__________________________________________________________________________________

One of the most important parts of preparing a client for EMDR is helping them understand what we are asking their brain to do and what we are not asking them to do. Clients may come into EMDR expecting something mysterious, frightening, or even magical. Some believe they will have to relive every detail of their trauma. Others expect one session to erase a painful memory completely. Good psychoeducation can reduce that fear and create realistic expectations before reprocessing begins.

The following script is designed as a framework rather than something that must be memorized word-for-word. Clinicians should adapt the language to their own personality, the client's developmental level, and the client's understanding of trauma.

THE BASIC EMDR EXPLANATION

What I might say to a client:

“Before we start EMDR, I want to explain a little about what we're doing and why.

Your brain is constantly taking in information and trying to make sense of your experiences. Most experiences eventually get filed away as something that happened in the past. You can remember them, but you don't necessarily feel like you're back inside the experience every time you think about them.

Think about a childhood birthday. You may remember opening a present you were really excited about. You know you were happy. You may remember what the room looked like or who was there. But you're probably not experiencing exactly the same excitement in your body right now that you experienced when you were eight years old opening that present. The memory is still there. But it feels like a memory.

Trauma can be different. Sometimes an experience is so overwhelming that our normal information-processing system doesn't seem to fully integrate the experience.

Instead of feeling completely like something that happened in the past, parts of that experience can continue to feel present. That's why a reminder of something that happened years ago can suddenly cause your heart to race, your stomach to drop, your body to tense, or emotions like fear, shame, anger, or helplessness to come rushing back.

Intellectually, you may know: 'I'm safe now.' But another part of your brain and body is responding: 'This is happening again.'

EMDR is designed to help your brain process that experience so it can become more fully connected to the past. We can't erase what happened. We are trying to help your brain recognize: It happened. It mattered. And it isn't happening right now.”

EXPLAINING BILATERAL STIMULATION

Clients frequently want to know: “Why are we moving my eyes back and forth?” A simple explanation is often more useful than an overly technical one.

Client Script:

“One of the things you'll notice about EMDR is that we'll use something called bilateral stimulation. 'Bilateral' simply means we're alternating between the two sides. That might involve following something with your eyes from side to side, alternating sounds, tapping, or another form of left-right stimulation.

During that process, I'm going to ask you to notice what happens. You don't have to force anything. You don't have to figure out the 'right' thing to think about. And you don't need to make anything happen. Your job is mostly to notice.

Think of me as helping create the conditions for processing, while your brain does the actual work.”

A clinician note about explaining REM sleep

You may also hear EMDR explained through comparisons with the rapid eye movements that occur during REM sleep. That analogy can be useful for clients, but it is better presented as a helpful conceptual comparison rather than a settled explanation of exactly how EMDR works.

You might say:

“Researchers are still studying exactly why EMDR works. One theory involves some of the same kinds of information-processing processes associated with memory and sleep. The important part for you is that you don't have to consciously make the processing happen. We're creating conditions that help your brain work with the memory differently.”

This keeps the explanation accessible without presenting one proposed mechanism as established neuroscience.

THE SPLINTER METAPHOR

This is one of my favorite ways to explain trauma processing because almost everyone understands it immediately.

Client Script:

“Think about getting a splinter in your skin. Your body already knows how to heal a wound.

You don't sit there consciously telling your cells what to do next. Your body has a healing system. But if there's a splinter stuck inside the wound, healing becomes harder. The area stays irritated. It may become inflamed. Every time something touches it, it hurts. The problem isn't that your body doesn't know how to heal. There's something interfering with the healing process. Trauma can sometimes work similarly.

Your brain and nervous system have an incredible ability to adapt, process information, and heal. But sometimes an experience gets stuck in a way that keeps activating the system. EMDR isn't me healing your brain for you. Think of it more like we're helping remove what's interfering with the processing so your own system can do what it already knows how to do.”

This metaphor of the splinter represents trauma interfering with the body's natural healing process, while EMDR helps the system resume processing.

“YOUR BRAIN ALREADY KNOWS THIS”

Clients sometimes become frightened that EMDR is going to uncover something they cannot handle. I want to address that fear before we begin reprocessing.

Client Script:

“One thing I want you to remember is that we're not putting something into your brain that isn't already there. These memories, emotions, sensations, and experiences already exist within your system. You're already carrying them. What we're doing is creating a structured way to notice and work with information that may normally stay outside your awareness or show up indirectly through triggers, emotions, body sensations, nightmares, avoidance, or patterns. And we're going to do that together.

