You are mid-session and something shifts. The client was describing an argument with their mother, and now their voice has gone flat. Their eyes are fixed somewhere past your shoulder. When you ask what they are noticing, there is a long pause, and then a quiet answer: “I don’t know. I wasn’t really here for a second.”
Most therapists have met this moment. Some recognize it immediately. Others only realize later that a client has been drifting in and out of contact for months, and that the treatment has been talking to a part of the person while another part waits somewhere out of reach. Dissociation is common, it is often subtle, and it changes what good therapy needs to look like.[1][2]

What dissociation is, and why it exists
Dissociation is a disruption in the normal integration of consciousness, memory, identity, emotion, perception, and behavior. That is the clinical definition. In the room, it looks like a person becoming disconnected from their body, their feelings, their surroundings, or their sense of who they are.[2][3]
It exists on a continuum. Almost everyone dissociates mildly: highway driving on autopilot, losing an hour in a book, walking out of a stressful meeting with no memory of the hallway. At the other end sit the dissociative disorders, where disconnection is frequent, involuntary, and disruptive enough to interfere with relationships, work, and safety.[3][2]
The most important frame for clinicians is that dissociation is protective. It usually develops as a survival response to experiences that were overwhelming and inescapable, most often chronic childhood trauma, neglect, or abuse. When a child cannot fight or flee, the nervous system finds another exit: it leaves internally. What was adaptive then becomes automatic later, firing in situations that are stressful but no longer dangerous.[1][2][4]
Recognizing dissociation in the room
Assessment begins with tracking, not with a questionnaire. Dissociation announces itself in small ways. A client’s gaze goes distant or glassy. The voice flattens or shifts register. They lose the thread mid-sentence and cannot find it again. They report watching themselves from outside, or say the room looks foggy or far away. Some clients describe gaps: they cannot account for how they got somewhere, or a whole conversation is simply missing.[2][3]
Many clients will not volunteer these experiences. Some assume everyone lives this way. Others fear sounding crazy. This is why direct, normalizing questions matter. Asking “Do you ever lose time?” or “Do you ever feel like you’re watching yourself from outside your body?” often opens material that years of open-ended talk never touched.[1][2]
It also helps to know what dissociation can hide behind. It is frequently mistaken for inattention, resistance, low motivation, or a mood disorder. A client who “spaces out” may be labeled ADHD. A client who goes numb during exposure work may be described as not engaging. Screening for dissociation before beginning any trauma-focused treatment protects both of you from working on material the client is not actually present for.[1][5]
Structured assessment tools
Clinical observation can be supported with validated instruments. The Dissociative Experiences Scale (DES-II) is a widely used self-report screen that gives a quick sense of how much dissociation is part of a person’s daily life. High scores are not diagnostic on their own, but they signal that a more careful evaluation is warranted.[2][6]
For diagnosis, structured interviews such as the SCID-D (Structured Clinical Interview for Dissociative Disorders) and the Multidimensional Inventory of Dissociation (MID) allow a clinician to differentiate between depersonalization-derealization disorder, dissociative amnesia, and dissociative identity disorder, and to distinguish dissociative presentations from psychosis, seizure disorders, and substance effects. Medical causes should always be considered and ruled out where indicated.[1][2][3]
Good assessment is also ongoing. Dissociative clients often present differently across sessions, and a picture that looked like straightforward PTSD in month one may reveal more complexity in month six. Guidelines from the International Society for the Study of Trauma and Dissociation encourage clinicians to hold diagnoses lightly and revise them as trust deepens and more of the client’s inner world becomes visible.[1]
Treatment: phase-oriented, paced, and respectful
Psychotherapy is the core treatment for dissociative disorders. Medication has a role only for co-occurring conditions such as depression, anxiety, or sleep disturbance. There is no medication for dissociation itself.[2][3]
The most widely accepted framework is phase-oriented treatment, reflected in the ISSTD adult treatment guidelines. Phase one is safety and stabilization: building the therapeutic relationship, establishing daily-life stability, teaching grounding and regulation skills, and helping the client recognize their own dissociative shifts. Phase two is the careful processing of traumatic material, undertaken only when the client can stay within a tolerable range of activation. Phase three is integration and reconnection, where the gains are woven into ordinary life, relationships, and identity.[1][4]
The order matters. One of the most common clinical errors with dissociative clients is moving into trauma memories too early. Processing work that outpaces stabilization tends to increase dissociation rather than resolve it, and it can rupture the treatment. Slower is genuinely faster here.[1][5]
Within this frame, several approaches are commonly used. Parts-oriented work helps clients develop communication and cooperation among self-states rather than forcing premature integration; the guidelines are explicit that all parts deserve respect and that fusion is an outcome, not a technique. Trauma-focused cognitive and dialectical behavior therapy skills can support emotion regulation when adapted for dissociation. EMDR can be effective, but it requires dissociation-sensitive modifications: extended preparation, smaller targets, more titrated exposure, and constant attention to present-time orientation.[1][5][7]
A somatic lens on dissociation
From a body-based perspective, dissociation is a nervous system strategy. Awareness pulls away from sensation because sensation was once unbearable. This is why purely cognitive work often stalls with dissociative clients: the disconnection is not a belief that can be argued with. It lives underneath language. For an introduction to how body-based approaches work with these patterns, see Embodywise’s Somatic Therapy overview.[8][9]
Somatic treatment of dissociation is quiet and incremental. It usually starts with orienting: inviting the client to look around the room, name what they see, feel the chair under them, sense their feet on the floor. These are small acts of returning. Over time the work expands to brief, tolerable contact with inner sensation, always with the client’s consent and always with an exit available.[8][9]
Two principles guide the pacing. Titration means touching difficult material in small doses rather than diving in. Pendulation means moving between activation and settledness, so the nervous system learns that it can approach what hurts and come back. Both principles keep the work inside the window of tolerance, which is precisely the range that dissociation exists to escape. When the range widens, the need to leave the body softens.[9][8]
The therapist’s own body is part of this method. Dissociative clients are exquisitely sensitive to the state of the person across from them, and a grounded, unhurried presence is itself an intervention. Mindfulness-centered approaches such as Hakomi train exactly this capacity: tracking present-moment experience, contacting it gently, and studying what the client’s system does with attention rather than pushing it anywhere. Embodywise’s Hakomi Overview, Trainings and Workshops describes this orientation in more depth.[8]
What to hold with extra care
A few cautions are worth naming plainly. Do not pursue memory recovery as a goal; the aim is integration of experience, not archaeology, and suggestive techniques carry real risk. Do not treat dissociation in session as failure, in the client or in yourself; it is information about pacing. Watch for your own responses too, because sitting with dissociation can pull a therapist toward drowsiness, fogginess, or urgency, and noticing that pull is part of the assessment.[1][5]
Expect the work to be long. Severe dissociative disorders typically require years rather than months, and progress is measured in functioning and quality of life, not in dramatic breakthroughs. Clients who learn that their therapist will not push them past their edge tend to come back, risk more, and slowly need the old exits less.[1][2]
For practitioners who want structured, trauma-informed training in this territory, including nervous system regulation, titration, and working with survival responses in the body, the ISITTA Trauma Therapy Training at Embodywise offers a dedicated pathway for building these skills with support for your own nervous system along the way.
