Strong emotions can surface during EMDR because treatment intentionally brings distressing memories, thoughts, feelings, or physical sensations into awareness. Feeling emotionally activated does not automatically mean something is going wrong. Your therapist can monitor your response, adjust the pace, pause processing, and return to preparation when more support is needed.
Some people begin EMDR worried that difficult memories will feel overwhelming. Others are surprised when a target memory brings up tears, fear, anger, tension, or a sense of shutting down.
These reactions can feel intense, especially when the memory is connected to trauma or another highly distressing experience.
EMDR therapy in Mississauga is a structured form of psychotherapy. Preparation, assessment, pacing, processing, and closure are all part of the treatment rather than expecting you to push through whatever comes up.
What Does “Emotional Flooding” Mean?
“Emotional flooding” is a common way of describing a level of emotional activation that feels difficult to manage in the moment.
It may include:
- a sudden increase in fear or anxiety
- crying that feels hard to stop
- anger or irritability
- racing thoughts
- strong physical tension
- nausea, shaking, or a racing heart
- feeling mentally blank
- wanting to escape the conversation or session
- feeling numb, distant, or disconnected
Emotional flooding is not a diagnosis by itself.
It is also important not to assume that every strong emotion is a sign of trauma. People can become overwhelmed for many reasons, including anxiety, grief, conflict, exhaustion, or current life stress.
During EMDR, the therapist considers what is happening in the context of your treatment and how well you are able to stay engaged with the work.
Why Can EMDR Bring Up Strong Emotions?
EMDR is trauma-focused therapy.
During reprocessing, you are asked to bring an upsetting memory or part of an experience to mind along with related thoughts, emotions, beliefs, or physical sensations.
The U.S. Department of Veterans Affairs describes EMDR as a treatment in which a person focuses on an upsetting memory while engaging in bilateral stimulation, such as guided eye movements or alternating sounds.
Because you are intentionally working with distressing material, some emotional activation can occur.
A memory might bring up:
- fear associated with the original event
- shame or self-blame
- physical sensations connected with the experience
- grief about what happened
- anger that was difficult to express at the time
- another memory that feels related
That does not mean the memory is literally “stored in the body” or that the nervous system is being mechanically reset. Trauma, memory, emotion, and physical responses are more complex than those simplified explanations suggest.
Does Feeling Overwhelmed Mean EMDR Is Not Working?
Not necessarily.
Some distress can occur during trauma-focused therapy. The more useful question is whether the level of activation remains manageable enough for therapeutic work to continue.
EMDR is not intended to be a test of how much distress you can tolerate.
If you become too overwhelmed to stay present, think clearly, communicate with your therapist, or continue engaging with the target, the therapist can adjust the session.
This may mean:
- slowing the pace
- pausing bilateral stimulation
- returning attention to the present
- reviewing coping strategies
- changing the target
- spending more time in preparation
- ending reprocessing for that session
EMDRIA describes preparation as a formal phase of EMDR that includes education, therapeutic alliance, coping strategies, and affect-regulation skills. Some clients need more preparation before moving into reprocessing. (EMDRIA)
What Happens Before Reprocessing Begins?
EMDR does not normally begin with the therapist immediately asking you to focus on the most distressing memory.
The early phases include history taking, treatment planning, and preparation.
Your therapist may explore:
- what brings you to therapy
- current symptoms
- relevant past experiences
- present-day triggers
- coping resources
- current supports
- whether certain memories feel appropriate to target
- how you usually respond when emotions become intense
You should also understand what EMDR involves and have a way to communicate when you need to pause.
If readiness is a particular concern, our guide to preparation and stabilization before EMDR explains this stage in more detail.
How Can a Therapist Respond to Emotional Flooding During EMDR?
A therapist should not assume that every strong reaction needs to be pushed through.
EMDR is collaborative.
You can tell your therapist if:
- the memory feels too intense
- you feel disconnected from the present
- you are struggling to follow what is happening
- physical sensations become difficult to manage
- you want to pause
- you are worried about how you will feel after the session
The therapist can then decide with you whether to continue, slow down, return to preparation, or change the treatment plan.
EMDRIA’s guidance on preparation emphasizes collaboration, informed consent, affect regulation, and the client’s ability to communicate what they are experiencing during reprocessing.
This is one reason therapist fit matters. You should feel able to say when something is not manageable rather than believing you need to perform EMDR “correctly.”
Does EMDR Always Require Extensive Stabilization First?
No, Preparation is part of standard EMDR, but the amount of preparation differs from person to person.
Some people have strong coping resources and are ready to move into reprocessing relatively quickly.
Others may benefit from more preparation because of factors such as:
- difficulty remaining present when distressed
- significant current instability
- frequent dissociation
- limited coping strategies
- complex clinical concerns
- difficulty returning to baseline after activation
The goal is not to delay trauma work indefinitely.
It is to create a treatment plan that reflects your current needs rather than following a fixed number of preparation sessions.
What Can You Do If You Are Worried About Becoming Overwhelmed?
Tell your therapist before processing starts.
Useful questions include:
- “What happens if I become overwhelmed?”
- “How will we know when to pause?”
- “Can I stop bilateral stimulation if I need to?”
- “How do you decide whether I am ready for reprocessing?”
- “What should I do if strong emotions continue after the session?”
- “How will we adjust treatment if I start shutting down or disconnecting?”
These questions can help you understand how collaborative the therapist’s approach is.

How Does EMDR Work With the Memory After Preparation?
When you and your therapist decide to begin reprocessing, a specific target is selected.
You may be asked to notice:
- an image or part of the memory
- a negative belief
- the emotion connected with it
- physical sensations
- the level of distress
Bilateral stimulation is then used while you attend to aspects of the target.
The therapist checks what you notice between sets and continues to monitor how the session is progressing.
Our guide to how EMDR reprocesses traumatic memories explains this part of treatment in more detail.

Frequently Asked Questions
Yes, strong emotions can surface because EMDR involves focusing on distressing memories and related thoughts, feelings, or physical sensations. Your therapist should monitor your response and can adjust the pace if the level of distress becomes difficult to manage.
Tell your therapist. Processing can be paused or slowed, and the session can return to grounding, preparation, or another strategy. Becoming overwhelmed does not mean you have failed EMDR or need to keep pushing through.
Not automatically. Strong activation can have many meanings. Your therapist should assess what happened, your ability to stay present, your current stability, and whether the treatment plan or level of preparation needs to change.
No. The goal is not to eliminate all anxiety or difficult emotion before reprocessing. Readiness is individualized and includes being able to engage with treatment, communicate with your therapist, and use enough support to work with distressing material.
Online EMDR can be appropriate for some adults, but suitability depends on privacy, safety, symptoms, technology, environment, and clinical needs. Discuss your concerns with the therapist so they can determine whether virtual or in-person treatment is the better fit.
