The Relationship Between Hypnosis and Memory Is More Powerful Than Most People Realise

If you have ever found yourself ambushed by a painful memory; a smell, a song, a tone of voice that suddenly drags you back to a moment you would rather forget you already understand on a visceral level how memory and emotion are bound together.

What most people do not realise is that hypnosis has a unique and scientifically supported ability to work directly with this bond. Not to erase memories, but to change the emotional charge they carry. To move them from a place of threat to a place of history.

In this post I aim to give you comprehensive guide to how memory works, why bad memories affect us so deeply, how hypnosis interacts with the brain’s memory systems, and what a skilled hypnotherapist can actually do to help you reclaim your peace of mind.


How Memory Works

The brain does not record memories the way a camera records video. Memory is a reconstructive process. Each time you recall an event, you are not playing it back. You are rebuilding the memory, and in doing so, you have the opportunity to update it.

There are two memory systems particularly relevant to hypnotherapy.

The amygdala is the brain’s alarm system. It processes emotional significance, particularly fear and threat. When something frightening or painful happens, the amygdala stamps that memory with a high-priority emotional tag. This is why you can forget where you left your keys but vividly remember a moment of humiliation from thirty years ago. Neurobiological research published in Dialogues in Clinical Neuroscience confirms that the amygdala plays a central role in encoding emotionally charged memories, and that trauma is associated with lasting increases in amygdala reactivity.

The hippocampus is the brain’s filing system. It organises memories into context, placing them in the past where they belong. When the hippocampus is working well, a painful memory is stored as something that happened, not something that is still happening. Research has shown that PTSD is associated with reduced hippocampal function, which disrupts the brain’s ability to contextualise and archive threatening memories properly.

The problem with trauma is that it disrupts this filing process. Traumatic memories can become stuck in the amygdala, unable to be processed and archived by the hippocampus. They remain raw, vivid, and ever-present. Ready to fire at any moment when triggered by a sound, a smell, a feeling, or even a thought.


Why Bad Memories Carry More Weight Than Good Ones

This is not a personal failing or a sign of weakness. It is evolutionary design.

Bad memories carry more emotional charge than good ones because, from a survival standpoint, they need to. If you survive a dangerous situation, your brain needs to make absolutely sure you remember it so you can avoid that danger in the future. The more intense the emotional response, the more deeply the memory is encoded.

This is known as negativity bias — the brain’s tendency to give greater weight to negative experiences than positive ones. A landmark review in the journal Psychological Science titled “Bad Is Stronger Than Good” found this pattern replicated across many domains. It is why one critical comment can overshadow a hundred compliments, and why a single traumatic event can reshape a person’s entire worldview.

Boston College psychologist Elizabeth Kensinger’s research, published in Current Directions in Psychological Science, found that negative events are remembered in significantly greater detail than positive ones, and that this appears to be an evolved feature of cognition designed to help us avoid repeating dangerous mistakes.

When children grow up in dysfunctional families, they do not just experience bad events, they internalise them. The child’s developing mind concludes that the chaos, the criticism, the neglect, or the abuse must somehow be their fault. This leads to toxic shame; a persistent, crushing sense that there is something fundamentally wrong with you, rather than with what happened to you.

This is explored in depth in my inner child healing work, because so much of what we call anxiety, low self-esteem, and emotional dysregulation in adults has its roots in these early experiences.

Can hypnosis erase memories?

Can Hypnosis Remove Bad Memories?

The short answer is no. And, even if it were possible, erasing memories would not be ethical.

Bad memories serve a purpose. They are part of how you learned to navigate the world and protect yourself. Removing them entirely would be like deleting the safety information from a manual you might still need.

Research into hypnosis and memory, published in Frontiers in Psychology in 2025, confirms that while hypnosis can influence how memories are experienced and reconsolidated, it cannot and does not simply delete stored information. The same research also highlights an important caution: hypnotic regression aimed at “recovering” hidden memories carries real risks of generating false memories, which is why this is not a legitimate therapeutic use of the technique.

What hypnosis can do, what makes it such a powerful therapeutic tool is remove the overwhelming emotional charge from bad memories, so that you retain the information without being controlled by the distress.

There is a crucial difference between remembering that something happened and being flooded with the terror and helplessness of living through it again. Hypnotherapy targets that difference.


How Hypnosis Interacts With the Brain’s Memory Systems

Hypnosis works because it changes your relationship with your own internal experience. In a hypnotic state, the analytical, critical mind becomes quieter, and it is widely accepted that the subconscious, where emotional patterns and memories are stored, becomes more accessible.

This is not magic. It is neurological.

Research published in PubMed has shown that hypnosis selectively reduces activity in the frontal lobe, which governs explicit attentional processing, while boosting activity in the striatum, associated with more automatic, procedural forms of learning. This shift in brain state is what makes hypnosis particularly well suited to working with material that exists below the level of conscious awareness.

