Many people experiencing anxiety describe a deeply unsettling sensation: feeling detached from themselves or as though the world around them is not fully real. This can be frightening, especially when it happens for the first time.
These experiences are known clinically as depersonalisation (feeling disconnected from oneself) and derealisation (feeling detached from one’s surroundings). Although distressing, they are recognised responses within the anxiety and stress spectrum.
From a counselling perspective, these experiences are not signs of “losing your mind.” They are typically protective responses from an overloaded nervous system.
What Depersonalisation and Derealisation Feel Like
People often struggle to describe these experiences clearly, but common descriptions include:
Depersonalisation (feeling detached from self)
Feeling like you are observing yourself from outside
Emotional numbness or reduced emotional intensity
Feeling disconnected from your body or thoughts
A sense of being “on autopilot”
Derealisation (feeling detached from surroundings)
The world feeling dreamlike or foggy
Objects or people seeming unreal or distant
Distorted sense of time
Feeling as though you are “not fully here”
These experiences can last seconds, minutes, or longer, and often fluctuate with anxiety levels.
Can Anxiety Cause These Feelings?
Yes. Anxiety is one of the most common triggers for both depersonalisation and derealisation.
When the nervous system becomes highly activated, the body enters a survival state known as the fight, flight, or freeze response. If this activation becomes overwhelming or prolonged, the brain may shift into a protective “disconnect” mode.
This is not a malfunction. It is a protective mechanism designed to reduce emotional overload.
The Neuroscience Behind Feeling Unreal
From a neuroscience perspective, depersonalisation and derealisation are linked to changes in how the brain processes threat, emotion, and awareness.
Key systems involved include:
1. The limbic system (emotional threat response)
When anxiety is high, the limbic system becomes overactivated, signalling danger even when none is present.
2. The prefrontal cortex (thinking and control)
The brain may attempt to regulate overwhelming emotion by reducing emotional engagement and shifting into a more detached cognitive state.
3. Perceptual processing networks
Under stress, sensory processing can become altered, affecting how the brain integrates sight, sound, and bodily awareness.
Together, these changes can create a sense of disconnection from both self and environment.
Why the Brain Creates “Distance”
Depersonalisation and derealisation are often understood as protective adaptations.
When emotional intensity becomes too high, the brain may reduce sensory and emotional processing to prevent overload. This can feel like:
Emotional “numbing”
Mental fog
Observing life rather than feeling fully inside it
Although uncomfortable, this is often the brain’s attempt to protect you from feeling overwhelmed.
The Anxiety–Detachment Cycle
These experiences can become more distressing when interpreted as dangerous. A common cycle looks like this:
Anxiety activation → detachment sensations → fear of losing control → increased anxiety → stronger detachment
For many people, the fear of the experience itself becomes part of what maintains it.
From a therapeutic perspective, breaking this cycle often involves reducing fear of the sensations rather than trying to eliminate them immediately.
Common Triggers
Depersonalisation and derealisation can be triggered by:
High levels of anxiety or panic
Chronic stress or burnout
Sleep deprivation
Emotional overwhelm
Trauma or unresolved distress
Prolonged periods of hypervigilance
It can also occur during panic attacks, where the nervous system is rapidly activated.
Is It Dangerous?
Although these experiences feel alarming, they are not considered dangerous in themselves.
They do not indicate:
Psychosis
Brain damage
“Going crazy”
Loss of control
Instead, they are understood as temporary dissociative responses linked to stress and anxiety regulation.
However, because they feel so unusual, they often increase fear, which can prolong the experience.
Why It Feels So Convincing
One of the most challenging aspects is how real the experience feels.
This is because:
The brain is altering perception of reality
Emotional processing is reduced
Attention becomes internally focused
The body remains in a stress response state
The combination of these factors creates a powerful subjective experience of unreality, even though external reality has not changed.
How Long Does It Last?
The duration varies widely.
For some people, it may last:
Seconds during a spike in anxiety
Minutes during panic
Longer periods during chronic stress or burnout
Importantly, it tends to fluctuate and often reduces when the nervous system settles.
What Helps in the Moment
The goal is not to force the experience away, but to help the nervous system return to regulation.
1. Grounding through the senses
Name five things you can see
Feel your feet on the floor
Notice textures or temperature around you
2. Gentle orientation
Remind the brain of safety:
“I am here, in this moment”
“This is anxiety-related and will pass”
3. Reduce internal checking
Constantly scanning “Do I feel real yet?” can maintain the cycle. Allowing the sensation to be present without monitoring it often helps it settle more quickly.
Therapeutic Understanding: What Counselling Focuses On
In therapy, work often involves:
Understanding how anxiety affects perception and awareness
Reducing fear of dissociative symptoms
Processing underlying stress or trauma if present
Strengthening emotional regulation and grounding skills
Rebuilding a sense of safety in the body
Approaches such as CBT, trauma-informed therapy, and somatic approaches can all be helpful depending on individual needs.
When to Seek Support
It may be helpful to seek professional support if:
Feelings of unreality are frequent or distressing
Anxiety is ongoing or escalating
Panic attacks are occurring
Daily functioning is affected
There is fear of losing control or “going mad”
Support can help reduce both the symptoms and the fear response that often maintains them.
Final Reflection
Feeling detached or unreal during anxiety can be deeply unsettling, but it is a recognised response of an overactivated nervous system rather than a sign of losing touch with reality.
Depersonalisation and derealisation are often the brain’s way of protecting itself from emotional overload.
With understanding, support, and therapeutic work, these experiences usually become less frequent and less intense, as the nervous system learns to feel safe again in the present moment.
