EMDR therapy feels unlike traditional talk therapy. Instead of spending most of your time narrating painful events out loud, you briefly focus on a traumatic memory while your therapist guides your eyes back and forth, plays alternating tones, or uses gentle taps. Sessions typically last 50 to 90 minutes, and a full course of treatment averages 6 to 12 sessions, delivered once or twice per week.
What Happens Before the Eye Movements Start
EMDR follows an eight-phase protocol, and the eye movements don’t begin right away. The first few sessions are spent on history, relationship building, and preparation. Your therapist will ask about what brought you in, discuss which memories to target, and teach you specific techniques for calming yourself if strong emotions come up during or between sessions. This groundwork matters because the later phases can bring up intense feelings, and you need tools ready before that happens.
Once you and your therapist agree on a target memory, you’ll identify the image that represents the worst part of it, the negative belief you hold about yourself because of it (something like “I’m not safe” or “It was my fault”), and the emotions and body sensations that show up when you think about it. You’ll also rate how disturbing the memory feels on a 0-to-10 scale. That number becomes the baseline your therapist uses to track progress.
What the Reprocessing Phase Actually Feels Like
The core of EMDR, and the part most people are curious about, is called desensitization. Your therapist asks you to hold the target memory in mind while following a moving stimulus with your eyes. This is often the therapist’s fingers moving side to side, a light bar, or a dot on a screen. Some therapists use alternating sounds through headphones or gentle taps on your hands or knees instead. Each set of eye movements lasts roughly 30 seconds.
Between each set, your therapist pauses and asks what came up. You might notice a shift in the image, a new memory surfacing, a change in emotion, or a physical sensation like tightness in your chest loosening. You don’t need to narrate the full story. A brief description is enough, and then the next set begins. The process often feels like watching a train go by: you observe the thoughts and sensations moving through without having to control them.
Emotionally, the experience varies widely. Some people feel a wave of sadness, anger, or fear that peaks and then subsides within minutes. Others notice the memory becoming more distant or blurry, almost like watching it on a screen rather than reliving it. Physical reactions are common too. People report feeling heat, tingling, nausea, heaviness, or sudden relaxation as the memory shifts. These sensations are temporary and typically pass within the session. The goal is to keep going until the disturbance rating drops to zero or near zero, at which point most people describe the memory as something that happened but no longer carries an emotional charge.
How It Differs From Talk Therapy
In traditional talk therapy, you spend a lot of time describing what happened and analyzing how it affected you. EMDR is less verbal. You revisit the memory internally, but the therapist isn’t asking you to recount every detail or interpret its meaning. The bilateral stimulation, the side-to-side eye movements or tapping, appears to help the brain reprocess the memory in a way that resembles what happens during REM sleep. Brain imaging studies show that the eye movements reduce activity in the areas responsible for emotional threat responses, which helps explain why a memory that once triggered panic can start to feel neutral.
This also means EMDR tends to move faster than many people expect. Research has found that 84 to 90 percent of people with a single traumatic event no longer met the criteria for PTSD after just three 90-minute sessions. For people carrying multiple traumas, about 77 percent lost their PTSD diagnosis after six sessions. Combat veterans, whose trauma is often more layered, showed similar results after 12 sessions.
What to Expect After a Session
EMDR doesn’t stop working when the session ends. Your brain continues processing the targeted memory in the hours and days that follow, and this can show up in noticeable ways. Vivid or unusually detailed dreams are one of the most commonly reported effects. You may also feel more emotionally sensitive than usual, reacting more strongly to conversations or situations that wouldn’t normally bother you. Some people feel mentally drained or lightheaded immediately after a session because of the intense focus involved.
It’s also possible for new memories or feelings to surface between sessions, ones you hadn’t anticipated. A distressing memory connected to the one you targeted might emerge on its own. This is a normal part of the process and something your therapist will check on at the start of the next session during what’s called the reevaluation phase. If the original memory still feels neutral and the positive belief you’re building feels strong, you move on to the next target. If something still feels unresolved, you return to it.
Virtual EMDR Sessions
EMDR is increasingly offered through telehealth, and the experience translates well to a screen. Therapists use tools like a virtual light bar attached to their webcam, alternating audio tones through your headphones, or wearable devices that deliver gentle vibrations to each hand. A study of 288 patients found no significant differences in outcomes between virtual and in-person EMDR, making remote sessions a practical option if you don’t have a certified therapist nearby.
Finding a Qualified Therapist
EMDR requires specialized training beyond a standard therapy license. A therapist certified through the EMDR International Association (EMDRIA) has completed an approved basic training program, conducted at least 50 EMDR sessions with a minimum of 25 clients, received 20 hours of consultation from an approved consultant, and completed 12 hours of continuing education specific to EMDR. They must also have at least two years of experience in their licensed field. Asking whether a therapist is EMDRIA-certified is the simplest way to verify their qualifications. Therapists who have completed basic EMDR training but haven’t yet reached certification can still practice EMDR, but certified therapists have logged significantly more supervised clinical hours with the method.
