When the past still feels like the present
Trauma does not always stay neatly in the past.
You may know intellectually that something happened years ago, that you are safe now, and that the person, place, relationship, accident, or situation is no longer occurring—but your body may respond as though it is happening again.
A sound, smell, facial expression, conflict, physical sensation, location, relationship dynamic, or even a particular thought can suddenly trigger an intense reaction.
Your heart may race.
Your muscles may tense.
You may feel an overwhelming urge to escape.
You may become angry or defensive.
You may shut down or feel numb.
You may experience panic, shame, dread, or a sense that something terrible is about to happen.
These reactions are not signs that you are weak, irrational, or "stuck in the past."
They often indicate that your nervous system learned something was dangerous—and has not yet fully learned that it is over.
This is one of the central ideas behind Eye Movement Desensitization and Reprocessing (EMDR) therapy. EMDR helps people process distressing memories and experiences so they become less emotionally and physically overwhelming. It is well established as a treatment for post-traumatic stress disorder (PTSD), and research continues to examine its usefulness for other psychological difficulties.

What happens when something traumatic occurs?
Our brains and nervous systems are designed to protect us. When we encounter danger, the body can rapidly shift into a survival response.
The classic responses are often described as:
Fight: The nervous system prepares you to confront the threat.
You may experience:
Flight: The body prepares to escape.
You may experience:
Freeze: Sometimes fighting or escaping doesn't seem possible.
The nervous system may instead reduce movement and engagement. You might feel:
People sometimes experience another related response called fawn, in which they try to maintain safety by appeasing, accommodating, or excessively focusing on another person's needs.
These are not conscious decisions in the ordinary sense. They are protective responses.
The nervous system is essentially asking: "What do I need to do right now to survive?"
The classic responses are often described as:
Fight: The nervous system prepares you to confront the threat.
You may experience:
- anger or irritability
- increased muscle tension
- a strong need to defend yourself
- feeling argumentative or aggressive
- a powerful sense of "I have to do something"
Flight: The body prepares to escape.
You may experience:
- anxiety or panic
- racing thoughts
- restlessness
- a strong urge to leave
- difficulty relaxing
- constantly scanning for what might go wrong
Freeze: Sometimes fighting or escaping doesn't seem possible.
The nervous system may instead reduce movement and engagement. You might feel:
- unable to move or speak
- mentally blank
- detached
- numb
- frozen in place
- disconnected from your emotions or surroundings

How does EMDR work?
The honest answer is:
We know that EMDR can be effective for PTSD, but scientists are still investigating exactly why it works.
One influential explanation comes from the Adaptive Information Processing (AIP) model.
According to this model, the brain normally processes and integrates experiences into a broader network of memories, knowledge, emotions, sensations, and beliefs. For example, after an ordinary embarrassing or uncomfortable experience, you might eventually think: "That was uncomfortable, but I survived it. I learned something from it. It's over."
A highly overwhelming experience may not integrate in the same way. Instead, aspects of the experience may remain strongly connected to:
EMDR aims to help the brain reprocess the memory so that it becomes less disturbing and more integrated.

- physical sensations
- emotions
- negative beliefs about yourself
- sounds or smells
- feelings of helplessness
- expectations about what might happen next
EMDR aims to help the brain reprocess the memory so that it becomes less disturbing and more integrated.
What does "reprocessing" mean?
Reprocessing does not necessarily mean repeatedly telling the entire traumatic story. EMDR does not require prolonged exposure to the trauma narrative in the same way that some other approaches do. You may still experience emotions, sensations, memories, and thoughts during processing, but the therapist helps you work with the memory rather than simply asking you to repeat the story. Some people find this approach more tolerable.
In EMDR, the therapist helps you bring aspects of a disturbing memory into awareness while maintaining dual attention—for example, following the therapist's hand with your eyes or attending to alternating sounds or taps. The therapist guides the process rather than telling you what you should think or feel.
As the memory is reprocessed, people may notice that:

