How Trauma Changes Your Brain and Beliefs (And How Hypnotherapy Can Help Heal it)

Trauma is more than a stressful experience. It changes your brain and alters your beliefs.

Two people can experience the same event. One person feels shaken but moves on. The other develops anxiety, seems to become hypervigilant, and experiences intrusive flashbacks of the experience.

Why?

Because trauma isn’t about what happened to you, it’s about what happened within you as a result of what happened to you.

As bestselling author, Gabor Mate describes it, trauma is not the event that inflicted the wound. Trauma is the wound that you sustained as a result. It’s the lasting effects of the experiences.

Trauma changes the way we relate to ourselves and the world at large. These are tangible changes. New neural pathways are created in the brain, causing new associations and new beliefs. This is how trauma changes the brain.

But with the discovery of neuroplasticity, we know that these changes are not permanent. Our brain continues to have the ability to create new neural pathways, creating new associations and new beliefs all throughout our lives.

This means that even the patterns that were created as the result of trauma can be unlearned. But to understand how to heal, we first need to understand what trauma is and how it has impacted us.

What Trauma Actually Is (And What It Isn’t)

Trauma Is a Nervous System Response

Trauma is not defined by the event. This means it isn’t the abuse, the illness, the accident or the loss. It is the effects of that experience that still live inside you after the experience has ended.

When we experience a highly distressing event, our body responds. Our nervous system and limbic system are our body’s threat detection systems. They help us discern threat from safety.

Trauma is an event that overwhelmed our system. An event that caused powerlessness, collapse, or an overwhelming sense of threat. It’s as if the nervous system and limbic system couldn’t handle the emotional title wave and caused real changes to the way these systems operate.

In those moments of overwhelm, the subconscious mind is also rewiring. The danger and overwhelm that the nervous system is experiencing is causing new associations in the brain.

This is essentially our brain learning something new and creating new neural pathways so that it is remembered in future times.

We do this all the time. When you learned to tie your shoe, you were creating new neural pathways, and each time you practiced, those pathways became stronger.

Or if you were to put your finger over a candle flame, the heat of the flame causes pain, and you pull your and away. Just that one event is enough to create a strong neural pathway that helps you remember the pain and avoid causing it again.

We can categorize traumas into Big "T" and little "t" traumas in much the same way.

Big "T" and Little "t" Traumas

Big "T" traumas would be similar to the candle flame example. They are experiences with a bigger emotional impact, where your brain creates new neural pathways from one event alone.

Big "T" traumas could be:

• Abuse

• Sudden Loss

• Medical Trauma

• Accidents

• Assaults

Whereas little "t" traumas are less intense experiences, but through repetition, still create the same neural changes in the brain, like the example of learning to tie your shoe.

After a few repetitions, you forever know how to tie your shoe because those neural pathways have been created and strengthened. Just like repetitive experiences that left you feeling unsafe can cause you to carry forward that learned anxiety or fear.

Little "t" traumas could be:

• Emotional neglect

• Being shamed repeatedly

• Chronic criticism

• Growing up walking on eggshells

• Feeling unseen or unheard

How Trauma Changes Your Perception of Yourself and the World

The reason trauma has such a massive impact on us is because what we “learn” from trauma changes our perception of ourselves, others, and the world through the lens of our traumatic experience.

Trauma Changes How You See Yourself

Trauma can have a major impact on how we perceive ourselves, leading to limiting and negative beliefs about who we are and what we are capable of.

Common beliefs could sound like:

• I'm "bad"

• I’m not safe.

• I’m too much.

• I’m not enough.

• I have to earn love.

• I have to stay small.

• I can’t trust myself.

We start to detach from our authentic self and see ourselves through the lens of our trauma. Beliefs formed during heightened emotional states become deeply embedded in the subconscious mind.

Trauma Changes How You See Others and the World

Trauma often changes the way we perceive others and the world at large.

As we create new beliefs through the lens of the trauma, we might create beliefs like:

• People leave.

• Authority figures aren’t safe.

• Conflict is dangerous.

• The world is unpredictable.

• There isn’t enough to go around.

• Everybody is judging me.

These beliefs impact all areas of life, from our relationships to our finances and even our state of mind.

Tangible effects could look like:

• Relationship turmoil

• General, chronic anxiety

• Lacking boundaries

• Unhealthy attachment styles

• Difficulties in career advancement

• Addictions or Disorders

How Trauma Affects the Brain and Nervous System

Our brain will always prioritize survival over everything else. It’s a response built right into the most primal part of our brain.

During a threat, our emotional brain will override logic and reason, and we simply react out of survival. This then becomes a learned response that is stored in the nervous system and subconscious mind.

This is why you might experience “triggers” related to trauma. For example, if you experienced physical abuse from a caregiver, you might feel overwhelmed, shutdown, afraid or even angry when a partner raises their voice in an argument.

That learned emotional survival instinct has become triggered, and your emotional brain overrides logic and you simply react to the perceived threat. It’s an emotional pattern of survival and protection that has been learned and is stored in the mind.

Trauma Lives in the Subconscious Mind

Trauma is stored as emotion, sensation and belief. The often are not logical because in times of trauma, the emotional mind overrides logic.

In the above example, logically you might know that your partner raising their voice in an argument isn’t a real threat, but because the trauma of abuse has been stored in your subconscious, your emotional mind overrides logic and you react with overwhelming emotion.

Because these patterns are often not logical, it can be difficult to move through them with talk therapy and logic. The real change happens when we move to the same level of mind where these patterns exist, the subconscious.

Healing Trauma with Hypnotherapy

Hypnotherapy is one way we access that deeper level of mind and can resolve the learned patterns and associations from trauma directly.

Hypnotherapy is a deepened state of awareness where our mind is more open to new ways of thinking. This opens the door to making changes on a deep emotional and belief level much easier and more efficient.

Your Brain Is Neuroplastic — Which Means Trauma Is Not Permanent

The changes trauma created in your brain and nervous system are not a life sentence.

Because your brain is neuroplastic, meaning it is capable of rewiring and reorganizing itself at any age. This helps us understand why the patterns formed in survival can be reshaped in safety.

Trauma wires the brain through intense emotion and perceived threat.

Healing happens when we access those same subconscious pathways and update them with new meaning, new perspective, and a felt sense of safety.

This is why hypnotherapy for trauma can be so powerful.

Rather than trying to override old survival patterns with logic alone, hypnotherapy works at the deeper, subconscious level where those beliefs and emotional imprints were formed.

From there, we can shift neural pathways more effectively and allow the nervous system to finally stand down.

Healing trauma isn’t about erasing your past.

It’s about changing how your brain and body hold it.

In the next post, we’ll explore why trauma shows up as triggers and intrusive memories, and how accessing them at the subconscious level allows them to finally resolve.
