What Happens in EMDR Therapy? A Gentle Guide to the EMDR Process

What Happens in EMDR Therapy?

If you've been researching trauma therapy, you've probably come across something called EMDR.

Perhaps someone recommended it. Maybe your therapist mentioned it. Or perhaps you've heard stories from friends who say it changed their lives.

Alongside the hope, there's often a lot of uncertainty.

Many people arrive at their first EMDR session feeling nervous. They worry they'll be expected to relive traumatic experiences, lose control of their emotions, or talk about things they're not ready to discuss. Some are concerned that trauma processing will make everything worse before it gets better.

These fears make sense.

The reality, however, is often very different from what people imagine.

EMDR is not about forcing people to revisit painful memories before they're ready. It is a structured, evidence-based approach that helps the brain process experiences that have become "stuck," allowing them to be stored in a way that feels less overwhelming and disruptive.

Before we talk about what happens in an EMDR session, it can be helpful to understand why trauma memories can feel so different from ordinary memories.

Why Do Some Memories Feel Like They Are Still Happening?

Most experiences are gradually processed by the brain and stored as memories.

We remember what happened, but we also recognise that it is over.

Traumatic experiences often work differently.

Instead of being stored as something that happened in the past, parts of the experience can remain trapped in the nervous system. Certain sounds, smells, emotions, sensations, situations, or relationship dynamics can trigger those memories and make them feel surprisingly present.

People often describe this as:

• Feeling as though they are back in the situation

• Reacting more intensely than they would like

• Knowing they are safe but not feeling safe

• Having emotional responses that seem bigger than the current situation

One of the ways I explain this is by imagining that the brain has a filing system.

Most memories are filed away in the correct place. Trauma memories sometimes end up sitting on top of the filing cabinet rather than inside it. They remain easily activated and continue to influence how we experience the present.

EMDR helps the brain finish a process that was interrupted when the original experience occurred.

What Does EMDR Stand For?

EMDR stands for Eye Movement Desensitisation and Reprocessing.

While the name sounds technical, the goal is quite simple: to help the brain process distressing memories in a way that reduces their emotional intensity and allows new understanding to emerge.

Although eye movements are one form of bilateral stimulation, many therapists also use tapping or alternating sounds. The eye movements themselves are not the therapy. They are simply one tool used to support the brain's natural processing abilities.

Phase One: Building Safety and Understanding

One of the biggest misconceptions about EMDR is that trauma processing begins immediately.

In reality, good EMDR therapy starts with preparation.

Before any trauma processing takes place, we spend time understanding your history, current challenges, strengths, supports, and goals for therapy. We explore how trauma may have affected your nervous system and identify the patterns that continue to impact your life today.

For some people, this stage is relatively brief. For others, particularly those with complex trauma or dissociation, this phase may take considerably longer.

There is no prize for rushing.

The goal is to ensure that you have enough stability and support before moving into deeper work.

Phase Two: Developing Resources and Regulation Skills

Before processing traumatic memories, we focus on helping you build skills that support emotional regulation and grounding.

This may include learning how to:

• Recognise signs of overwhelm

• Stay connected to the present moment

• Manage strong emotions

• Understand nervous system responses

• Develop internal and external sources of support

I often explain this phase using a hiking metaphor.

If you were preparing to climb a mountain, you wouldn't begin by heading straight for the steepest section of the track. You would first gather supplies, check your equipment, and make sure you had what you needed for the journey ahead.

Trauma processing is much the same.

Preparation is not separate from the work. Preparation is part of the work.

Phase Three: Trauma Processing

When the time feels right, we begin processing specific memories or experiences that continue to affect your life.

Many people are surprised by how different this feels from traditional talk therapy.

You are not expected to tell the story repeatedly or provide detailed descriptions of everything that happened.

Instead, we identify a memory, belief, emotion, sensation, or image that feels significant. Bilateral stimulation is then used while your brain naturally begins making connections and processing information.

People often report that insights emerge spontaneously during this process.

Memories that once felt overwhelming may begin to feel more distant. Self-blame may soften. New perspectives often emerge without needing to be forced.

Everyone's experience is different, but the overall goal remains the same: helping the memory become something that happened rather than something that continues to happen.

What Does EMDR Feel Like?

This is one of the most common questions I receive.

The honest answer is that EMDR feels different for different people.

Some describe it as surprisingly gentle.

Others describe it as emotionally tiring in the same way that a deep conversation can feel tiring.

Many people notice that memories become less vivid, emotions feel less intense, or they begin understanding their experiences in a new way.

Contrary to popular belief, most people do not lose control during EMDR.

In fact, a significant part of the process involves ensuring that you remain connected to the present and able to manage what arises.

Is EMDR Effective?

EMDR is one of the most extensively researched trauma therapies available and is recommended internationally for the treatment of PTSD and trauma-related difficulties.

Research has shown EMDR can be helpful for:

• PTSD

• Complex trauma

• Anxiety

• Panic

• Phobias

• Grief

• Distressing memories

• Negative self-beliefs

It is important to remember, however, that no therapy is a magic wand.

Healing is not about erasing memories. It is about changing the relationship you have with them.

Every Behaviour Makes Sense

One of the reasons I value EMDR is that it aligns closely with how I understand human behaviour.

Many people arrive in therapy believing there is something wrong with them because they continue reacting to experiences that happened years ago.

What EMDR helps us understand is that these reactions often make perfect sense.

Your nervous system learned something important during those experiences.

The goal is not to force yourself to "get over it."

The goal is to help your brain and body recognise that the danger is no longer present.

Because every behaviour makes sense once we understand the story behind it.

And sometimes healing begins when the story finally has the opportunity to be fully processed.

Frequently Asked Questions

Do I have to talk about everything that happened?

No. EMDR does not require detailed retelling of traumatic experiences.

Can EMDR make things worse?

Strong emotions can arise during trauma work, which is why preparation and pacing are so important. Good EMDR therapy prioritises safety and stability throughout the process.

Is EMDR suitable for complex trauma?

Yes, although people with complex trauma often benefit from a longer preparation phase before trauma processing begins.

How many EMDR sessions will I need?

This varies significantly depending on your history, goals, and the complexity of the experiences being addressed.

Thinking About EMDR?

If you're wondering whether EMDR might be right for you, you're not alone. Many people feel uncertain before beginning trauma therapy.

Sometimes the first step isn't deciding whether EMDR is the answer. Sometimes it's simply having a conversation and exploring what support might look like for you.

You don't need to navigate that journey alone.
