Can Anxiety Cause a Feeling of Unreality?

Yes, anxiety can cause feelings of unreality through a symptom called derealization. This occurs when anxiety activates your body's fight-or-flight response, altering brain chemistry and perception. Studies show that up to 74% of people with anxiety disorders experience some form of derealization. During these episodes, the world may feel dreamlike, foggy, or as if you're watching life through a film. Your surroundings might seem distant, artificial, or two-dimensional. This happens because stress hormones like cortisol affect areas of the brain responsible for processing reality and spatial awareness. While distressing, these feelings are temporary and not dangerous. The sensation typically fades as anxiety levels decrease through relaxation techniques, deep breathing, or grounding exercises.
