What is EMDR, and how does it help trauma?
What actually happens in EMDR, and why it works
EMDR sounds strange before you've tried it. Eye movements, taps, a memory from years ago you're supposed to think about on purpose. It's a reasonable thing to be skeptical of. Most people who ask me about it start from some version of "is this actually evidence backed, or is this just something people say works?"
It's a fair question, and it has a real answer. EMDR, Eye Movement Desensitization and Reprocessing, is one of the most researched treatments for trauma that exists. It's not a wellness trend. It's a structured, phase-based therapy with decades of outcome data behind it, and understanding what it's actually doing makes it a lot less strange.
Why memories get stuck
Most memories get filed away over time. You remember them, but they don't run the show anymore. Traumatic memories, especially ones from childhood or ones that happened repeatedly, often don't get that same filing treatment. Instead they stay reactive, half-processed, sitting closer to the surface than an ordinary memory should.
That's why a smell, a tone of voice, or a certain kind of silence can put you right back in something that happened years ago, in your body, not just your thoughts. The memory isn't the problem exactly. It's that your nervous system never got to finish processing it the way it processes most things.
What actually happens in a session
EMDR follows a structured sequence, not a free-associative conversation about your past. It generally moves through a few distinct phases.
Preparation
Before we touch anything traumatic, we build safety and a felt sense of stability. This isn't a formality. If your system isn't ready, none of the rest of this works.
Target selection
We identify one specific memory or belief to work with, not your entire history at once. Trying to process everything simultaneously isn't how this works, and it isn't the goal.
Processing
With bilateral stimulation, guided eye movements, taps, or alternating sounds, we move through the memory in structured sets, checking in throughout. You keep one foot in the memory and one foot in the present moment. This is called dual awareness, and it's the whole point. You're not reliving the event. You're revisiting it with enough present-moment grounding that your brain can finally finish what it started.
Closure
Every session ends with grounding, regardless of where we land in the memory. You don't leave activated. You leave regulated.
What shifting actually looks like
I've watched this happen directly with clients working through the shock of something that happened to them. What changes isn't the facts of the memory. It's the charge. The emotional intensity that used to come with it gets noticeably less, sometimes within a single session. Clients describe real somatic releases, tension actually leaving the body, not just calming down mentally but physically letting go of something they'd been holding for a long time. Negative beliefs that had been attached to the memory, things like "I'm not safe" or "it was my fault," often loosen or fall away entirely, without us having to argue the client out of believing them.
That's the part that surprises people most. You're not talked out of a belief. It just stops being true for you, once the memory underneath it isn't stuck anymore.
This usually isn't a one-session fix, and I try to set that expectation honestly up front. A single memory typically takes somewhere around six to eight sessions to fully process, sometimes fewer, sometimes more, depending on how much is attached to it. That number can feel discouraging if you're picturing one dramatic breakthrough. In practice, it's closer to a series of smaller shifts that build on each other, each one loosening the memory's grip a little further, until one day it's just a thing that happened instead of something running quietly in the background of your life.
Is this actually evidence backed
Yes. EMDR has been studied extensively and is recognized as an effective, evidence-based treatment for PTSD by major health organizations. The bilateral stimulation appears to help the brain access and reprocess stuck material in a way that resembles what happens naturally during REM sleep, when the brain does a lot of its ordinary memory processing. Nobody fully agrees on every detail of the underlying mechanism, but the outcomes themselves are well documented, not anecdotal.
What it isn't is a way of pretending something didn't happen, or erasing a memory. You'll still remember what happened. It just stops running the show underneath everything else.
Where I start instead, for complex trauma
Jumping straight into memory work can overwhelm a nervous system that isn't ready for it, especially with complex or repeated trauma. That's why I typically start with Internal Family Systems, building internal safety and a steadier relationship with the parts of you still holding old pain, before introducing EMDR at all. By the time we get there, your system usually has more actual capacity to integrate what comes up, instead of just tolerating it.
This pairing tends to matter most for complex PTSD and childhood emotional neglect, where the trauma isn't one incident but an accumulation, and the nervous system needs more groundwork before memory processing can actually hold.
Who this isn't the right fit for, yet
EMDR isn't the right starting point for everyone, and being honest about that matters more than pretending it works for everyone immediately.
- If you're in active crisis right now, EMDR isn't where we'd begin.
- If you're managing a dissociative disorder, this work needs a different kind of pacing and preparation before memory processing is safe.
- If what you're carrying is more attachment trauma, something relational and ongoing rather than a specific incident, we usually need to build a lot more stability first.
None of that means EMDR is off the table. It just means the order matters, and rushing it doesn't serve you. Part of my job in that first conversation is figuring out, honestly, whether we're ready to start there or whether we need to build more ground first.
Frequently asked questions
Does EMDR require talking about the trauma in detail?
No. You bring the memory to mind, but the processing itself happens largely through the bilateral stimulation, not through narrating every detail out loud.
Is EMDR only for one-time, major trauma?
No. It's effective for both a single overwhelming event and the cumulative, repeated experiences common in childhood emotional neglect or complex PTSD.
How many sessions does this actually take?
It depends on what we're working with. A single, specific memory can shift in a handful of sessions, often around six to eight. Complex or repeated trauma usually takes longer, partly because we spend real time on preparation and stabilization before processing even begins.
Will I feel worse before I feel better?
Sometimes, briefly, within a session, since you're actually engaging with material you've likely avoided for a long time. That's part of why preparation matters so much before we start, and why every session ends with grounding regardless of where the processing lands. You're not left activated between sessions.