You aren't expected to know where the process is going. That's my job to help monitor what's happening, help you stay connected to the present, and adjust what we're doing when needed.”

It's important to help clients regain trust in themselves and their bodies because trauma frequently disrupts that trust. The information being processed in EMDR therapy already exists and that therapy simply is just helping to bring it into conscious awareness where it can be worked with.

THE TRAIN METAPHOR

One of the most common difficulties new EMDR clients experience is trying too hard. They start analyzing:

“Am I doing this correctly?”

“Was I supposed to think about that?”

“Why did that memory come up?”

“Should I go back to the original memory?”

“What does this mean?”

This can pull the client out of noticing and into intellectualizing the experience.

That's where the train metaphor can help.

Client Script:

“Imagine you're sitting beside a railroad track watching trains go by. Your thoughts, memories, emotions, images, and sensations are the train cars. You don't have to climb onto every train. You don't have to stop the train. You don't have to figure out where it's going. Just notice what passes by.

If suddenly you're thinking about something that seems completely unrelated, don't decide that you're doing EMDR wrong. Just notice it. Your brain may make connections that don't immediately make logical sense to you. Let it happen.

When we pause, I'll ask you what you noticed. You don't need to give me a perfect explanation. Just tell me what came up.”

This “watch the train go by” approach is typically discussed in your EMDR Basic Training specifically as a way of helping clients who become stuck in processing loops. Front-loading this information is important because more psychoeducation can make processing easier.

THE MOVIE METAPHOR

Some clients connect more easily with a movie metaphor.

Client Script:

“You can also imagine that you're watching a movie. You aren't directing the movie.

You aren't rewriting the script while you're watching it. You're simply noticing what appears on the screen. Something may show up that surprises you. A scene may change.

A memory may connect with another memory. An emotion may shift.

You may suddenly notice something in your body. That's okay.

Just notice what's happening and report back to me when we stop.”

This metaphor is another typically taught in EMDR Basic Training, which is teaching clients to watch processing unfold “like a train or a movie” rather than trying to control where their thoughts go.

EXPLAINING DUAL AWARENESS

A client needs enough connection with the memory for processing to occur while also maintaining awareness that they are currently safe in the therapy room.

I explain this as having, which I learned from my EMDR Basic Training through HAP and from my EMDR consultant for EMDR Basic Training and Certification:

One foot in the past and one foot in the present.

Client Script:

“There's a balance we're looking for during EMDR. I want you connected enough to the memory that your brain can work with it. But I don't want you so far inside the memory that you lose awareness that you're sitting here with me right now. Think about having one foot in the memory and one foot here in the room. Part of you notices what happened then. Another part of you knows:

I'm here.

I'm safe right now.

I'm sitting in this room.

I'm working with my therapist.

That's called dual awareness. If you start feeling too far away, disconnected, or completely pulled into the experience, tell me. And if you're so far outside of the memory that you're avoiding it entirely, we'll notice that too. We're looking for the middle.”

Ideally, with EMDR, you will want the client to understand it's important to neither become completely absorbed or dissociated nor become so externally focused that the person avoids the internal experience.

THE “BACK OF THE HEAD” SCALE

I sometimes give clients a simple physical reference point for dual awareness.

Client Script:

“Imagine a line running from the back of your head out toward the room. If you're way back here” (gesture toward the back of the head) “you're completely inside your head or disconnected from what's happening around you.

If you're way out here” (gesture outward) “you're completely focused on the room and may not really be engaging with the memory.

We're looking for somewhere in between. (gesture directly in line with the eyes) You can access what's happening internally while still knowing you're here with me.

During processing, I might ask:

'Where are you on the back-of-the-head scale?'

I'm just checking how connected you are to both experiences.”

This language closely reflects how to provide psychoeducation and introduce the tool of dual-awareness within the EMDR session.

“THERE IS NO RIGHT ANSWER”

This may be one of the most important things to tell a client.

Client Script:

“You cannot get an A in EMDR. There isn't a correct memory you're supposed to think about. You don't need to impress me. You don't need to figure out what I'm expecting you to say. And you don't have to make your experience make sense.

If I ask: 'What are you noticing now?' your answer might be:

'A memory.'

'A tight feeling in my chest.'

'Anger.'

'A color.'

'Nothing.'

'I suddenly thought about my grandmother.'

