Why Does Everything Feel Unreal? Understanding Derealization

What is derealization?

Derealization is a mental state where the world around you feels distorted, distant or unreal. People and objects may seem like they're not actually there, or you may have the sense of moving through a fog, with something separating you from your surroundings.

Most people experience derealization at least once — it arrives and passes. For others, episodes can last for hours or even months. It's different from depersonalization, which is when you feel disconnected from your own physical body, often as though you're floating outside of or above yourself. It's possible to experience both at the same time, and if they happen repeatedly together, that may indicate depersonalization-derealization disorder (DPDR).

What are the symptoms of derealization?

Symptoms vary and can fluctuate in intensity. Some people describe it as feeling like they're "going crazy," but recognizing that something feels different is actually a reassuring sign — when someone can no longer distinguish reality from imagination, that points to something else, like a psychotic disorder.

Derealization symptoms include:

• Feeling like the world is muted or fake
• People and things seeming blurry, fake, or the wrong size
• Sounds that feel too loud, too quiet, or distorted
• Time feeling like it's passing too fast, too slow, or standing still
• People around you feeling unreal, almost robotic, even when you know rationally they aren't
• A sense of a wall separating you from the world outside you

These overlap with symptoms of depersonalization-derealization disorder, a condition that can affect relationships, work and daily activities — though only an estimated 1–2% of the population develops the full disorder. Derealization most often shows up as a symptom of something else, including PTSD and complex PTSD, depression, panic disorder, dementia, schizophrenia, substance use disorder, and other dissociative disorders such as amnesia.

What causes derealization?

Trauma is the most common cause, especially trauma that happened at a young age — it can teach a person to detach from the world as a coping mechanism. Common sources include sexual or physical abuse, the sudden death of a loved one, witnessing domestic violence, having a relative with a severe mental health disorder, living through a natural disaster or conflict, and car accidents. Episodes can also be triggered indirectly, by everyday stressors like a difficult day at work or an argument in a relationship.

One NIMH-supported study of more than 1,400 people treated in emergency departments after a trauma found that roughly half reported symptoms of derealization two weeks afterward — and that group also showed greater PTSD and depression symptoms three months later. Overactivation in the brain regions that control emotion regulation may drive the sense of detachment after a traumatic event, while other regions involved in emotional experience may contribute to the distorted perceptions themselves.

Is there treatment for derealization?

Derealization is uncomfortable and can feel frightening, but it isn't life-threatening, and it can often be managed with breathing and grounding exercises. If episodes last for days, feel unbearable, or are increasing in frequency and intensity, it's worth seeking clinical help.

Structured programs like an intensive outpatient program (IOP) provide that level of care for derealization, trauma and related mental health challenges (what level of trauma care do I actually need? compares the options), integrating evidence-based therapies such as Cognitive Behavioral Therapy (CBT) and Internal Family Systems (IFS) to help process trauma, build self-awareness, and learn skills to manage symptoms going forward. There's no medication built specifically to treat derealization, but antidepressants, anti-anxiety medication and mood stabilizers, managed through medication management, can help ease symptoms when they're part of a broader picture. With treatment, symptoms and overall mental health in dissociative disorders have been repeatedly shown to improve.
