What Does EMDR Actually Feel Like During a Session? A Trauma Therapist’s Honest Guide

HEALING MODALITIES & THERAPEUTIC PROCESS • April 14, 2026

LAST UPDATED: APRIL 2026

The Light Bar, the Leather Chair, and the Dread She Didn’t Expect

Camille sat in the leather chair in her therapist’s office and stared at the small device on the desk in front of her. It looked, she would tell me later, like something from a dental waiting room — a thin horizontal bar, a row of small LED lights, a cord disappearing into a laptop. The room smelled faintly of cedar. Her hands were folded in her lap with the careful precision she usually reserved for board presentations.

She was a forty-one-year-old executive director at a foundation in San Francisco. She had done years of talk therapy. She had read Bessel van der Kolk, MD’s The Body Keeps the Score twice. She understood, intellectually, that trauma lives in the body. She had made the appointment, driven herself across the bridge, paid out of pocket — and now she was sitting here staring at a light bar and feeling something she hadn’t quite anticipated: not fear, exactly. Something closer to dread. (PMID: 9384857)

Not dread of the process failing. Dread of what it might do. Dread of losing the grip she had maintained, carefully, for nearly four decades on the part of herself that didn’t get discussed in meetings, that didn’t appear on her résumé, that she’d spent her entire career burying under competence and ambition and forward motion.

“I don’t want to cry in front of someone and not be able to stop,” she told me, describing that first session. “That’s my real fear. Not that it won’t work. That it will.”

In my work with clients, this is one of the most honest things someone can say before beginning trauma-focused therapy. And it tells me something important: Camille wasn’t ambivalent about healing. She was ambivalent about the particular shape of surrender that healing requires. That ambivalence — that intelligent, well-defended resistance — is worth taking seriously. It’s also worth understanding the process clearly enough to move through it with intention rather than anxiety.

So let’s talk about what EMDR actually feels like. Not in abstract clinical terms. In the specific, embodied, sometimes-strange, sometimes-profound terms of what happens in the room, in your body, in the hours and days after a session, and across the arc of a full course of treatment.

What Is EMDR, Really?

Before we can talk about sensation, we need to be precise about the modality itself — because EMDR is frequently misunderstood, often caricatured, and sometimes frightening to people who encounter it without context. The fear is understandable. The name is clinical and strange. The mechanism looks, from the outside, almost theatrical.

Francine Shapiro, PhD, who spent decades refining and researching the protocol before her death in 2019, was careful to describe EMDR not as a technique but as a complete psychotherapy — one grounded in a coherent theoretical model of how trauma disrupts the brain’s natural capacity to process and integrate experience.

That model is called the Adaptive Information Processing model, or AIP. Understanding it changes how you experience the process. Instead of feeling like something is being done to your brain, you begin to feel like something is being freed within it.

For women who have done talk therapy for years, this distinction often lands with a specific kind of relief. Talk therapy is extraordinary for many things — building insight, developing coping skills, understanding relational patterns. But insight, as Bessel van der Kolk, MD, psychiatrist and trauma researcher at the Trauma Center at Justice Resource Institute and author of The Body Keeps the Score, has made clear through decades of neuroimaging research, does not on its own change the neural encoding of a traumatic memory. You can understand, intellectually, that you are safe. Your amygdala may not agree. EMDR works at the level where that disagreement actually lives.

What does that level feel like to access? That’s what the rest of this post is about.

The Neurobiology Behind the Eye Movements

One of the most common questions I hear is some version of: “But why eye movements? Why does that do anything?” It’s a fair question. The mechanism can look almost absurdly simple from the outside — your therapist moves their fingers back and forth, or you follow a light bar, or you hold small buzzers in your hands. What could that possibly have to do with processing trauma that’s been stored in your nervous system for years?

The honest answer is that researchers are still refining the full neurobiological explanation. But the leading hypothesis — and one with substantial supporting evidence — involves a process analogous to what happens during REM sleep.

During REM sleep, your eyes move rapidly from side to side. Simultaneously, the brain is doing essential work: consolidating memories from the day, processing emotional experiences, integrating new learning into existing neural networks. Neuroimaging studies suggest this process involves coordinated activity between the hippocampus (which contextualizes and files memory) and the amygdala (which tags experiences with emotional significance). When you’re traumatized and struggling with sleep — which most trauma survivors do — this nightly processing is disrupted. The consolidation doesn’t happen properly.

