How EMDR Actually Works

A therapy room set up for an EMDR session

Most people who ask me about EMDR have already done a lot of work. They can explain what happened to them. They can tell you which parent it started with, and roughly what age. And their body still does what it does: braces at a tone of voice, floods at a look, goes blank in a conflict that is not actually dangerous.

That gap, between what you understand and what your body still believes, is the thing EMDR works on.

What a memory does when it never finished

Ordinary memories settle. They lose their charge, they move into the past tense, they stop feeling urgent. An overwhelming one can get stored before any of that happens: the images, the body sensations, and the conclusion you came to in that moment, all kept in their raw form, as if the thing has not been dealt with yet. Because it has not.

Which is why something small in the present can pull you back so fast. Something in the room matches the old file, and your body answers the old file rather than the room.

What actually happens in a session

EMDR stands for eye movement desensitization and reprocessing, which is a long name for a fairly simple structure. You make brief contact with a piece of a memory, not the whole story, while something engages both sides of your attention: eye movements, tapping, or alternating sound. Then we stop and notice what came up. Then we do it again.

What we are after is the processing your brain never got to finish. You are awake, you are in control, and you can stop at any point.

We also do not start there. The first sessions are about getting steady enough to do the work: understanding how your nervous system responds, and building something to come back to when it gets intense. Going straight at the worst memory without that usually just re-floods you, and teaches your body that therapy is one more place where it is not safe.

The eight phases, in plain language

The protocol has eight phases, and they are less mysterious than the list makes them sound. The first three are preparation: taking your history and deciding whether this is the right tool, teaching you how to settle yourself, and then picking the specific memory and the belief attached to it: I am not safe, it was my fault, I am too much.

The middle phases are the work itself: reprocessing the memory until it loses its charge, then strengthening the belief you would rather live from, then checking what your body is still holding. The last two are closure and reevaluation: ending each session settled rather than cracked open, and starting the next one by checking what actually moved.

What EMDR does not do

It does not erase the memory. You will still know what happened. What changes is how much of your present it gets to occupy.

It is not hypnosis. You are awake and aware the entire time, and you can stop.

It does not require you to narrate everything out loud. For anyone who has already told the story enough times to go numb saying it, that is usually the part that makes the work possible at all.

And it is not something to do to yourself at home. I want to be direct about that one, because the internet is full of it. Tapping along to a video while you think about the worst thing that ever happened to you is not EMDR. The protocol is built around someone watching what your nervous system is doing and stopping the process when you cannot hold it — that is not an accessory to the method, it is the method. Wanting to get at it faster, on your own, makes complete sense. It is also how people re-traumatize themselves.

What I actually use it for

The strongest evidence behind EMDR is for PTSD; it sits in the World Health Organization’s guidance for trauma-related conditions alongside trauma-focused CBT. In my practice it also gets used for the wounds that formed inside relationships: childhood neglect and attachment injuries, betrayal where the images will not stop replaying, grief that has gotten stuck rather than moved, panic that traces back to something specific.

It is rarely the whole plan. It usually sits inside broader trauma work or individual counseling, as the tool we reach for when talking has taken you as far as talking goes.

If your body already knows the story by heart

If you can explain the whole thing and still react the way you react, that is not a failure of insight. It is what an unprocessed memory does. EMDR therapy works on that gap directly, and we go at the pace your body can actually tolerate.

You do not have to retell the whole story to get somewhere with it.