The key neurological concept here is memory reconsolidation. Every time a memory is recalled, it briefly becomes malleable before being re-stored. Your memories can be changed depending on your emotional state when you remember them. A systematic review and meta-analysis published in Translational Psychiatry by Astill Wright and colleagues found a large effect of reconsolidation-based interventions in the treatment of PTSD, concluding they represent a genuinely promising avenue for trauma treatment. Hypnotherapy takes advantage of this window, allowing the emotional content of a memory to be altered without erasing the factual content.


Processing Trauma Without Reliving It

One of the most effective hypnotherapy approaches for traumatic memories is the Rewind Technique, which uses what researchers call Visual-Kinesthetic Dissociation.

Rather than being immersed in a traumatic memory and experiencing it through your own eyes as though it is happening right now, the Rewind Technique guides you to observe the memory from a safe, external perspective. You become a calm witness to the event, rather than a helpless participant in it.

This distinction is neurologically significant. When you observe a memory from a dissociated perspective while your body is physically relaxed, your brain receives contradictory signals. The memory is active, but you are not in danger. This mismatch is precisely what allows the memory to be rerouted, moved from the amygdala’s alarm system into the hippocampus’s historical archive, where it belongs.

A randomised controlled trial published in PubMed (PMC11921860), conducted by Astill Wright and colleagues at Cardiff University School of Medicine, found that the Rewind Technique produced a 12.64-point reduction in PTSD symptoms compared to a waitlist control group, with a large effect size comparable to traditional trauma-focused therapies, but requiring only 1 to 3 sessions rather than 12 to 20. Ten out of twenty participants who received the technique no longer met the diagnostic criteria for PTSD after treatment.

Further supporting this approach, a randomised controlled trial of 74 male veterans published in Psychotherapy Research found that 71% lost their DSM diagnosis for PTSD following the Reconsolidation of Traumatic Memories protocol — a closely related approach — with effect sizes ranging from 1.45 to 2.3. Results were stable at one-year follow-up.

You can explore the neuroscience and research in much greater detail in my post on hypnotherapy for PTSD and the Rewind Technique.

I also have a popular guided recording of this technique, it can be found below. Many people find they can experience significant relief simply from working through it at home.

What Happens in the Brain After the Emotional Charge Is Removed

Once the negative emotion has been separated from the traumatic memory, the real work of rebuilding can begin.

One of the most important things hypnotherapy can then do is help you rehearse the future. Because the mind cannot fully distinguish between a vividly imagined experience and a real one, guided visualisation creates genuine neural pathways.

Cognitive neuroscience research has confirmed that mental rehearsal activates the same brain regions as physical practice. When you close your eyes and clearly imagine yourself moving through a situation that once triggered you calmly, confidently, without fear your brain begins to lay down the neural architecture of that new response. A meta-analysis of mental practice research found that individuals who visualised the process of achieving a goal showed improved performance, greater confidence, and reduced stress compared to those who did not use mental rehearsal. The more you rehearse, the stronger those pathways become.

This is why hypnotherapy is not merely about resolving the past. It is about building the future.


Hypnosis for Different Types of Memory-Related Challenges

Trauma and PTSD

Traumatic memories are perhaps the most obvious application. Whether the trauma occurred in childhood or adulthood, the Rewind Technique and related approaches can help move those memories from active threat to quiet history.

For survivors of childhood trauma especially, memories are often fragmented and pre-verbal stored as physical sensations, emotional states, and body responses rather than clear narrative recollections. Hypnotherapy is uniquely well-suited to this work because it does not require you to articulate what happened. The nervous system can begin to update even when the words are not there. A case study published in Cureus found that a memory reconsolidation-based protocol produced significant reductions in complex PTSD symptoms in a patient with a history of prolonged childhood trauma, without requiring detailed verbal disclosure.

Phobias

Many phobias are rooted in a single encoding event, one moment where the brain decided that a particular stimulus was dangerous. The memory of that original event, even when it is not consciously accessible, continues to drive the phobic response. Hypnotherapy can identify and desensitise the original memory, removing the learned fear response at its source rather than managing its surface symptoms.

Anxiety and Flashbacks

Anxiety is often the body’s response to anticipated danger and for people with traumatic histories, that sense of danger is constantly being triggered by present-day reminders of past experiences. Smells, sounds, tones of voice, certain interpersonal dynamics. These can all set off an alarm response the conscious mind cannot override.

A 2025 neuroimaging study in Depression and Anxiety examining nearly 2,000 patients with anxiety disorders found that greater negativity bias (the tendency to over-weight threatening information) was linked to measurable dysfunction in the frontal, temporal, and parietal lobes, regions critical for cognitive control and emotional regulation. By addressing the underlying memories and their emotional charge, hypnotherapy can work at precisely the level where this dysfunction originates.

