What is EMDR Therapy? A Beginner's Guide to How It Works

Are you randomly Googling, “What is EMDR therapy?” Did someone recommend it to you? Did you hear those four letters and think, What in the world is that? Maybe you watched a few videos and thought, This looks like some weird voodoo stuff.

If so, you are not alone. EMDR can sound a little unusual when you first hear about it. So, what exactly is it?

What Is EMDR?

EMDR stands for Eye Movement Desensitization and Reprocessing. It was developed in the late 1980s and has become a widely used, evidence-based treatment for trauma and PTSD. EMDR may also be helpful for concerns such as anxiety, phobias, grief, childhood trauma, depression, and distress related to experiences such as car accidents.

I like to explain EMDR to my clients using a metaphor.

Imagine that your brain is a large, messy room filled with clothes, papers, dust, and all the little things you collect throughout the day. The room represents your daily life and the thoughts, emotions, and experiences your brain takes in.

Luckily, you have your own personal maid who works the night shift.

While you sleep, your maid clocks in and begins organizing the room. She folds the clothes and puts them into drawers. She sweeps the floor, dusts the furniture, throws away the trash, and places everything where it belongs.

Most nights, this system works pretty well.

Then, one night, your maid comes across a piece of trash she has never seen before. Usually, she knows exactly where everything belongs and how it should be filed away. However, this particular piece is unfamiliar, overwhelming, and difficult to sort.

She does the best she can, completes the rest of her routine, and leaves that piece sitting in the middle of the room.

The next night, she comes back and notices that it is still there. Except now, there is more trash surrounding it.

Our brains naturally connect experiences that feel similar. A sound, smell, situation, relationship, or emotion may remind the brain of that original experience, so it gets added to the same pile. Day by day, the pile becomes larger.

Eventually, your maid becomes overwhelmed because she still does not know what to do with it.

That pile may begin shaping how you feel about yourself, how you view other people, and how safe you believe the world is. It may contribute to beliefs such as:

I am not safe.

I am not good enough.

I cannot trust anyone.

Something bad is going to happen.

The important thing to remember is that nothing is wrong with your maid. She is not broken. She simply encountered something so overwhelming that she did not know how to properly sort and store it.

She needs some extra support going back into the room, sorting through the pile, and putting those experiences where they belong so they are no longer taking up so much space.

That is where EMDR comes in.

Through bilateral stimulation, also called BLS, EMDR uses alternating left-and-right stimulation through eye movements, tapping, or sounds. In simple terms: left, right, left, right.

This process helps support your brain’s natural ability to work through distressing experiences so they can feel more connected to the past rather than continuing to feel active in the present.

What Happens During an EMDR Session?

I know it can feel really vulnerable to walk into a therapy office and feel like you’re supposed to already have everything figured out. If that’s where you are, I just want to gently say—take a deep breath. You don’t have to rush yourself here.

A good EMDR therapist will not expect you to come in on day one and immediately start processing your most painful memories.

You are not expected to walk in and dive straight into trauma work.

EMDR is divided into eight phases designed to help you feel informed, prepared, and supported throughout the process.

1. History Taking

During this phase, your therapist learns more about you, your background, your current concerns, and what you hope to gain from therapy.

2. Preparation

This phase focuses on helping you feel emotionally prepared for trauma work. It may include building coping skills, practicing grounding techniques, strengthening supportive resources, and increasing your confidence in managing difficult emotions.

In my practice, preparation may also include learning more about the protective parts of yourself and understanding how they have helped you survive.

3. Assessment

Together, you and your therapist identify the memory or experience you would like to work on. You will also explore the thoughts, emotions, and body sensations connected to it.

4. Desensitization

This is the phase most people think of when they hear about EMDR. During this phase, you begin actively processing the memory while using bilateral stimulation.

5. Installation

Once the distress connected to the memory begins to decrease, you work on strengthening a healthier and more helpful belief about yourself.

For example, a belief such as I am powerless may begin shifting toward I have choices now or I survived and I am safe in the present.

6. Body Scan

Your therapist will invite you to notice whether there is any remaining tension, discomfort, or distress in your body connected to the memory. Sometimes our minds feel calmer while our bodies are still holding on to part of the experience.

7. Closure

The session ends with grounding, reflection, and making sure you feel stable before leaving. You and your therapist may also discuss what you noticed and what to expect between sessions.

8. Re-evaluation

At the beginning of a future session, your therapist will check in about how the memory feels now, whether anything new has come up, and what the next step should be.

Every phase has a purpose. There is no gold medal for moving through them quickly. Therapy is not a trauma-processing speed

run.

Do I Have to Talk About Every Detail?

The good news is no.

EMDR does not require you to share every painful or uncomfortable detail of what happened. You get to choose how much you want to disclose, and you remain in control throughout the process.

Your therapist may need enough information to understand what you are working on and support you safely, but you do not have to describe every moment of the experience.

My role is not to force you to relive what happened. My role is to help you process it in a way that feels safe, supported, and manageable.

My Approach to EMDR

As an EMDR Certified therapist, I do not believe healing comes from rushing into trauma processing.

I spend time helping clients build coping skills, strengthen their support systems, and feel prepared before beginning reprocessing. I may also integrate concepts from Internal Family Systems, or IFS, to help clients better understand the protective parts of themselves that may feel anxious, hesitant, or unsure about trauma work.

My goal is to help clients move at a pace that feels safe while working toward meaningful and lasting change.

Final Thoughts

Healing from trauma does not mean forgetting what happened. It means the memories no longer have the same power over your present.

EMDR is one evidence-based approach that may help people process painful experiences, reduce emotional distress, and move forward with greater confidence, flexibility, and peace.

If you are wondering whether EMDR might be a good fit for you, scheduling a consultation can give you an opportunity to ask questions, learn more about the process, and decide whether the therapist’s approach feels right for your needs.