Bilateral stimulation during EMDR appears to activate a similar process while the person is awake, alert, and anchored in the present moment. The back-and-forth movement — whether it’s your eyes tracking a light, your hands feeling alternating vibrations from tappers, or your ears receiving alternating tones — seems to reduce the emotional intensity of the memory being held in mind while simultaneously facilitating its integration into a more adaptive neural network.

Judith Herman, MD, psychiatrist at Harvard Medical School and author of Trauma and Recovery, the foundational clinical text on trauma treatment, articulated the challenge that EMDR speaks directly to: that traumatic memories are stored differently from ordinary memories. They lack narrative context. They feel, to the brain, less like “something that happened once in the past” and more like “something that is continuously happening.” The bilateral stimulation in EMDR appears to help the brain shift traumatic material from its original hyperactivated, unintegrated storage into the kind of narrative, time-stamped memory that ordinary experience lives in. (PMID: 22729977)

This is why, at the end of successful EMDR processing, the memory hasn’t disappeared. You still know it happened. But it’s lost its grip — its heat, its urgency, its capacity to hijack your nervous system in the present moment.

Roger Solomon, PhD, psychologist and senior trainer at the EMDR Institute, whose work on EMDR for grief and loss has extended the protocol into complicated mourning processes, describes this shift as the memory moving from “raw wound” to “scar.” The scar is still part of you. It’s no longer actively bleeding.

A Session-by-Session Walkthrough: What to Expect

Most descriptions of EMDR focus on the protocol phases in abstract clinical terms. What’s harder to find — and what my clients consistently say they wish they’d had before starting — is a concrete, honest account of what the process feels like from the inside, week by week.

Here’s what I can tell you, based on both the research and my clinical experience working with driven women through this process.

Phase 1: History-taking and Treatment Planning (typically 1–3 sessions)

The first sessions look more like an extended intake than anything resembling the EMDR you’ve read about. Your therapist is gathering a detailed history — not just of the trauma you’re coming to address, but of your full psychological landscape: attachment history, other significant memories, current triggers, your window of tolerance, your capacity to self-regulate. This phase can feel slow if you’re eager to get into “the real work.” It isn’t slow. It’s the foundation.

What this feels like: a thorough, sometimes emotionally activating conversation. You might notice your body responding to certain memories even as you describe them clinically. Your therapist is watching for this — those involuntary shifts in posture, breath, voice tone — because they are useful clinical information about where the work will eventually need to go.

Phase 2: Preparation (often woven into early sessions)

Before any bilateral stimulation begins, your therapist will teach you stabilization skills. These are the anchors you can use if the processing becomes too intense — both during sessions and between them. Common tools include the Safe Place or Calm Place visualization (a detailed imagined location where you feel completely secure), the Container (mentally placing distressing material in a bounded space for later), and various grounding techniques for reconnecting with the present moment.

For driven women, this phase can be quietly frustrating. It feels like being given a tutorial before you’re allowed to open the software. But the stabilization skills are not filler — they’re what make the processing phases safe. And they’re what you’ll reach for at 2 a.m. between sessions when something unexpected surfaces.

Phase 3: Assessment (beginning of each processing session)

When processing begins, each session starts with the same structured questions: What image represents the worst part of the memory? What negative belief about yourself goes with that image right now (common examples: “I’m not safe,” “I’m powerless,” “I’m worthless,” “I’m to blame”)? What would you prefer to believe about yourself instead? What emotions do you notice, and where do you feel them in your body? And on a scale of zero to ten, how disturbing does the memory feel right now?

That last rating — the Subjective Units of Distress Scale, or SUDS — becomes a compass for the session. You’ll be asked to rate again after each set of bilateral stimulation. Watching the number drop, often in unexpected jumps, is one of the stranger and more clarifying experiences in EMDR.

Phase 4: Desensitization (the heart of EMDR processing)

This is the phase that’s most associated with EMDR in the popular imagination, and the one that most needs demystifying. Your therapist asks you to hold the target memory in mind — the image, the negative belief, the body sensations — and then begins the bilateral stimulation.