'I don't know.'

All of those give us information. Your job isn't to perform EMDR correctly.

Your job is to notice.”

This can be particularly important for highly cognitive or “heady” clients who already understand their patterns intellectually but have difficulty connecting that understanding to emotional and physical experiences.

EMDR IS NOT ABOUT GETTING RID OF EMOTIONS

Clients sometimes believe successful trauma treatment means they should eventually feel nothing. That isn't the goal.

Client Script:

“The goal of EMDR isn't to turn off your emotions. Your emotions serve a purpose. Fear can alert us to danger. Anger can tell us that something is wrong or a boundary has been crossed. Sadness tells us something mattered. We aren't trying to make you stop feeling.

We're trying to help your emotional system respond to what's happening now, rather than repeatedly responding to something that happened in the past.

The goal isn't: 'Nothing will ever bother me again.' It's closer to: 'When something bothers me, I can recognize what's happening, trust myself, and respond from the present.'”

This reflects the concept that emotions themselves are not the problem and that the therapeutic goal is learning to work with the emotional world rather than being at odds with it.

SETTING REALISTIC EXPECTATIONS

EMDR isn't magic. And promising that a client will never experience a particular emotion or negative belief again can actually undermine treatment.

Client Script:

“EMDR doesn't mean you'll never feel insecure, afraid, angry, ashamed, or triggered again. Life is still going to happen. What we're trying to change is your ability to recognize what's happening and access a more adaptive response. Instead of automatically believing: 'I'm not good enough.' you may eventually be able to notice:

'There it is. That's that old belief again. I understand why this situation activated it, but I don't have to treat it as the truth.'

That's a very different relationship with the thought.”

For complex trauma: complete elimination of negative cognitions may be unrealistic, while recognizing them, grounding, and responding differently represents meaningful progress.

THE 60-SECOND VERSION

Sometimes you don't need the entire explanation.

Quick Client Script:

“EMDR is based on the idea that your brain naturally tries to process experiences, but overwhelming experiences can sometimes remain connected to the emotions, beliefs, and body sensations you experienced when they happened. That's why something that happened years ago can still feel very present when you're triggered. During EMDR, we'll use bilateral stimulation, such as eye movements, sounds, or tapping, while you briefly notice parts of the experience. You don't have to force anything or figure out what you're supposed to think. Imagine watching your thoughts and memories go by like train cars.

Your job is to notice. My job is to help guide the process and make sure you stay connected enough to the memory to work with it while also knowing that you're safe here in the present. We're not trying to erase your memory. We're helping your brain recognize: That happened then. I'm here now.”

THE CLINICIAN'S MINDSET

The explanation itself matters, but how confidently you deliver it matters too. If you're visibly anxious about EMDR, clients (particularly trauma survivors who have learned to closely monitor other people's emotional states) may detect that uncertainty. You do not need to know exactly where processing will go. You do need to understand the protocol well enough to confidently communicate:

I know what we're doing.

You don't have to perform for me.

Your reactions give us information.

We can slow down.

We can stop.

We can resource.

We can change course when clinically appropriate.

You are not doing this alone.

As discussed during EMDR consultations I provide to my consultees , clinician confidence tends to increase with experience, and greater clinician comfort can also help clients feel more comfortable with the process.

The Core Message

If a client remembers nothing else from your explanation, I want them to understand this:

Your brain and body are not the enemy.

The reactions that developed after trauma often made sense in the context in which they developed. EMDR is helping your brain recognize that circumstances have changed.

You don't have to know where every thought comes from. You don't have to control every memory. You don't have to get rid of every emotion. You don't have to do EMDR perfectly. You notice. You stay connected to the present. You allow your brain to make connections. And little by little, something that once felt like it was still happening can begin to feel like something that happened.

Looking for Support as You Grow Your EMDR Practice?

Learning the EMDR protocol is only the beginning. Developing confidence in how you explain EMDR, conceptualize complex cases, navigate stuck processing, and determine when to move forward (or when to slow down) often happens through consultation and continued clinical practice. I offer individual and group EMDR consultation for EMDR-trained mental health professionals who want a supportive space to strengthen their clinical skills, ask questions, work through challenging cases, and become more confident and intentional in their use of EMDR. Consultation can be tailored to where you are in your EMDR practice. Learn more about EMDR consultation with Melissa Londry, LPC, or reach out to schedule an individual consultation or join an upcoming consultation group.
