Dissociation is the experience of a rupture or interruption in the continuity of our inner experience. It can show itself as a distancing from feelings, as a sense of numbness or deadness, but also as a deeper sense of estrangement from the self, the body, reality or our relationships.
Dissociation is a spectrum of experiences ranging from everyday, passing forms to more intense and persistent states. Two of its best-known forms are depersonalisation and derealisation.
In depersonalisation, a person experiences themselves as an outside observer of their own thoughts, feelings or bodily sensations. They may feel as though they are watching themselves function without taking part in it and without really feeling what they are living. In derealisation, by contrast, the environment seems dreamlike, distant, empty, lifeless or unreal. Although these experiences can be distressing, the person usually retains the awareness that this is an alteration of their experience and not reality itself.
We all have the capacity to dissociate. When we drive without remembering the route, when we get lost in our thoughts, or when a stressful event distracts us so much that we cannot remember what we heard or what happened around us, we are experiencing mild forms of dissociation. Research shows that transient dissociative experiences are very common in the general population and that most people will experience some form of them at least once in their lives. At this level, dissociation belongs to the normal spectrum of human functioning.
Brief episodes of depersonalisation or derealisation, which may last from a few minutes to hours or even a few days, are not necessarily worrying. They can appear as a passing response to exhaustion, sleep deprivation, intense stress or a period of psychological strain. Someone may feel as though they are living inside a fog, as though they are watching their life from behind glass, or as though the aliveness of their experience has been lost. At the more serious end of the spectrum, when dissociation is connected with traumatic experiences or with chronic difficulties in regulating the nervous system, it takes on a different intensity and quality.
At the core of many traumatic experiences lies dysregulation of the nervous system. Trauma disrupts a person’s capacity to stay within a range in which feelings are tolerable and can be processed without flooding the psyche. Daniel Siegel describes this range as the “window of tolerance”. When a person is within it, they can stay in contact with themselves, their feelings and their environment. But when an experience exceeds their capacity to process it, the nervous system may move either towards hyperarousal (anxiety, panic, tension, hypervigilance) or towards hypoarousal (numbness, collapse, withdrawal and dissociation).
Dissociation can be understood as an attempt by the organism to prevent consciousness from being overwhelmed when an experience is too intense or unbearable. From this perspective it is not pathology from the outset, but a remarkably intelligent protective mechanism. It becomes problematic when a person cannot control when and how it appears, or when the mechanism generalises and is activated even in situations that involve no real danger.
Dissociation may involve a generalised distancing from experience, or it may be activated in particular environments, relationships or situations. People who dissociate systematically often struggle to stay in contact with their sensations, feelings and bodily reactions. They may lose their sense of time, find it hard to remember specific events, or feel that what is happening concerns someone else and not them.
Dissociation is also often expressed as a distancing from the body. Someone may find it hard to recognise hunger, tiredness, tension, the need for rest, or even their own boundaries in relationships. Since the body is a fundamental carrier of experience, reconnecting with sensations and bodily reactions is often an important part of the therapeutic process.
When a traumatic experience has preceded it, especially in childhood, dissociation may function as the only available means of survival. The sense that what is happening is not real, the cutting off from feelings, or even the distancing from the body can protect a person from an experience that at that moment exceeds their capacity to bear it.
However, significant traumatic events are not required for dissociation to appear. Often it is not the present event that triggers it, but the fact that the present situation activates earlier experiences of overload, helplessness, rejection or emotional loneliness. Besides traumatic events that happen suddenly, dissociation can also be connected with developmental or relational trauma — that is, with experiences that were repeated within the significant relationships of a person’s life.
A young client began experiencing episodes of derealisation during a period of increased professional demands. The episodes appeared more often when she was in crowded places or when she felt she had to be constantly available to others, setting aside her own needs. The symptoms receded when she returned home, rested, and felt that nothing was being asked of her. Although the trigger appeared to be everyday pressure, therapeutic exploration revealed that these situations were activating a deeper experience of over-adaptation and of losing contact with herself.
From a relational perspective, dissociation is not only about moving away from painful feelings. It often also concerns parts of the self that once found no space to be recognised or accepted within significant relationships. Feelings, needs or desires that could not be understood and emotionally shared may gradually be cut off from awareness as a way of adapting to the relational environment.
From an existential perspective, dissociation can also be seen as a distancing from the authentic experience of existence. Heidegger described the way people often live according to the expectations of others rather than according to their own truth. When life is organised around what we “ought” to be, when we avoid the responsibility of our choices, or when we move away from our deeper desires, a sense of emptiness, estrangement or unreality can appear. In this sense, certain forms of dissociation can be seen not only as a response to trauma but also as an expression of a distancing from an authentic relationship with the self.
In Gestalt psychotherapy, dissociation can be understood as an interruption of contact — with others, and also of the living connection with the body, feelings, needs and environment. A person stops fully perceiving what they feel, what they need, or what is happening in their relationships. Experience thus loses its aliveness, its clarity and its immediacy.
Dissociation can express an inner withdrawal at the very moment when a person would need to withdraw from an external situation, assert a boundary, express a need, or protect themselves within a relationship. Instead of moving away from what is burdening them, they move away from their own experience.
The aim of psychotherapy is not to abolish dissociation by force but to understand its function. As a person gains more safety, awareness and capacity for regulation, this mechanism stops being the only available solution. Then continuous contact with experience, with the body, with feelings and with others can gradually become more bearable and more authentic.