The light bar starts moving. Or the buzzers in your hands begin to pulse, left-right, left-right. And you are asked, essentially, to notice what happens.

What most people expect: a dramatic emotional release, or nothing at all. What most people actually experience is something subtler and stranger than either. The memory shifts. Not linearly, not predictably. Thoughts arise, seemingly at random — a childhood scene you hadn’t thought of in years, a phrase someone said once, a physical sensation in your chest or throat, a sudden and unexpected wave of something that might be sadness or might be relief. You notice these things without being asked to analyze them. Your therapist checks in briefly between sets of stimulation: “What do you notice now?” You report it. The next set begins.

This is the core movement of EMDR processing, and it continues until the SUDS rating reaches zero or one — until the memory no longer carries its original emotional charge.

Phases 5–7: Installation, Body Scan, and Closure

Once desensitization is complete for a given memory, the therapist helps you install a positive cognition — the belief about yourself you want to carry instead. This happens through more bilateral stimulation, this time focused not on distress but on strengthening. You hold the memory and the new belief simultaneously and rate how true the belief feels on a scale of one to seven. The session closes with a body scan: holding the original target in mind while you scan from head to toe, noticing any residual physical tension. Whatever remains is processed further. Then you’re returned, deliberately, to a state of present-moment calm before you leave the room.

Phase 8: Reevaluation

Every subsequent session begins here — checking what has settled from the last session, what has shifted, what might have surfaced. New material often emerges between sessions. The reevaluation phase makes space for that.

The Body During Processing: Common Sensations and Reactions

The most asked and least answered question about EMDR is this one: “But what does it actually feel like in my body while it’s happening?”

Here’s what my clients consistently report, and what I’ve seen replicated in the clinical literature:

During desensitization sets, many people experience involuntary physical sensations: warmth spreading across the chest or face, a loosening in the throat, the urge to take a deep breath that comes without trying. Some notice tingling in the extremities, or a wave of heaviness in the limbs, or a sudden release of tension in the jaw or shoulders that they hadn’t realized was there. These are signs that the nervous system is shifting — that the freeze or bracing that has been holding the memory in place is releasing.

Some people cry, not dramatically but quietly — tears that arise without the usual narrative of grief attached to them. Some feel unexpected anger surface. Some feel nothing for the first few sessions and then, unexpectedly, a great deal all at once. All of these are within the range of normal.

Between sessions, EMDR processing continues. This is not a metaphor — it’s a neurological reality that surprises many people who expect the work to stay inside the therapy room. In the days following a processing session, you might notice: vivid dreams (sometimes related to the material being processed, sometimes apparently random), unexpected emotional shifts, memories surfacing that you’d filed away, a heightened sensitivity to things that would ordinarily not affect you, or conversely, a strange sense of lightness or clarity about something that used to feel heavy.

This is why EMDR therapists ask you to keep a brief log between sessions — not a journal of deep analysis, but simple notes about what you notice. What came up. What shifted. What surprised you. This log becomes essential clinical material for the reevaluation phase that opens the next session.

Nadia was a family medicine physician in her late thirties who had started EMDR to process a series of traumatic experiences from her residency — the specific kind of institutional trauma that accumulates in medical training and doesn’t get named as such until years later. She’d been skeptical going in. She described the mechanism as “too simple to be real.” After her third processing session, she texted her husband from the parking lot: “I just cried about something that happened seventeen years ago and I feel like I lost five pounds.”

She meant it as a half-joke. But she told me in our next session that the image that had felt, in every prior telling of the story, like a stone in the center of her chest — her attending’s face, the fluorescent lights, the words “if you can’t handle this, you’re in the wrong field” — had lost something. She could still picture it. She knew it was real. But when she brought it to mind, the stone was gone. There was something else there — she called it “just a fact.” Something that happened. Something she’d survived. Something that no longer had its hands around her throat every time she was on call and something went wrong.

“I kept waiting for it to come back,” she told me. “Like maybe I’d just had a good week and the next session it would all be there again.” It didn’t come back. That’s not magic. That’s what successful EMDR processing actually looks like.

