the past, but it is keeping you from actually living in the present.
Healing: Thawing the Freeze Response
Healing from dissociation is not about aggressively forcing yourself to stay present or punishing yourself for zoning out. Forcing a dissociated nervous system to confront trauma before it is ready will only cause it to dissociate harder.
Healing requires gentleness, pacing, and a deep respect for your body's survival mechanisms. The goal is to slowly expand your "window of tolerance"—the zone where your nervous system feels safe enough to experience emotions without needing to shut down [3].
Here is how that process generally unfolds in trauma therapy:
1. Removing the Shame
The first step is recognising that your dissociation is not a flaw; it is a brilliant protection mechanism. When you notice yourself checking out, try replacing self-criticism (*"Why am I so broken?"*) with curiosity and compassion (*"My brain thinks I am in danger right now. It is trying to protect me."*).
2. Grounding and Somatic Awareness
Because dissociation pulls you out of your body, healing requires slowly and safely bringing you back into it. This is done through somatic (body-based) grounding techniques. This might involve focusing on the physical sensation of your feet pressing into the floor, holding a piece of ice, or naming five things you can see in the room. We start very small, teaching the nervous system that the present moment is safe.
3. Parts Work (Internal Family Systems)
Many trauma therapists use "parts work" or Ego State therapy to treat dissociation. This involves recognising that the part of you that dissociates is like a dedicated security guard. In therapy, we gently communicate with this protective part, thanking it for keeping you alive, and slowly showing it that the trauma is over and it doesn't need to work so hard anymore.
4. Processing the Trauma
Only when you have strong grounding skills and a wider window of tolerance do we begin to process the underlying trauma. Therapies like EMDR (Eye Movement Desensitisation and Reprocessing) are highly effective, as they allow you to process the frozen traumatic memories while remaining safely anchored in the present moment.
Dissociation and Relationships
One of the most painful aspects of living with chronic dissociation is the impact it has on your relationships. Intimacy requires presence. When you are in a close relationship with someone you love and you suddenly feel yourself "check out" — going blank, feeling numb, or watching the conversation from somewhere outside yourself — it is deeply distressing for both people involved.
Your partner may feel like they are talking to a wall, or that you simply don't care. You may feel terrified of their confusion or frustration, which can push you further into dissociation. Over time, this pattern can create a painful cycle of disconnection that erodes even the most loving relationships.
It is important to understand that this is not a choice. You are not choosing to check out of your relationship. Your nervous system is activating an automatic survival response because intimacy and vulnerability feel, on some deep biological level, like a threat. This is because for many trauma survivors, the people who were supposed to be the safest — parents, caregivers, partners — were the source of the original harm.
Healing this pattern involves two things: building your capacity to stay present in your body (through grounding and somatic work), and slowly, carefully rebuilding a felt sense of safety in close relationships. This is often one of the most profound and meaningful parts of the healing journey.
Recognising Your Own Dissociation
One of the tricky things about dissociation is that, by its very nature, it can be hard to notice when it is happening. You are, after all, disconnected from your own awareness. Here are some signs that you may be dissociating more than you realise:
You frequently "come to" mid-conversation, having missed what the other person just said. You find yourself staring at a screen for hours without any memory of what you watched. You feel emotionally flat or numb in situations where you know you "should" feel something. You feel like you are on autopilot, going through the motions of your day without any real sense of being present in it. You have been told by people close to you that you "zone out" or seem to be "somewhere else." You find it difficult to recall significant periods of your life, particularly childhood.
If several of these resonate with you, it is worth exploring with a trauma-informed therapist. Dissociation exists on a spectrum, and even mild, chronic dissociation can significantly impact your quality of life, your relationships, and your sense of self.
The Role of Shame in Dissociation
Shame and dissociation are deeply intertwined. For many trauma survivors, the original trauma involved experiences that were profoundly shameful — abuse, neglect, or violations of bodily autonomy. The shame attached to these experiences is so overwhelming that the mind cannot hold it consciously. Dissociation becomes the mechanism by which the shame is kept out of awareness.
But shame has a way of leaking through. Even when the specific memory is dissociated, the emotional residue of shame can colour every aspect of your life. It might show up as a pervasive sense of being fundamentally bad, broken, or unworthy. It might show up as an inability to receive care or compliments. It might show up as self-sabotage, just when things are going well.
Healing from shame-based dissociation requires what Dr. Kristin Neff calls "self-compassion" — the ability to turn toward your own pain with the same warmth and understanding you would offer a dear friend. This is not a quick fix, and it often requires the support of a skilled therapist. But it is possible. The shame that was placed on you by others does not belong to you, and you do not have to carry it forever.
A Note on Dissociation and Safety
If your dissociation is severe — if you are regularly losing significant periods of time, finding yourself in places with no memory of how you got there, or experiencing what feels like different "parts" of yourself taking over — it is important to seek professional support as soon as possible. Severe dissociation can be a sign of a dissociative disorder such as Dissociative Identity Disorder (DID), which requires specialist trauma-informed care.
