When the Past Won't Stay in the Past: A Psychologist's Guide to Healing from Intrusive Traumatic Memories

You're sitting at your desk, focused on work, when suddenly you're not there anymore. You're back there, in that moment you've tried so hard to forget. Your heart races. Your hands shake. The memory plays like a movie you never asked to watch, complete with sights, sounds, and that same crushing feeling in your chest.
And then, as quickly as it came, you're back in the present. Disoriented. Exhausted. Maybe a little embarrassed if anyone noticed. Definitely frustrated that after all this time, it still has this power over you.
If this sounds familiar, I want you to know something right now: You're not broken. Your brain is actually doing exactly what it's designed to do, it's just doing it at the wrong time.
As a psychologist who works with trauma survivors, veterans, first responders, and people carrying invisible wounds, I've walked alongside hundreds of people through this exact struggle. And I've learned that understanding why this happens is the first step toward healing.
Why Traumatic Memories Feel Different
Normal memories fade. They become stories we tell, with a beginning, middle, and end. We can recall them without reliving them.
Traumatic memories are different. They don't get properly filed away in your brain's memory system. Instead, they stay "live", unprocessed, fragmented, and hyperaccessible. Your brain treats them like current threats, not past events.
This is why:
- A smell can transport you instantly back to the worst moment of your life
- You can feel the trauma in your body, not just remember it in your mind
- The memory doesn't feel like it happened "back then", it feels like it's happening right now
- Your body reacts as if you're in actual danger, even though you're safe
This isn't a character flaw. It's neurobiology.
What Doesn't Work (And Why You Need to Stop Trying)
Before we talk about what helps, let's talk about what doesn't, because I see too many survivors wearing themselves out with strategies that actually make things worse:
❌ "Just don't think about it" Thought suppression doesn't work. Research shows that trying to push memories away actually makes them come back stronger. It's like telling yourself "Don't think about a pink elephant", guess what you're now thinking about?
❌ "Stay busy so you don't have time to remember" Avoidance gives temporary relief but prevents healing. Plus, you can't stay distracted forever. Eventually, the memory finds you, often when you're most exhausted and least prepared.
❌ "I should be over this by now" There's no timeline for trauma. Shaming yourself for still struggling only adds another layer of pain on top of the original wound.
❌ "I just need to be stronger" You ARE strong. You survived. Healing from trauma isn't about willpower; it's about processing what happened in a way your brain can finally file it away as the past.
What Actually Helps: Five Grounding Strategies for When Memories Intrude
1. Name What's Happening
When you feel yourself slipping into a traumatic memory, say out loud (or in your mind): "This is a memory. I am not in danger right now. I am [your name], and I am [current location], and it is [current date]."
Why this works: You're activating the logical, present-oriented part of your brain (prefrontal cortex) to override the alarm system (amygdala) that's stuck in the past.
2. Use the 5-4-3-2-1 Technique
Identify:
- 5 things you can SEE
- 4 things you can TOUCH
- 3 things you can HEAR
- 2 things you can SMELL
- 1 thing you can TASTE
Why this works: This anchors you in the present moment through your senses. Trauma pulls you into the past; grounding pulls you back to now.
3. Change Your Body Position
If the memory hits while you're sitting, stand up. If you're lying down, sit up. Walk to a different room. Place your feet flat on the floor and press down. Hold ice cubes. Splash cold water on your face.
Why this works: Trauma lives in the body. Changing your physical position sends signals to your nervous system that you're in a different situation than the traumatic event.
4. Breathe Differently (Not Just "Deep Breaths")
Try box breathing: Inhale for 4 counts, hold for 4, exhale for 4, hold for 4. Repeat 4 times.
Why this works: This activates your parasympathetic nervous system (your body's "calm down" system) and gives your brain something specific to focus on besides the memory.
5. Talk to the Memory
This might sound strange, but try this: When the memory comes, say to it (internally or out loud): "I see you. I know you're trying to protect me. But I'm safe now. You can rest."
Why this works: Traumatic memories often intrude because your brain is trying to keep you safe by staying hypervigilant. Acknowledging the protective intent can sometimes help the memory quiet down.
The Longer-Term Healing Work
While these grounding techniques are essential for managing intrusive memories in the moment, true healing requires processing the trauma itself. This typically means working with a trauma-informed therapist trained in evidence-based approaches like:
- EMDR (Eye Movement Desensitization and Reprocessing): Helps your brain reprocess traumatic memories so they're stored like normal memories
- CPT (Cognitive Processing Therapy): Addresses unhelpful beliefs that developed because of the trauma
- PE (Prolonged Exposure): Gradually reduces the power of trauma memories through controlled, supported exposure
- Somatic therapies: Work with the trauma stored in your body
I know therapy feels like a big step. But here's what I want you to understand: You don't have to carry this alone. And you don't have to carry it forever.
A Word About Shame
Many of my clients feel ashamed that they're "still dealing with this." They compare their trauma to others and decide theirs "wasn't bad enough" to warrant this much struggle.
Let me be clear: Your trauma is valid, regardless of whether it looks like someone else's. Your pain is real, regardless of whether others understand it. Your need for healing is legitimate, regardless of how long it's been.
Some of the most debilitating trauma I've seen hasn't been from single catastrophic events, it's been from chronic relational wounds, emotional abuse, betrayal, or living in sustained fear. Trauma isn't measured by what happened. It's measured by how it affected you.
Moving Forward
Healing from trauma isn't linear. Some days will be harder than others. Some memories will take longer to lose their power. That's not failure, that's the reality of recovery.
But here's what I've seen over and over again in my work: People do heal. Memories do lose their intensity. You can get to a place where the past stays in the past.
It takes courage, support, and the right tools. But it's possible.
If you're struggling with intrusive traumatic memories, please know:
- This is treatable
- You deserve support
- Asking for help is strength, not weakness
- There is hope on the other side of this