As the memory is reprocessed, people may notice that:
- the image becomes less vivid
- the emotional intensity decreases
- body sensations change
- new information or perspectives emerge
- the memory feels more distant
- negative beliefs become less convincing
- the event feels more like something that happened in the past
EMDR is not about convincing yourself that "it wasn't that bad"
Trauma therapy is sometimes misunderstood as trying to make someone think positively about something terrible that happened.
That isn't EMDR's purpose. If something harmful happened, therapy doesn't require you to decide it was acceptable.
Instead, processing may help your brain separate what happened then from what is happening now.
For example, someone might begin therapy with beliefs such as:
The therapist does not simply tell you to believe these things.
The aim is for EMDR to allow new information and perspectives to become emotionally believable.

- "It was my fault."
- "I have no control."
- "I can't trust anyone."
- "I'm powerless."
- "There is something wrong with me."
- "I survived."
- "It wasn't my fault."
- "I have choices now."
- "I can protect myself."
- "I am safe in this moment."
- "What happened does not define me."
The therapist does not simply tell you to believe these things.
The aim is for EMDR to allow new information and perspectives to become emotionally believable.
EMDR isn't about forgetting
One of the most important things to understand is that successful trauma treatment does not necessarily mean forgetting what happened.
The goal is not: "I don't remember anymore."
It is closer to: "I remember, but I don't relive it."
You may still know that something painful happened. You may still wish it had never happened. You may still feel sadness, anger, grief, or other emotions.
But the memory no longer has the same ability to take over your nervous system or determine how you experience the present.
The past can become part of your story without continuing to control your present.

What does an EMDR session look like?
EMDR is an eight-phase therapy. It is not simply an exercise involving eye movements.
The phases include:
The phases include:
- History and treatment planning
The therapist learns about your history, current difficulties, strengths, resources, and treatment goals. - Preparation
You learn what to expect and build skills to manage emotional activation. Establishing safety and a strong therapeutic relationship is important. - Assessment (Activation)
You and your therapist identify a specific memory or other target and explore associated images, beliefs, emotions, and body sensations. - Desensitization
Bilateral stimulation is used while you attend to aspects of the disturbing material. - Installation
You strengthen a more adaptive belief or perspective. - Body scan
You notice whether distress or physical sensations remain associated with the memory. - Closure
The therapist helps you return to a stable state before ending the session. - Reevaluation
You reevaluate your chosen target or memory to determine next steps.
How long does EMDR take?
There is no single answer because the amount of treatment depends on the person and the complexity of the trauma. EMDR is often delivered effectively in a relatively limited number of sessions. The American Psychological Association describes EMDR as typically delivered once or twice weekly for about 6–12 sessions, although some people need less or more. Typical EMDR sessions are approximately 60–90 minutes, although the format can vary.
Someone who has experienced:
The goal should not be speed; instead, it should be effective treatment delivered at an appropriate pace.
Someone who has experienced:
- one isolated traumatic event
- repeated childhood trauma
- years of abuse
- multiple traumatic relationships
- chronic interpersonal trauma
- ongoing unsafe circumstances
- significant dissociation
- multiple overlapping mental-health concerns
The goal should not be speed; instead, it should be effective treatment delivered at an appropriate pace.
Who can EMDR help?
EMDR has its strongest evidence base for PTSD and trauma-related symptoms.
It has been studied with people who have experienced many different forms of trauma, including:

