If you’ve been told that EMDR therapy might help you, your first question is probably a practical one: what actually happens in the room? That’s a fair thing to want to know before you commit to anything. EMDR (Eye Movement Desensitization and Reprocessing) follows a structured eight-phase protocol, and understanding those phases ahead of time can make the whole process feel a lot less uncertain. This post walks through each phase in plain language, from the first conversation your therapist has with you to what reprocessing actually feels like in the moment, including the parts most introductory descriptions skip over.
Why EMDR sessions feel different from regular talk therapy
Most people walk into a first EMDR session expecting something close to what they’ve seen on TV: a couch, a box of tissues, a therapist asking “and how did that make you feel?” EMDR is structured differently, and that difference surprises people who aren’t prepared for it.
In a standard talk therapy session, the conversation tends to move wherever it moves. You might spend 45 minutes on something that came up that morning. EMDR sessions are more deliberate. Your therapist is working through a specific protocol, and each session has a purpose within a larger sequence. Some sessions involve no reprocessing at all. Early sessions are entirely about history, assessment, and preparation. This isn’t a slow start or a delay, it’s the foundation that makes reprocessing safe and effective.
The other thing that surprises people: EMDR doesn’t require you to talk through your trauma in detail. You don’t have to narrate what happened. You hold the memory internally while your therapist guides bilateral stimulation (usually eye movements, taps, or tones), and the processing happens largely without words. For people who have tried to talk about their trauma and found it re-traumatizing, this is often a relief. For people who expected to talk, it can feel disorienting at first.
Knowing this going in helps. You’re not doing something wrong if a session feels quiet or internal. That’s often exactly what’s supposed to be happening.
Phase 1 and 2: What happens before any reprocessing begins in an EMDR session
The first two phases of EMDR are sometimes called the “preparation phases,” and they take longer than most people expect. Depending on your history and how complex your trauma is, preparation can span several sessions before any reprocessing begins.
Phase 1: History-taking and treatment planning
Your therapist will spend significant time in early sessions understanding your history. This isn’t just a formality. They’re identifying which memories are driving your current symptoms, assessing your capacity to tolerate distress, and mapping out a treatment plan. They’ll ask about your sleep, your support network, what brought you in, and what your life looks like day to day. They’re also watching for factors that might require extra care, such as dissociation, active crisis, or medical conditions that could affect how you respond to reprocessing.
Phase 2: Preparation and stabilization
Before touching any traumatic material, your therapist will teach you stabilization skills. These are specific techniques, like a “calm place” visualization or a containment exercise, that you can use if you become overwhelmed during or between sessions. This phase also includes a clear explanation of how bilateral stimulation works and what to expect. A common misconception is that this phase is just “getting comfortable.” It’s actually clinical groundwork. A client who doesn’t have reliable stabilization skills isn’t ready for reprocessing, and a good EMDR therapist won’t rush past this.
Phase 3: How your therapist identifies the right target memory
Phase 3 is called “assessment,” and it’s more precise than it sounds. Your therapist isn’t just asking “what do you want to work on?” They’re using a structured process to identify the specific memory to target, the image that represents the worst part of it, the negative belief you hold about yourself because of it (called a “negative cognition”), and what you’d rather believe instead (the “positive cognition”).
You’ll also rate how true the positive belief feels right now on a scale of 1 to 7 (the Validity of Cognition scale, or VoC), and how distressing the memory feels on a scale of 0 to 10 (the Subjective Units of Disturbance scale, or SUD). These aren’t just intake forms. Your therapist will return to these numbers throughout treatment to track whether reprocessing is actually moving.
One thing worth knowing: the “target memory” isn’t always the most dramatic event in your history. Sometimes the memory driving the most distress is something that looks small from the outside, a moment of humiliation, a time someone didn’t show up, a childhood incident that seems minor but left a lasting imprint. Your therapist is trained to identify these, and you don’t need to second-guess the choice. If a memory feels significant to you, that’s information worth bringing in.
Phases 4 through 6: What reprocessing actually feels like during an EMDR session
This is the part people are most curious about, and also the part that’s hardest to describe from the outside.
In Phase 4 (desensitization), you hold the target memory in mind while your therapist guides bilateral stimulation. This might be a light bar you follow with your eyes, headphones with alternating tones, or taps on your knees or hands. Sets of stimulation typically last 20 to 30 seconds, followed by a brief check-in. Your therapist will ask something like “what do you notice?” and you report whatever comes up, an image, a feeling, a thought, a body sensation, or nothing at all. Then another set begins.
What happens during those sets varies widely. Some people experience a clear shift, like watching a film reel of connected memories. Others feel physical sensations, tightness in the chest that gradually releases, for example. Some sessions feel like nothing is happening, and then something shifts at the end. There’s no single “right” experience.
Phase 5 (installation) strengthens the positive cognition once distress has reduced. Phase 6 (body scan) checks for any residual tension held in the body. Both are brief but important. A session that ends at Phase 4 without completing the body scan is considered incomplete, and your therapist will note that for the next session.
Phase 7: How EMDR sessions close, even incomplete ones
Every EMDR session ends with a closure phase, whether or not reprocessing is complete. This is non-negotiable in the protocol, and it’s one of the things that distinguishes well-trained EMDR therapists from those who’ve had only surface-level exposure to the method.
