What Does EMDR Therapy Actually Look Like in a Session?

If you’ve heard about EMDR therapy but aren’t quite sure what actually happens during a session, you’re not alone. Descriptions of EMDR often focus on eye movements or “processing trauma,” which can make the experience sound mysterious or intimidating if you’ve never tried it.

Eye Movement Desensitization and Reprocessing (EMDR) is a structured form of psychotherapy originally developed to treat trauma and post-traumatic stress. Although bilateral stimulation is one recognizable part of the approach, EMDR involves much more than following something back and forth with your eyes.

EMDR therapy follows eight phases, including learning about your history and goals, preparing for processing, identifying experiences to work on, reprocessing those experiences, and evaluating how the work is affecting you over time. What a particular session looks like depends on where you are in that process.

What Happens During an EMDR Therapy Session?

Every EMDR session looks a little different depending on which phase of treatment you're in. Those phases provide a framework for treatment rather than a checklist that must be completed during every appointment.

These phases provide a framework for treatment rather than a checklist that must be completed during every appointment.

Your early sessions may look more like other forms of therapy than you expect. You and your therapist may discuss what brings you to therapy, relevant experiences from your history, current symptoms or triggers, and what you hope will change. Your therapist will also assess whether EMDR is appropriate for you and develop a treatment plan based on your individual needs.

Do You Start Processing Trauma Right Away in EMDR?

No. EMDR therapy includes preparation before reprocessing begins, and some people spend considerably more time in the preparation phases than others.

During preparation, your therapist will explain how EMDR works, answer questions, establish expectations, and help you develop strategies for managing distress that may arise during or between sessions. Building a trusting therapeutic relationship and determining whether you are ready to move into reprocessing are also important parts of the process.

This means you shouldn't expect to walk into your first EMDR appointment and immediately begin revisiting a painful experience. The pace of treatment depends on your history, current needs, ability to manage distress, and treatment goals.

What Happens When You Begin Reprocessing a Memory?

When reprocessing begins, you and your therapist identify a specific experience to target along with the thoughts, emotions, images, and physical sensations connected to it.

Your therapist may ask you to notice a negative belief associated with the experience, such as a belief about yourself or your safety, as well as a more adaptive belief you would prefer to hold. You may also be asked to rate how distressing the memory currently feels and how true the more adaptive belief feels to you.

During reprocessing, you briefly bring aspects of the target experience to mind while engaging in bilateral stimulation. Between sets, your therapist may ask you to notice what is coming up without trying to force the experience in a particular direction.

New thoughts, emotions, images, memories, or physical sensations may emerge as the process continues. Your therapist uses the structured EMDR protocol to guide the work while monitoring your experience throughout the session.

What Does Bilateral Stimulation Actually Feel Like?

Bilateral stimulation involves alternating stimulation from one side of the body to the other while you attend to aspects of the experience being processed.

Side-to-side eye movements are probably the best-known form, but they aren't the only option. EMDR therapists may also use alternating sounds or taps.

The experience can therefore look somewhat different depending on the method being used. Importantly, bilateral stimulation is one component of EMDR therapy rather than the treatment by itself. The history, preparation, assessment, reprocessing, closure, and reevaluation surrounding it are all part of the larger therapeutic approach.

Do You Have to Describe Your Trauma in Detail?

EMDR generally does not require you to give an extensive verbal account of a traumatic experience in the way people sometimes imagine trauma therapy will.

You will still need to communicate enough with your therapist to identify what you are working on and the thoughts, emotions, images, or physical sensations connected to it. However, EMDR can involve less detailed verbal recounting of a disturbing memory than some other forms of trauma-focused therapy.

For people who feel apprehensive about describing painful experiences in exhaustive detail, understanding this distinction may make EMDR feel more approachable. Your therapist can explain what information they need from you and what you can expect before reprocessing begins.

What Happens If You Feel Overwhelmed During EMDR?

You can communicate with your therapist and ask to stop reprocessing if you become overwhelmed or need a break.

Part of EMDR preparation involves developing strategies that can help you manage emotional distress, and maintaining a sense of client control is an important part of the process. Your therapist should also monitor your responses and help you remain connected to the present while difficult material is being processed.

EMDR sessions include a closure phase whether or not the targeted material has been completely processed. If processing is unfinished, the therapist helps you return to the present and regain emotional equilibrium before the session ends.

How Do You Know Whether EMDR Is Working?

EMDR includes ongoing reevaluation so you and your therapist can assess how previously targeted material is affecting you and determine what to work on next.

The goal isn't to erase a memory or pretend that a painful experience didn't happen. Instead, treatment is intended to reduce the distress associated with the experience and support more adaptive ways of relating to it.

Progress may involve changes in emotional distress, beliefs about yourself or the experience, physical responses, or reactions to current triggers. Because treatment is individualized, your therapist can help you evaluate what meaningful progress looks like in the context of your own goals.

How We Use EMDR Therapy at Insight

Insight Therapy NYC offers EMDR as one of several therapeutic approaches available to clients seeking support with trauma and other distressing life experiences.

Because EMDR is a structured psychotherapy rather than a single technique, treatment involves more than bilateral stimulation alone. An EMDR therapist considers your history, current concerns, treatment goals, and readiness for reprocessing when determining how to approach the work.

Your experience of EMDR may therefore look different from someone else's. Therapy should be responsive to your individual needs rather than forcing every client through treatment at the same pace.

If you're interested in EMDR but aren't sure whether it's the right approach for you, an initial consultation can give you an opportunity to ask questions and learn more about your options.

Not Sure If EMDR Is Right for You?

If you're curious about EMDR but still have questions about what the process would look like for you, you don't need to decide whether it's the right treatment before reaching out.

Frequently Asked Questions About EMDR Therapy 

• Is EMDR just eye movements?

  No. Eye movements are one possible form of bilateral stimulation used during portions of EMDR, but EMDR itself is a comprehensive eight-phase psychotherapy. Treatment also includes history taking, preparation, assessment, reprocessing, closure, and reevaluation.

• Will I have to talk about my trauma in detail during EMDR?

  Not necessarily. You will need to identify the experience you're working on and aspects of it that are relevant to treatment, but EMDR does not necessarily require an extensive verbal retelling of the traumatic event. Your therapist can explain what information will be needed before you begin processing.

• Does EMDR happen during the first session?

  The first session may be part of EMDR treatment, but reprocessing generally does not begin immediately. Early treatment includes history taking, treatment planning, preparation, and determining readiness for reprocessing. How much preparation someone needs varies from person to person.

• Can I stop during EMDR if I become uncomfortable?

  Yes. Clients remain in control during EMDR and can ask to stop or pause bilateral stimulation. Preparation and closure are also built into the treatment process to help clients manage distress and return their attention to the present.

• How many EMDR sessions will I need?

  There isn't one number that applies to everyone. The length of EMDR treatment depends on factors such as what you're seeking treatment for, your history, the number and complexity of experiences being addressed, and how you respond to treatment. Your therapist can give you a better sense of the expected course of treatment after learning more about your individual needs.