- childhood abuse
- sexual assault
- domestic violence
- accidents
- medical trauma
- combat and military experiences
- natural disasters
- serious injury
- sudden or traumatic loss
- witnessing traumatic events
- bullying
- neglect
- other overwhelming or threatening experiences
How do I decide if EMDR is worth exploring?
EMDR may be worth discussing with a therapist if you notice that:
You don't have to be certain EMDR is right for you before making an appointment.
An initial consultation can simply be a conversation about whether the approach fits your needs.
- Certain memories continue to feel as though they are happening "now"
- You know you're safe, but your body doesn't seem to believe it
- Particular situations produce disproportionately strong reactions
- You experience recurring nightmares or intrusive memories
- You avoid people, places, situations, or conversations because they trigger you
- You experience intense fight, flight, freeze, or shutdown responses
- You carry persistent shame, guilt, fear, or helplessness connected to past experiences
- You feel that something from your past continues to influence your relationships or sense of safety
- You have tried talking about what happened but still feel that your body reacts as though it is happening now
- You want a trauma-focused approach but do not want prolonged, detailed exposure to the trauma narrative

Finding the right EMDR therapist
The therapist matters. Look for someone with appropriate professional credentials in your jurisdiction and recognized EMDR training.
It can also be helpful to ask:
A good therapist will not pressure you to disclose more than you are ready to discuss.
It can also be helpful to ask:
- What EMDR training have you completed?
- How much experience do you have treating trauma?
- Do you work with complex trauma?
- How do you approach dissociation or feeling overwhelmed?
- How do you decide when someone is ready for trauma processing?
- What happens if I become too activated during a session?
- How will we know whether EMDR is helping?
- What other therapies might be appropriate for me?
A good therapist will not pressure you to disclose more than you are ready to discuss.
EMDR Approaches
EMDR can be adapted to meet different needs, circumstances, and types of trauma. While standard EMDR therapy is often used to address longer-standing or complex trauma, specialized protocols have been developed for situations such as recent traumatic events, group trauma, and distressing triggers or urges. These approaches use EMDR principles in structured ways to help people process distress, restore a greater sense of safety, and reduce the emotional and physiological impact of difficult experiences.
G-TEP (Group Traumatic Episode Protocol) is a specialized EMDR approach designed to help people process the impact of a shared or collective traumatic experience within a group setting. Rather than asking participants to share the details of their trauma with the group, G-TEP uses structured EMDR exercises that allow each person to work with their own experience privately, while being supported within the group environment. This can provide an opportunity to process distress while also experiencing the reassurance that you are not alone in what you're feeling.
G-TEP may be particularly helpful after events such as natural disasters, accidents, violence, workplace incidents, community tragedies, or other experiences that affect many people at once. The group setting can also help normalize reactions that can follow trauma. Feeling anxious, overwhelmed, disconnected, angry, unable to sleep, or constantly on alert can be a natural response to something frightening or overwhelming. Being around others who have been through the same event can provide connection and understanding.
Recent Traumatic Episode Protocol (R-TEP) is a specialized EMDR approach designed to support people in the early days and weeks following a traumatic experience. It can help reduce the intensity of distressing memories and reactions while supporting the brain's natural ability to process what has happened.
There isn't a specific deadline for using R-TEP. It may help in the days or weeks after a single traumatic event, and you can also consider it when you're experiencing an ongoing or continuing traumatic situation. Your therapist will consider what has happened, how you are responding, your current sense of safety, and whether you feel ready to begin processing.
DeTUR (Desensitization of Triggers and Urge Reprocessing) is a specialized EMDR approach that can help reduce the intensity of these triggers, cravings, and urges. Rather than focusing only on the behaviour itself, DeTUR looks at what happens underneath it. Together with your therapist, you identify the situations, emotions, memories, or body sensations that tend to set off an urge.
EMDR techniques then help reduce the emotional charge connected to those triggers while strengthening a greater sense of calm, safety, and personal choice. The goal isn't to take away your ability to feel emotions or to simply tell yourself to "make better choices." Instead, DeTUR can help create more space between the trigger and the urge to act.
DeTUR has been used particularly in work with addictions and compulsive behaviours, although triggers and urges can take many forms. Your therapist can help determine whether this approach fits what you're experiencing and whether to use it on its own or alongside other therapeutic approaches.