Emotional Flashbacks and Toxic Shame

Emotional flashbacks are a particularly insidious form of trauma response. Unlike visual flashbacks, which involve reliving a specific scene, emotional flashbacks involve being suddenly flooded with the feelings of the original trauma. The helplessness, the worthlessness, the terror without a clear trigger or memory attached.

This is especially common for adults who grew up in dysfunctional families, where the trauma was not a single event but a sustained environment of emotional unpredictability, criticism, or neglect.

Hypnotherapy and inner child work can address these patterns at a deep level, helping you connect with the parts of yourself that internalised those early experiences and offering them the safety, acceptance, and love they never received. This is the heart of my Inner Child Healing Sessions.

What Hypnosis Cannot Do With Memory

It is worth being clear about the limits, because there are common misconceptions worth addressing directly.

Hypnosis cannot reliably recover repressed memories. Research published in Frontiers in Psychology confirms that hypnotic regression and guided imagery carry a significant risk of generating false memories — recollections that feel completely real but are confabulated. The same research notes that hypnosis can increase the production of incorrect recall among hypnotisable individuals, making it an unreliable and ethically problematic tool for memory retrieval.

Hypnosis cannot erase memories entirely. The goal is always integration, making peace with what happened, not deletion. Attempting to wipe a memory would also remove the information your nervous system encoded for your own protection.

And hypnosis is not a magic fix. It is a powerful tool, but its effectiveness depends on the skill of the practitioner, the readiness of the client, and the nature of what is being worked on. Lasting transformation often involves a combination of hypnotherapy, inner child work, and the gradual development of new emotional habits and relationships.


Frequently Asked Questions About Hypnosis and Memory

Will I remember what happens during hypnosis?

Most people remember everything. Hypnosis is not unconsciousness. It is more like a deeply focused state of relaxed attention. Some people find that details drift away afterwards, much as dream memories fade after waking, but amnesia during hypnosis is rare and not necessary for the technique to work.

Can hypnosis create false memories?

This is a legitimate concern. Research confirms that poorly conducted hypnotic regression can lead to false memory formation. A well-trained hypnotherapist will never use leading questions or suggestions designed to uncover hidden memories. Reputable hypnotherapy focuses on changing your relationship with memories you already have, not implanting or excavating new ones.

How many sessions will I need?

This varies depending on what you are working on. The Rewind Technique for PTSD often produces substantial results in 1 to 3 sessions, as the Cardiff University RCT found. Deeper patterns rooted in childhood, such as those addressed in inner child work typically benefit from a more extended programme.

Is online hypnotherapy as effective as in-person?

In my experience, yes. Many of my clients work with me entirely online, and the results are fully comparable. The hypnotic state does not require physical proximity. It requires trust, intention, and a safe, quiet space, all of which are achievable over video.

What if I have tried therapy before and it did not work?

This is something I hear regularly. Many people have spent years in traditional talking therapy and gained insight without gaining relief. This makes complete neurological sense. Talking therapy primarily engages the prefrontal cortex, but traumatic memories are stored in the limbic system and the body, not in the thinking mind. Hypnotherapy works at a different level, which is why it can succeed where purely verbal approaches have not.


A Note on the Courage It Takes to Begin

If you are reading this, you have probably been carrying something heavy for a long time. Perhaps you have managed it, coped with it, worked around it. Perhaps you have tried to talk about it and found that talking only scraped the wound.

The idea that the brain can genuinely update, that the nervous system can learn, at a deep level, that the danger has passed can feel almost too good to be true. But this is what the science shows. Memory reconsolidation is real. The brain remains plastic throughout life. The stories we carry do not have to remain as vivid and urgent as the day they were written.

If you would like to explore how hypnotherapy might help you, I offer a free initial consultation call. You do not need to share your story in detail. We can simply talk about where you are, what you have tried, and whether this approach feels right for you.

You can also begin with my guided Rewind Technique recording, available as an MP3 download, which allows you to experience the process privately, at your own pace, in your own home.


Summary

Hypnosis works with the brain’s natural memory reconsolidation process to update the emotional charge of traumatic memories. The Rewind Technique allows trauma to be processed without requiring verbal disclosure or re-experiencing painful events. Once the negative emotion is removed from a memory, guided visualisation can build new neural pathways, rehearsing calm, confident responses to situations that once triggered fear.

Hypnotherapy is highly effective for PTSD, phobias, anxiety, emotional flashbacks, and the deep wounds left by childhood dysfunction. It cannot and should not be used to erase memories or uncover repressed ones. The goal is always integration, becoming someone for whom the past is genuinely the past.
