Memory and Trauma, Why Your Mind Forgets What Your Body Never Does
If you’re reading this, you might be wrestling with memories that don’t behave the way you expect them to.
Some moments feel razor-sharp. Others feel missing. You might doubt what you remember, or feel overwhelmed when fragments surface out of nowhere. Many people tell me, “I don’t know what’s wrong with me. My memories feel foggy… scattered… unreliable.”
What I want you to know is this:
There is nothing wrong with you.
Your mind and body are responding exactly as they were designed to under threat.
Trauma changes memory. Not because you’re weak, but because your nervous system is built to protect you, even if the “danger” is long past.
Your Nervous System Remembers Before You Do
When something overwhelming or terrifying happens, your brain shifts into survival mode. The amygdala — your alarm system — takes over. The hippocampus, which helps create coherent memories, becomes disrupted. And your body stores sensations, feelings, and threat responses long before your thinking brain has words for what happened.
This is why trauma is often felt before it is remembered.
If you’ve ever wondered why certain events feel strangely vivid while whole periods are blank, or why your body reacts faster than your mind, this is the reason.
If you want a deeper explanation of how overwhelming stress reshapes your system, you may find my piece on the Window of Tolerance helpful.
When Your Body Remembers What Your Mind Can’t
Think about how a familiar smell can bring back a childhood memory in an instant. Trauma memories work the same way — except instead of nostalgia, the trigger brings panic, nausea, tightness, or rage.
You might not consciously remember why a certain voice, smell, or tone of voice makes you freeze, but your nervous system does. This isn’t an overreaction. It’s recognition.
Your body is trying to protect you based on past threats.
For many survivors, these reactions develop in relationships where gaslighting or emotional abuse made it unsafe to trust their own perception.

Two Types of Memory Trauma Disrupts
1. Narrative Memory: the story of what happened
This is what you can consciously recall: the facts, timeline, events. Trauma often fragments this. You might forget key details or whole chunks of time.
This isn’t because you’re unreliable. It’s because your brain saved your life.
2. Implicit Memory: what your body stores
This is sensation, emotion, posture, tone of voice, the way your stomach tightens when someone raises their voice. It’s not stored in words. It’s stored in the nervous system.
These body-held memories often resurface as:
sudden fear
shutting down
flashbacks
emotional overwhelm
a sense of “something is wrong”
These aren’t failures. They are signals.
When Everyday Life Feels Harder Than It Should
Trauma doesn’t just affect the past — it affects daily life.
You might:
walk into a room and forget why you entered
lose track mid-sentence
feel foggy or scattered
miss appointments
feel like your brain is running slow
Many survivors say it feels like their mind is “full” even when they aren’t thinking about anything. That’s because the nervous system is running a huge internal program in the background — scanning, bracing, protecting.
To understand this survival state, you might find my blog on Trauma Bonding insightful, especially if your trauma is relational.
The Invisible Work Your Brain Is Doing
During trauma, the brain floods with stress hormones (adrenaline, cortisol) that prioritise survival over memory. The hippocampus stops encoding experiences in a smooth, linear way.
Instead of a story, you get fragments.
Instead of clarity, you get fog.
Instead of certainty, you get doubt.
This is why survivors often say: “I can remember the colour of the carpet… but not the sequence of events.”
Or: “I don’t remember what happened, but I remember how terrified I felt.”
None of this means you’re broken. It means your brain was trying to cope with the unbearable.
Some memories sharpen, others fade. Trauma often blurs the line between the two.
Why Triggers Appear “Out of Nowhere”
A song.
A scent.
A look.
A crowded room.
A slammed cupboard.
Someone standing too close.
Triggers come from sensory information, not logic.
This is why understanding your triggers — gently, without judgement — is a crucial part of healing. You don’t need to make yourself feel less. You need to understand what your body is trying to tell you.
To support this work, you may resonate with my post on Glimmers: Small Moments of Safety
which explains how your system recognises cues of safety, too.
Small Things That Actually Help
Gentle Record-Keeping
You don’t need detailed journaling. Even a line or two helps create coherence over time.
Predictable Routines
When your inner world feels unpredictable, external structure can feel grounding.
Anchor Into Your Body
Notice your feet on the ground. Your breath. The way your hands feel. Your senses always bring you back to the present.
Co-Regulation
Healing doesn’t happen in isolation. Connection — with a therapist or safe other — literally reshapes your nervous system.