If a session ends with disturbance still present (SUD above 0), your therapist will use a containment technique to help you leave the session in a stable state. This might be a visualization where you “store” the unfinished material in an imaginary container until the next session. It sounds abstract, but it serves a real clinical purpose: you need to be able to drive home, go back to work, or pick up your kids after a session. Leaving someone in an activated state is a clinical error.
Your therapist will also give you a brief log to keep between sessions. You might notice new memories, dreams, or thoughts that surface in the days after reprocessing. This is normal and expected. The log helps you capture these without getting pulled into them, and it gives your therapist useful information for the next session.
An edge case worth knowing: if you’re in a particularly demanding period of life (a custody hearing, a major work deadline, a family crisis), your therapist may choose to pause active reprocessing and focus on stabilization instead. EMDR is flexible enough to accommodate this, and a good therapist will make that call with you, not for you.
What EMDR therapist credentials actually mean, and why they matter
Not everyone who offers EMDR has the same level of training, and this matters more than most people realize when they’re choosing a therapist.
Basic EMDR training is a weekend course. It provides an introduction to the protocol, but it doesn’t make someone an EMDR specialist. The gold standard credential is EMDRIA Certification, issued by the EMDR International Association. To earn it, a therapist must have at least two years of post-licensure experience, complete a minimum of 50 EMDR sessions with at least 25 clients, and receive 20 hours of consultation from an EMDRIA Approved Consultant (at least 10 of those hours must be individual). They also need 12 hours of EMDRIA-approved continuing education credits. [S1]
Above that sits the EMDRIA Approved Consultant credential, which is the highest designation EMDRIA offers. [S2] One thing to watch for: letters of support from EMDRIA Consultants-in-Training do not meet the certification requirement. Only letters from full Approved Consultants count. [S3]
When you’re looking for an EMDR therapist, it’s reasonable to ask about their training and whether they hold EMDRIA Certification. You can also check Wholetherapy’s FAQ for more on how credentials work and what to ask a prospective therapist.
Practical things to know before your first EMDR session in Nova Scotia
A few logistical realities that don’t always make it into the clinical descriptions.
EMDR sessions are typically 60 to 90 minutes. The longer format matters because reprocessing that starts in a session needs time to reach a stable stopping point. A 50-minute session can work for preparation phases, but active reprocessing often benefits from more time. Ask your therapist what session length they use and why.
Between-session experiences are real and can be intense. After a reprocessing session, some people notice that memories, emotions, or physical sensations surface in the days that follow. This isn’t a sign that something went wrong. It’s often a sign that processing is continuing. Your therapist will prepare you for this and give you tools to manage it.
If you’re considering EMDR therapy and you’re not sure whether it’s the right fit for your situation, that’s a conversation worth having before you commit to a full course of treatment. Wholetherapy offers consultations where you can ask exactly these kinds of questions. You can contact us to set one up.
One honest note: EMDR is not the right approach for everyone. People with significant dissociation, active psychosis, or certain medical conditions may need a different approach or a modified protocol. A thorough Phase 1 assessment is partly designed to identify this. If EMDR isn’t the right fit, a good therapist will tell you that directly rather than proceed anyway.
Frequently asked questions
How many EMDR sessions will I need?
There’s no universal answer, and anyone who gives you a firm number before doing a thorough assessment is guessing. Single-incident traumas (a car accident, a one-time assault) often resolve in fewer sessions than complex or developmental trauma that spans years. Your therapist will give you a clearer picture after Phase 1 history-taking, once they understand the scope of what you’re working with. Treatment length also depends on how you respond to reprocessing, which varies from person to person.
Does EMDR work for anxiety and depression, or only PTSD?
EMDR was originally developed for PTSD, and that’s where the strongest research base sits. It’s also used for anxiety, phobias, grief, and other presentations where distressing memories or experiences are driving current symptoms. Whether it’s the right approach for your specific situation depends on a clinical assessment, not a general answer. If you have questions about whether your situation is a good fit, Wholetherapy’s FAQ covers this in more detail.
What does bilateral stimulation feel like during an EMDR session?
Most people describe it as mildly absorbing but not uncomfortable. Eye movements (following a light or the therapist’s fingers) are the most common form, but therapists also use alternating taps on the hands or knees, or headphones with tones that alternate between ears. You’re not hypnotized and you’re not unconscious. You’re aware of what’s happening the whole time, and you can stop at any point by raising your hand or saying so.
Can I do EMDR therapy online, or does it have to be in person?
EMDR can be delivered via telehealth, and many therapists adapted to this during the pandemic with good results. Online delivery requires some adjustments, particularly for bilateral stimulation, but trained therapists have workable solutions. Whether in-person or online is better for you depends on your specific situation, your comfort with technology, and what your therapist recommends after an initial assessment. If you’re in Nova Scotia and want to explore options, you can contact us to discuss what’s available.
What should I do if I feel worse after an EMDR session?
Feeling unsettled, emotional, or tired after a reprocessing session is common and doesn’t mean the therapy is harming you. Your therapist will prepare you for this possibility and give you stabilization tools to use between sessions. If you’re experiencing significant distress that your stabilization skills aren’t managing, contact your therapist directly. If you’re in crisis, please reach out to a crisis line or emergency services rather than waiting for your next appointment.
