What Does an EMDR Session Actually Feel Like?
Most people find EMDR less complex than they expected.
You sit in a chair, fully awake, following a moving light or a set of alternating taps while holding a memory in mind. You talk considerably less than in regular therapy. And you usually leave tired in a way that's hard to describe.
But that’s just the short version. And you probably still have questions. So, here's the longer one, because I think the uncertainty is what stops most people from trying it.
Why nobody can picture it
The concept of traditional talk therapy is wildly understood before you walk in. You talk, someone listens, you talk more. While the process might feel abstract, the format seems normal enough.
EMDR isn't like that. People arrive having heard it "rewires your brain" or "works without talking about it," which sounds either miraculous or slightly suspect depending on your temperament. Neither description tells you what you'll actually be doing when you walk into your very first session.
So let me tell you what you'll actually be doing!
You won't start with EMDR
This surprises people, and it's the part I most want you to know before you book.
We don't reprocess anything in your first session. Usually not even your second!
The first phase of our work is history. As your therapist, I need to understand what you're carrying, how long, what you've already tried, what your life can absorb right now. Then preparation, where together we build what we call your resources: ways to settle your nervous system that work reliably, so that when we open something difficult, you know you can handle it.
I know this can feel like a delay when you've finally decided to do something. I promise, this phase holds just as much significance as the reprocessing itself. The preparation is what makes the rest safe, and skipping it is how EMDR goes badly.
For most people that's one to three sessions. Sometimes more, particularly with complex or childhood trauma, where there's more to stabilize before we go anywhere near the material.
Setting up a target
When we're ready, we choose a target — one specific memory, not your whole history. I'll ask you a few questions about it. What image comes to mind when you think of that moment? What does it make you believe about yourself? Something like I'm not safe, or it was my fault, or I'm not enough — usually a belief you can argue with intellectually and still feel in your chest.
Then: what would you rather believe? And where do you notice this in your body right now?
I'll ask you to rate the distress from zero to ten. We use that number to track whether anything's shifting, which matters because change during EMDR is often gradual enough that you'd miss it otherwise.
This part takes ten or fifteen minutes and it feels like ordinary therapy. You're just talking.
The reprocessing itself
Then we start the bilateral stimulation.
That might be following my fingers or a light bar with your eyes. It might be tapping — alternating left and right, either me tapping your hands or you tapping your own knees. It might be tones alternating between your ears through headphones. They're about equally effective, so we use whichever suits you. Plenty of people find the eye movements uncomfortable and switch to tapping.
I'll ask you to bring up the image and the belief, and then to follow the stimulation.
We go for maybe thirty seconds. Then I stop and ask: “what do you notice?”
You say whatever's there. It might be a thought, an image, a physical sensation, a completely unrelated memory, or nothing at all. All of those are fine — genuinely! There's no right answer, and I'm not evaluating what comes.
Then I say “go with that”, and we do it again. And again. And again.
That's the whole rhythm! Sets of stimulation, a brief check-in, another set. For most of the session I'm saying very little, and you’re saying whatever comes up (even if it doesn’t make sense).
What it feels like from the inside
People describe it in fairly consistent ways.
Your mind wanders and that's the point. You start on one memory and find yourself somewhere adjacent — a different year, a different person, something you hadn't thought about in a decade. That's usually the work happening, not you losing focus. You’re meant to let your brain lead you wherever it decides to go.
Emotion arrives faster than you'd expect. Not always! But it's common to feel something rise suddenly and then, a set or two later, subside. Riding that wave with someone you trust in the room is a large part of why it works.
Your body participates. Tightness, heat, nausea, shaking, tears, or a sudden heaviness in your arms. Trauma is stored physically, and the physical is often where the shift is most noticeable.
Then it flattens out. The most common thing people say near the end is a version of: I can think about it now, but it feels further away. The memory hasn't gone anywhere, but the “charge” it holds can change.
What it isn't
It isn't hypnosis. You're awake and in control the entire time. You can stop whenever you want, and I'll respect you when you say stop.
You don't have to describe what happened. This is EMDR's real advantage and the thing people are most relieved to hear. I need enough to identify a target, not a full account. Plenty of my clients have processed memories they've never said out loud to anyone.
You won't relive it. The whole design of EMDR keeps one foot safely in the present — that's what the bilateral stimulation is doing! You're observing the memory, not re-entering it.
How the session ends
Every session closes deliberately. We don't stop mid-wave.
If we've finished the target, we check where the distress sits now and spend time on the belief you'd rather hold. If we haven't finished — which is very normal — we do some regulation work together, so you can re-enter your day.
Important to note: processing often continues afterward. You may dream more vividly, or notice things surfacing over the next few days. That's expected. It's also why I'd suggest not scheduling something demanding immediately after your first few sessions.
Most people feel tired. Some feel unexpectedly light. Both are normal, and there is no right or wrong.
How many sessions
For a single-incident trauma — one event you’d like to work on — often six to twelve reprocessing sessions create change. For complex or developmental trauma, longer. Months rather than weeks, because there's more material and more resourcing to build. For many of my clients who also struggle with eating disorders, the timeline tends to be longer due to the complexity of both ED and trauma. I can always give you a real estimate after the history-taking as this will vary case by case (and can change based on what we discover together during reprocessing).