Both/And: EMDR Is Strange and It Works

One of the most honest things I can say about EMDR is this: it can feel bizarre, even a little absurd, in the early sessions. You’re sitting in a therapy office, holding buzzers or following a light bar, being asked to recall the worst things that have ever happened to you, and the instruction is essentially: “Just notice what comes up.” There’s no discussion. No analysis. No narrative to construct. Just you, the bilateral stimulation, and whatever your nervous system decides to do next.

For women who have been rewarded throughout their lives for explaining themselves well — for making things make sense, for turning experience into language, for demonstrating mastery through articulation — this can feel like being handed a task with no rubric. There’s nothing to get right. There’s nothing to perform. The instruction is simply to let the process happen, and then report what you noticed.

Camille, the executive director from San Francisco, described her third session as “like trying to take a nap at a corporate retreat. My brain kept asking what the goal was.” She’d spent the first two sessions watching the light bar with the polite, focused attention she brought to conference calls. In the third session, her body did something she hadn’t planned: her hands started shaking during a set of eye movements, and for a moment she was back in a kitchen she hadn’t thought about in thirty years. The shaking passed. The image passed. Her SUDS dropped from an eight to a three in a single set.

“Nothing about that makes sense to me,” she told me afterward. “And I also can’t argue with what just happened to the number.”

Both things are true simultaneously. EMDR doesn’t fully reveal its mechanism while you’re in it. The research supports it; the body confirms it. You don’t have to understand it for it to work. And the fact that it’s strange doesn’t mean it isn’t also profound. Many of my clients describe specific moments in EMDR processing as among the most significant experiences of their therapeutic lives — not because they were dramatic, but because something actually changed. Something that had been fixed came loose. Something that had been loud went quiet.

This both/and experience — “this feels weird and this is working” — is worth naming explicitly, because the strangeness of the early sessions can become a reason to stop if you haven’t been prepared for it. You don’t have to be comfortable for EMDR to be effective. You have to be safe, resourced, and willing to stay inside the window of tolerance while the process unfolds.

And the complex relational trauma that many driven women carry often means that window of tolerance needs careful tending before processing can begin in earnest. This is exactly why the preparation phase isn’t optional. It’s what makes the strangeness navigable.

The Systemic Lens: Why Driven Women Often Resist Surrendering Control

There is a specific way that EMDR can feel threatening to women who have built their lives — their survival, in some cases — around maintaining cognitive control. I want to name this directly, because it’s not a character flaw or a sign of psychological limitation. It’s a coherent adaptation to the systems they’ve had to navigate.

Judith Herman, MD, observed in Trauma and Recovery that for many trauma survivors, the maintenance of control over one’s inner life is not rigidity — it’s strategy. When your external environment has been unpredictable, chaotic, or dangerous, the ability to manage your own internal states becomes a life skill. The problem is that this strategy, so useful in the original environment, becomes a barrier in the therapeutic one. Because EMDR asks you to let go of cognitive control in a very specific way: to stop managing what comes up and simply allow the processing to happen.

For women who lead organizations, who manage complexity across multiple domains, who are accustomed to being the most regulated person in any difficult room — this instruction can feel physiologically threatening, even when the conscious mind fully understands why it’s being given.

The culture compounds this. Ambitious women who have accessed mental health treatment at all have typically done so in culturally sanctioned forms: the kind of therapy where you talk, analyze, gain insight, and demonstrate understanding. EMDR’s demand for cognitive non-interference — for essentially sitting with the experience rather than explaining it — runs counter to what many women have been implicitly taught “doing the work” should look like. Work requires effort. Work requires articulation. Work, in many cultural frameworks for women, requires being visibly productive.

EMDR processing can look, from the outside, like nothing much is happening. The client is quiet. The therapist is quiet. The light moves back and forth. And inside, the nervous system is doing the most significant reorganization it may have undertaken in years.

Bessel van der Kolk, MD, has written and lectured extensively about the way Western therapeutic culture privileges verbal, cognitive processing modes that can actually bypass the subcortical structures where traumatic memory lives. Talking about trauma can activate the prefrontal cortex while leaving the amygdala and body entirely unaddressed. EMDR reaches both. For many driven women, accessing the body in a therapeutic context at all — following it, trusting its signals, allowing it to move the process rather than overriding it with cognition — is itself a significant developmental step.

