If you’ve been researching therapy for trauma, you’ve likely come across the term EMDR. Maybe someone recommended it to you. Maybe your therapist mentioned it. Maybe you’ve watched a video or two and still aren’t entirely sure what’s actually happening in an EMDR session, or whether it could help you.
This post is for you. I want to break down what EMDR actually is, what it feels like from the inside, and why it’s become one of the most well-researched and widely used approaches in trauma treatment today.
What Is EMDR?
EMDR stands for Eye Movement Desensitization and Reprocessing. It was developed in the late 1980s by psychologist Francine Shapiro, who noticed that certain eye movements seemed to reduce the intensity of distressing thoughts.
Since then, it has been extensively researched and is now recommended by organizations including the World Health Organization (WHO) and the American Psychological Association as an effective treatment for PTSD and trauma-related difficulties.
But here’s what EMDR is, at its heart: it’s a way of helping the brain finish processing something it got stuck on.
Why Does the Brain Get “Stuck”?
When we experience something overwhelming, something our nervous system couldn’t fully process at the time, the memory doesn’t get stored in the same way ordinary memories do. Instead of being filed away as a past event, it stays “live.” Triggered easily. Felt in the body. Present-tense, even when it isn’t.
This is why trauma survivors often describe their symptoms not as remembering something, but as reliving it. The past is happening now, in the body, in the nervous system.
EMDR works by activating that stuck memory while simultaneously engaging the brain’s natural processing system, allowing the memory to be reprocessed, integrated, and finally filed as past.
What Actually Happens in a Session?
EMDR is done in phases, and a responsible EMDR therapist won’t rush this. The first several sessions are about building safety, developing coping skills, establishing trust, and identifying what we’re going to work on.
When processing begins, you’ll be asked to hold a difficult memory in mind, along with the emotions, body sensations, and negative beliefs associated with it, while engaging in bilateral stimulation. This is usually eye movements (following the therapist’s fingers or a light bar), but it can also be tapping or auditory tones that alternate between sides.
Then you simply notice what comes up. Thoughts, images, sensations, emotions. You don’t have to analyze them or talk about them in detail, you just let the processing happen. The therapist guides you through sets of bilateral stimulation, checking in periodically, until the memory’s charge is significantly reduced.
Most people describe the experience as strange but not as hard as they expected. The memory becomes less vivid, less emotionally loaded. The negative beliefs about themselves that were attached to it begin to shift.
What Kinds of Trauma Can EMDR Help?
EMDR is often associated with single-incident trauma, a car accident, assault, or medical event, and it works powerfully for these. But its applications are much broader.
Complex / Childhood Trauma
EMDR can be adapted for complex trauma, including the relational wounds of childhood neglect, emotional abuse, or growing up with an emotionally immature or narcissistic parent. This typically requires more preparation and a slower pace, but many people find it deeply transformative.
Narcissistic Abuse
The specific memories, moments of humiliation, and core beliefs created by narcissistic abuse can be targeted and processed with EMDR, helping survivors shift from “I’m not enough / I’m too much” to something more grounded and true.
Perinatal Trauma
Birth trauma, traumatic pregnancy losses, and experiences in the perinatal period that were frightening or overwhelming can also be effectively addressed with EMDR.
Anxiety
Many anxiety presentations have roots in earlier experiences. EMDR can help identify and process those roots, reducing anxiety that hasn’t responded well to cognitive approaches alone.
Is EMDR Right for Everyone?
EMDR is a powerful tool, and like any powerful tool, it needs to be used thoughtfully. It’s not appropriate to begin trauma processing before sufficient stabilization and safety have been established. A well-trained EMDR therapist will take the time to prepare you thoroughly before any processing begins.
It’s also worth knowing that EMDR can bring up difficult emotions and memories during and between sessions. This is normal, it means processing is happening. But it’s important to have support around it.
A Final Word
People are sometimes skeptical of EMDR, the eye movement component can seem unusual, even a little “out there.” That’s understandable. But the research is robust, and the lived experience of those who’ve done it often speaks for itself.
You don’t have to relive everything in graphic detail. You don’t have to talk your way through every painful memory. Sometimes healing looks like following a light bar and noticing, slowly, that the thing that once felt unsurvivable is beginning, finally, to feel like the past.
