Can EMDR Create False Memories?

Not out of nothing, under standard use. No solid evidence shows well-delivered EMDR fabricates whole memories that never happened. The real, documented risk is narrower: certain conditions show eye movements can affect memory accuracy, and any memory-focused technique, EMDR included, becomes genuinely risky when it’s combined with suggestive practices, especially hunting for memories someone believes are “repressed.”

Maybe you read a headline calling EMDR “junk science” for memory, or a friend warned you it can make you believe things that never happened. Or you’re about to start self-guided bilateral stimulation and want a straight answer before you do. The research here is genuinely mixed, and it’s worth walking through honestly rather than flattening it into a simple yes or no.

Where does this concern come from?

The worry isn’t invented from nothing. A 2021 review in the journal Memory by Otgaar, Houben, Rassin, and Merckelbach raised a specific concern. Many EMDR practitioners endorse the idea that trauma memories can be fully blocked from awareness and later recovered intact, a claim mainstream memory science treats as unproven. The review warned this belief, paired with imagery-based memory work, could create real problems if a client’s memory later matters in court.

A 2025 survey of 178 UK mental-health professionals found that belief is still common. More than three-quarters endorsed the idea that memories can be repressed, and EMDR-trained respondents showed the strongest agreement, 91 percent, that “blocked out” memories cause later dissociation or physical symptoms. Believing repression is possible isn’t dangerous by itself. It becomes a problem when it shapes how a therapist asks questions about a memory that hasn’t surfaced yet.

Do the eye movements themselves distort memory?

Separately from clinician beliefs, researchers have tested whether EMDR’s eye-movement component affects memory accuracy on its own. In a 2018 study in Clinical Psychological Science, Houben, Otgaar, Roelofs, and Merckelbach had people watch a car-crash video, then exposed them to misleading details about it. Participants who made eye movements afterward were less accurate and more likely to accept the false details than those who kept their eyes still.

That finding hasn’t held up cleanly, and the nuance matters. A 2019 direct-replication attempt in the same journal by van Schie and Leer ran the same design and found no increase in false memories from eye movements at all. The honest read: eye movements alone aren’t established to reliably distort memory, but the question isn’t fully closed either. That’s part of why courts and clinicians treat EMDR carefully when someone’s memory might later matter as testimony.

So does standard EMDR create false memories?

Largely, no, and the distinction is worth understanding. A 2024 paper in Frontiers in Psychology by Callus, Gallina, and Fernandez pushed back directly on the “false memory creation” framing, arguing it doesn’t match how standard EMDR is actually built. In the standard protocol, the client, not the therapist, determines what a memory means and whether it feels valid; the therapist isn’t supposed to interpret or lead.

That structure matters because of what EMDR actually targets. Per EMDRIA, EMDR’s professional association, the Adaptive Information Processing model behind the therapy treats a memory as an existing, stuck network, not a blank page to fill in. And unlike what some people assume, EMDR doesn’t erase or rewrite a memory’s content either; it targets a specific incident someone already remembers and wants to feel less disturbing, not content they can’t currently access.

That’s a different situation from actively searching for a memory someone suspects exists but can’t recall, sometimes called “recovered memory” work. That specific practice, not the standard EMDR protocol, is where the false-memory research raises the most concern, no matter which therapy label is attached to it.

What does this mean for practicing bilateral stimulation on your own?

One rule keeps self-guided practice on the safe side of this whole debate: work only with a memory or feeling you already know is real, not one you’re trying to uncover, confirm, or piece together. Bilateral stimulation is a way to ease the charge on something you already remember, not a tool for figuring out whether something happened.

Before working with any memory, stabilize first: spend a minute in a calm place in your mind. Then go slow, one memory or feeling at a time, in short sessions. And know your stop point: if distress rises above a 7 out of 10 and won’t settle, stop, ground yourself, and consider working with a professional instead.

With that in place, here’s a short practice for a memory you already know:

• Rate it. On a 0–10 scale, how disturbing does this memory or feeling feel right now?
• Bring it to mind gently, just as you already remember it, without searching for missing pieces.
• Add bilateral stimulation. Move your eyes slowly side to side for 20–30 seconds, or tap alternating knees or shoulders.
• Pause and notice what shifted, without forcing an interpretation onto it.
• Repeat 3 to 5 short rounds, checking the number again each time.

EmEase, a self-guided EMDR app, applies this same technique to everyday stress and to memories you already recognize, at your own pace at app.emease.com. The safe use of any self-guided bilateral-stimulation practice, EmEase included, is working with what you already remember, not searching for what you don’t.

When does this need a professional instead?

Bring in a trained therapist rather than continuing alone if:

• You suspect a memory exists that you can’t currently access, or you’re trying to figure out “what really happened”
• The memory might matter in a legal setting, like a case that could go to court
• You feel pressure, from yourself or someone else, to interpret a vague image or sensation as proof of a specific event
• Distress spikes and won’t settle, or you notice dissociation, like feeling foggy or unreal

Is self-guided EMDR safe? covers that boundary in more depth generally, and who should not do EMDR on their own goes further into specific red flags.

So, can EMDR create false memories?

Not from thin air, under standard practice, and not because eye movements have been reliably shown to invent content on their own. The real risk lives in suggestive technique and the search for memories someone isn’t sure ever happened, not in the modality itself. For self-guided bilateral stimulation, the safeguard is simple: stay with what you already know and remember, go slowly, and bring anything murkier to a trained professional instead of trying to sort it out alone.
