How to Stop Thinking About a Bad Memory

Willpower alone rarely works: forcing a bad memory out of your mind tends to make it louder, not quieter. What helps more: ground yourself first, then use short rounds of bilateral stimulation (BLS), the left-right technique used in EMDR, to ease its emotional charge. Go slow, and stop if distress climbs past 7 out of 10.

It’s midnight, or you’re stuck in traffic, or you’re in the middle of something unrelated, and there it is again: the argument, the accident, the thing you said, the thing that was said to you. You didn’t call it up. It just showed up, uninvited, and the harder you try to shove it back out, the louder it seems to get.

Why won’t a bad memory just leave you alone?

Part of the problem is the strategy itself. In a classic 1987 study described by the American Psychological Association, psychologist Daniel Wegner asked people to spend five minutes not thinking about a white bear. Almost no one could do it, and when the group was later allowed to think about the bear freely, they thought about it even more than people who had never been told to suppress it. Fighting a thought now can make it rebound harder later, a big reason “just stop thinking about it” rarely works once a memory has real weight behind it.

The other part is what the memory feels like while it’s happening. Researchers Anke Ehlers and David Clark, in an influential 2000 paper on how the mind processes trauma, describe intrusive memories as carrying a “here and now” quality: vivid, sensory, and disconnected from the context that would remind you it’s actually over. An ordinary memory is something you recall and set back down. A memory stuck on replay hasn’t been filed away as something that happened; part of it still feels like it’s happening.

EMDR’s own theory, the Adaptive Information Processing model, frames this as a storage problem: intensely distressing moments can get locked in a raw, unprocessed form, according to EMDRIA, the professional body for EMDR. That’s also the pattern behind PTSD, where intrusive memories are a defining feature. If a specific memory keeps resurfacing with real intensity, our guide to EMDR and PTSD covers what the research says about that fuller picture.

Ground yourself before you try anything else

Before you engage with the memory at all, spend a minute somewhere calmer. Picture a real or imagined place where you feel safe, or run a quick grounding check: name five things you can see, feel your feet on the floor, slow your exhale. Staying inside your window of tolerance, the zone where a memory is present but you can still think clearly, is what makes the next steps useful instead of overwhelming. Don’t start this already flooded.

Go slow: one memory, not the whole story

Pick a single moment, not the entire relationship, event, or chapter of your life. “The way he looked at me when he said that” is workable. “Everything about that year” is too large to hold steady while you work with it. Keep sessions short, just a few minutes, and expect to come back to it more than once rather than settling it in one sitting.

Know your stop point

If your distress rises above a 7 out of 10 and doesn’t settle back down, stop. Use grounding, and consider working with a professional rather than pushing through alone. That’s useful information about how much weight this particular memory carries, not a sign you’re doing it wrong.

A short bilateral stimulation practice for a memory on replay

With those three pieces in place, here’s a short round of bilateral stimulation, the rhythmic left-right technique at the center of EMDR:

• Rate it. On a 0–10 scale, how strong is the charge right now, just touching the edge of the memory? Note the number.
• Bring it lightly to mind. The image, the moment, the feeling. Touch it, don’t dive into the most intense version of it.
• Add bilateral stimulation. Move your eyes smoothly left and right for 20 to 30 seconds, tap your knees or shoulders left-right (the “butterfly hug”), or use alternating left-right audio tones if you have headphones.
• Pause and notice. Stop. Breathe. Notice whatever shifted, a bit of distance, a duller edge, a physical release, without forcing anything.
• Repeat 3 to 5 short rounds, checking in between each one.
• Re-rate. Check your number again. Many people notice it easing. If it climbs instead and won’t come back down, stop and ground yourself; that’s fine to leave for another day.

Counting rounds and pacing yourself while a memory is already loud is one more task than most people want to manage alone. EmEase, a self-guided EMDR app, runs the same left-right technique for you with a moving on-screen target or alternating tones, paced however you like, in the web app. The beginner’s guide to self-guided bilateral stimulation walks through pacing and choosing a method.

Does this actually help, or is it just distraction?

There’s real, if partial, evidence behind it. A 2020 meta-analysis of 15 laboratory studies in the Journal of Experimental Psychopathology, pooling 942 participants, found that eye movements meaningfully reduced both the vividness and emotional intensity people rated for a distressing memory held in mind. The leading explanation is that eye movements, and other demanding dual tasks, tax your limited working memory, so a memory held alongside them comes through less vivid and less charged. The same mental resources can’t fully do both jobs at once.

A striking real-world version of this idea comes from emergency medicine. In a 2018 trial led by psychologist Lalitha Iyadurai, published in Molecular Psychiatry, researchers had patients briefly recall a memory cue from a recent real-world trauma, then spend time playing Tetris, a visually demanding game, while still in the emergency department. Patients who did this had fewer intrusive memories of the event in the days that followed than patients in a control group who didn’t. That study tested a different moment (fresh trauma, a hospital setting) than a memory you’ve carried for a while, but it points to the same underlying idea: giving your visual working memory something demanding to do can loosen a memory’s grip.

None of this erases the memory. It’s a plausible, low-risk way to take some heat out of it, not a rewrite of what happened.

When does a bad memory need more than this?

This practice is built for everyday, non-dangerous memories: the ones that intrude and sting but don’t involve real threat. Consider working with a licensed therapist, ideally one trained in EMDR, if:

• The memory involves real danger, like abuse, an assault, a serious accident, or combat.
• Intrusions happen often enough to disrupt your sleep, work, or relationships.
• You notice dissociation (feeling unreal or checked out), flashbacks, or panic that frightens you.
• During the practice above, distress climbs past a 7 out of 10 and won’t settle.
• The memory brings on hopelessness or thoughts of harming yourself. That’s outside what self-guided practice is built for. A licensed professional, or our crisis resources page, is the safer next step.

In any of these, a trained therapist can help you process the memory itself far more safely than working alone. Our guide to calming triggers and distressing memories is a good next stop if this feeling shows up around more than one memory at a time. If what you’re noticing is closer to a flashback than a memory, our step-by-step guide to grounding during a flashback goes deeper on that piece. And if what’s stuck on replay is something excruciating rather than frightening, like something you said or did, Replaying Embarrassing Memories covers that specific flavor of loop.

A memory that won’t stop replaying isn’t a character flaw or a failure of willpower. It’s information about how much weight it’s carrying, and settling it, even partway, is real progress.
