What Is EMDR Therapy and How Does It Actually Work?

EMDR (Eye Movement Desensitization and Reprocessing) is a research-backed therapy that helps your brain finish processing memories that got "stuck" — the kind that still feel like they're happening now, even though they're long over. Using bilateral stimulation (guided eye movements, tapping, or sound), EMDR helps a painful memory move from feeling raw and reactive to feeling like something that simply happened.


That's the short answer. Here's what it actually looks like in practice.


Why memories get "stuck" in the first place

When something overwhelming happens, your brain doesn't always file it away the way it files an ordinary memory. Instead, it can stay lodged in a raw, unprocessed state — which is why a smell, a tone of voice, or a passing comment years later can trigger the same flood of feeling as the original moment. This isn't a flaw in you. It's what an overwhelmed nervous system does to survive something it couldn't fully process at the time.


How EMDR Therapy helps

During EMDR, you bring a specific memory to mind while engaging in bilateral stimulation — this could be guided eye movements, alternating taps, or sound. This back-and-forth stimulation appears to help the brain do the processing work it wasn't able to complete in the moment the memory was formed. Over a series of sessions, the memory typically loses its emotional charge. You still remember what happened — you just stop reliving it.


Not all EMDR looks the same

My approach is also Polyvagal-informed, meaning we don't move straight into reprocessing. We build nervous system safety first, and if any protective "parts" of you (see: Internal Family Systems Therapy) aren't ready to approach a memory, we work with that before we work with the memory itself. You can read the full clinical breakdown of this integrated approach on the EMDR Therapy page, or go deeper in the companion post, What Is EMDR Therapy? How It Works for Trauma, Anxiety & PTSD.


FAQ

Does EMDR require medication or hypnosis? No. EMDR doesn't involve medication or hypnosis — you remain fully aware and in control throughout each session.

Is EMDR only for "big T" trauma like accidents or abuse? No. EMDR is used for single-incident trauma as well as smaller, cumulative experiences — like chronic emotional neglect or years of people-pleasing — that still shape how you respond today.
