Quick Answer: Dissociative disorders are health conditions where a person feels disconnected from their thoughts, feelings, identity or surroundings. There are three types: depersonalization disorder, derealization disorder and dissociative identity disorder (DID). These are classified in the DSM-5. It usually develops as a response to trauma. If dissociation affects your life, relationships or sense of self it’s time to seek help.
Most people who experience dissociation for the time think something physical is wrong with them like a brain problem or extreme tiredness. They don’t think “I have a health condition.” The disconnection feels strange and sensory not like an issue.
That’s what makes dissociative disorders so confusing: the symptoms don’t look like what most people imagine as a health struggle.
This article explains what dissociation feels like breaks down the three dissociative disorders and gives you signs that you need professional treatment.
What Dissociation Actually Feels Like
Dissociation is when your normal feelings of self, memories and experiences get disrupted. Here’s what it can feel like.
Depersonalization, one of the common dissociative experiences feels like you’re watching yourself from outside your body. You’re doing things like talking, driving or eating. It feels like there’s a barrier between you and the experience. Your hands look like they belong to someone. Your voice sounds away. You know you’re real. It doesn’t feel like it.
Derealization is the opposite. The world around you feels unreal. Rooms look flat like sets on a stage. Familiar people look like strangers wearing faces. Colors seem dull. Sounds are muffled like you’re listening from underwater. A 2019 review found that depersonalization and derealization often happen together.
It’s worth noting that brief depersonalization is common. It can happen to anyone after a lack of sleep during a fever or, after a strong emotional shock. That’s not a disorder. A disorder is when these experiences happen often for a long time and start affecting your daily life, relationships or sense of self.
The Three Main Dissociative Disorders (And How They Differ)
| Disorder | Core Experience | How It Differs |
| Depersonalization/Derealization Disorder | Persistent feeling of being unreal or observing yourself from outside | The person stays oriented in reality – they know it’s a perception, not a fact |
| Dissociative Amnesia | Memory gaps that can’t be explained by ordinary forgetting | Often follows acute trauma; can involve fugue states where a person travels and can’t account for time |
| Dissociative Identity Disorder (DID) | Two or more distinct personality states that alternately take control | Previously called multiple personality disorder; involves identity fragmentation, not psychosis |
Dissociative Identity Disorder is often misunderstood. It is not like what you see in movies. Dissociative Identity Disorder is a condition that develops in people who experienced trauma when they were children before they were nine years old. This is what Dr. Onno van der Hart found out. He is a person who worked on the structural dissociation theory of trauma. The different identities in Dissociative Identity Disorder are not random characters. They are parts of a person’s personality that formed because of the trauma they experienced.
The Connection to Trauma Nobody Explains Clearly
Most people do not understand disorders. They think it is like a glitch in the brain. That is not true. Dissociation is what the brain does when it is under a lot of stress. It helps the person survive by separating their experiences. Dr. Bessel van der Kolk is a psychiatrist who wrote a book called The Body Keeps the Score. He says that dissociation is like the brain stepping of a moment that is too much to handle. This can be helpful in a crisis. It can also be a problem if it happens when there is no danger.
Dissociative disorders are often connected to Post Traumatic Stress Disorder and complex trauma. Complex trauma is when someone experiences trauma over and again like abuse. Many people with Dissociative Identity Disorder have experienced trauma. Dr. Stephen Porges is a neuroscientist who developed the theory. He says that when we experience trauma our nervous system can freeze or shut down. This can cause us to feel detached or numb which is what happens in dissociation.
When Dissociation Becomes a Problem
Dissociation can be a problem that needs to be treated. This can happen when:
- Dissociation lasts for hours or days
- You lose time. Cannot remember what happened
- You do things that you do not remember
- You feel like you are watching your life of living it
- Your relationships suffer because you “check out” or go else
- You use substances to cope with feeling unreal
Using substances to cope with dissociation is not an idea. It may seem like it helps. It can actually make things worse. If you recognize yourself in these examples you should talk to a health professional. They can help you figure out what to do.
What Treatment for Dissociative Disorders Actually Involves
Treatment for dissociative disorders is not just talking about your memories. It is about working with your system and memory to process traumatic experiences.
One type of therapy that is helpful is called EMDR. It was developed by Dr. Francine Shapiro. Uses special movements to help the brain process traumatic memories. Another type of therapy is trauma-informed CBT. It helps people recognize what triggers dissociation and build skills to cope with it.
For people who are struggling with dissociation an Intensive Outpatient Program can be helpful. It provides therapy sessions to help people make progress.
At Waterview Behavioral Health we work with adults who are experiencing dissociation. We help them work through their trauma and develop skills to cope with dissociation. Dissociative Identity Disorder is a condition that needs to be treated with care and understanding. It is not something to be ashamed of. It is not something that you have to deal with alone.
Frequently Asked Questions
A dissociative disorder is a mental health condition characterized by disruptions in consciousness, memory, identity, or perception. The three main types – depersonalization/derealization disorder, dissociative amnesia, and dissociative identity disorder – are all classified in the DSM-5 and typically develop following trauma.
No – and the distinction matters clinically. In dissociation, the person knows their perception is altered; they feel unreal but know they are real. In psychosis, reality testing breaks down and the person can’t distinguish between what’s real and what isn’t. EMDR and trauma therapy are used for dissociation; they’re not first-line treatments for psychosis.
Yes. Dissociation frequently occurs alongside anxiety disorders, particularly panic disorder and PTSD. During a panic attack, depersonalization and derealization are common – the nervous system’s overactivation produces the same shutdown response as trauma. This is why the two conditions often need to be treated together.
Research estimates DID affects approximately 1-3% of the general population – similar in prevalence to OCD. It’s underdiagnosed largely because clinicians receive limited training in dissociative disorders, and because people with DID often present primarily with depression or anxiety rather than identity disruption.
Weekly therapy is appropriate when dissociation is mild to moderate and doesn’t significantly affect daily functioning. An IOP makes more sense when dissociation is frequent, involves memory gaps, disrupts work or relationships, or co-occurs with substance use or a mood disorder. A structured program provides the regularity and clinical support that trauma this embedded typically requires.