I also want to name something about childhood emotional neglect and its relationship to this pattern. Many of the women who come to individual therapy having built these formidable control strategies grew up in environments where losing emotional control was genuinely dangerous — where tears were weaponized, where vulnerability was punished, where staying regulated meant staying safe. When those women sit down to begin EMDR and feel the specific dread that Camille named — “what if I cry and can’t stop” — they aren’t being dramatic. They’re reporting a real historical threat. And part of the preparation work in EMDR is creating enough safety in the therapeutic relationship that the nervous system can begin to update that threat assessment.

This is also why EMDR is not a solo project. The bilateral stimulation doesn’t work in a vacuum — it works within a relational context. The safety of the therapeutic relationship is the container that makes the processing possible. Francine Shapiro, PhD, was explicit about this in her foundational writing: the eight-phase protocol is not a mechanical sequence applied to a body; it’s a structured intervention delivered within a human relationship characterized by trust, attunement, and collaborative meaning-making.

If you’re in trauma-informed therapy and the therapeutic relationship doesn’t feel safe enough yet to risk this kind of vulnerability — that’s important clinical information. Tell your therapist. The preparation phase exists for exactly this reason.

What Comes Next — and How to Get the Most from the Process

EMDR isn’t a one-session fix, and it doesn’t follow a perfectly linear arc. In my clinical experience, the course of EMDR for complex relational trauma typically unfolds in layers — early sessions often address more recent or more contained memories, with deeper developmental material becoming accessible as the nervous system builds its capacity to tolerate the process.

What I tell clients before they begin:

Protect the 24 hours after a processing session. Your nervous system will be in an active integrative state. This isn’t the time for a full social calendar, a high-stakes presentation, or a difficult conversation with a family member. Build in room to be tired, reflective, or mildly emotionally sensitive. This isn’t weakness — it’s respecting the biology of what just happened.

Use your stabilization skills, not avoidance. If something surfaces between sessions that feels big, reach for what your therapist has taught you — the container, the calm place, the grounding techniques — rather than numbing or pushing through. The material belongs in the session. It’s there to be processed, not pre-managed.

Don’t analyze the process while you’re in it. This is the specific instruction that most driven women find hardest. The urge to understand, to explain, to construct a narrative around what is happening is powerful. EMDR works precisely by bypassing that urge. You can analyze later. During the set of bilateral stimulation, your only job is to notice and report.

Expect the unexpected. EMDR processing surfaces associated material — memories, images, beliefs, body sensations — that you didn’t anticipate and often wouldn’t have predicted are related to the target memory. They almost always are related. The adaptive information processing system has its own logic, and it’s more trustworthy than your conscious editorial judgment about what does and doesn’t belong.

Roger Solomon, PhD, writes about this process in the context of grief, noting that EMDR allows the mourner to eventually access not just the pain of loss but the full, textured emotional archive of the relationship — the warmth, the humor, the complicated love — that acute grief has made temporarily inaccessible. Something similar happens in the processing of relational trauma: what often emerges, after the charge of a difficult memory has been cleared, is not emptiness but complexity. A more complete picture. A self that has room for the full truth of what happened.

For women who have survived difficult things by keeping the narrative clean and tight — by becoming extraordinary at telling the manageable version of the story — this expanding, more textured relationship with their own history can feel like the most significant gift the process offers.

If you’re wondering whether EMDR is appropriate for your particular history, the first step is an honest conversation with a trauma-informed therapist trained in the modality. Not every traumatic presentation requires EMDR. Not every client is ready for EMDR as a starting point. But for women who have done significant talk therapy work and still find themselves activated by things they understand — still responding to old material with nervous system states that don’t match the present reality — EMDR is often the intervention that finally reaches what the words couldn’t.

It’s not about giving up cognitive control. It’s about discovering that your nervous system, given the right conditions, knows how to complete the work it has always been trying to do. EMDR creates those conditions. And what follows, as Nadia found in a parking lot after her third session, and as Camille found four months into processing that she didn’t quite have language for yet, is something that starts to feel like — finally, genuinely, not as a metaphor — relief.

If you’re ready to explore what this kind of work might look like for you, I’d invite you to schedule a consultation, take the free quiz to understand the underlying patterns, or join the Strong & Stable newsletter, where I write weekly about exactly this kind of terrain — what healing actually looks like for ambitious women who are finally ready to let it.