There’s No “Finish Line” to Trauma Recovery
Healing isn’t about restoring your memory to how it “used to be.” It’s about integrating what happened in a way that no longer overwhelms your nervous system.
Some days you’ll feel clear.
Some days you’ll feel foggy.
Some days you’ll feel like you’ve gone backwards.
You haven’t.
Healing is non-linear because the nervous system is non-linear. You’re not failing — you’re unfolding.
You’re Already Doing Better Than You Realise
If you’re trying to understand your memory, that is healing.
If you’re noticing patterns, that is healing.
If you’re responding to yourself with even a small amount of gentleness — that is healing.
Your memory may not be cooperating yet, but your body is telling the truth, and it has been telling it for a long time.
You’re not broken.
You’re human.
And you don’t have to make sense of this alone.

It’s common to have gaps or fragmented memories after trauma. This is your brain’s natural protective mechanism called dissociative amnesia, where difficult memories are temporarily blocked to shield you from overwhelming pain. It’s not a sign of weakness or forgetfulness but a survival strategy your nervous system uses to keep you safe.
-
These are called triggers. During trauma, your brain encodes not just the event but also sensory details like smells, sounds, or sights. These sensory memories can unexpectedly activate the emotional and physical response stored with the trauma, leading to flashbacks or intense feelings. Understanding your triggers can help you develop strategies to manage them safely.
-
Absolutely. Trauma disrupts how the brain processes and stores memories, often resulting in fragmented, unclear, or jumbled memories. This can cause confusion and difficulty trusting your recollections. Over time, with therapeutic support and self-compassion, clarity can improve.
-
Trauma can affect concentration, decision-making, emotional regulation, and relationships. You might find yourself forgetting appointments, feeling detached, or overwhelmed by simple tasks. These are understandable responses to the ongoing stress your body and mind are managing.
-
Some helpful approaches include:
Journaling to externalise and organise thoughts and feelings
Grounding techniques to reconnect to the present moment
Establishing routines that create predictability and safety
Seeking social support from trusted people or trauma-informed professionals
Remember, coping is a skill built over time, so be patient with yourself.
-
Yes. Trauma-informed therapy provides a safe space to explore memories at your pace. Techniques like narrative therapy, EMDR, or somatic experiencing can facilitate the integration of fragmented memories and the healing of associated emotions.
-
Flashbacks are your brain’s way of reliving trauma as if it’s happening again. They’re often accompanied by strong physical sensations because trauma memories are stored in both the brain and body. Grounding strategies and therapeutic support can help reduce their intensity and frequency.
-
Yes. Healing is a gradual process, and many people find that with the right support and self-care, memory disruptions lessen, emotional regulation improves, and life becomes more manageable. It’s important to honour your unique pace and be gentle with yourself through this journey.
-
If memory difficulties cause significant distress, interfere with your daily life, or if flashbacks and triggers feel overwhelming, it’s beneficial to seek support from a trauma-informed counsellor or therapist. Early intervention can help you develop tools to manage symptoms and promote healing.
-
Loved ones can offer patience, validation, and consistency. Avoid pressuring for details or “forcing” memories to come back. Instead, create a safe, non-judgmental environment where the person feels seen and heard. Encouraging professional help is also vital.
If any of these questions resonate with you or raise new ones, I welcome you to reach out. Healing is possible, and you don’t have to do it alone.
