Derealization is a psychological phenomenon where a person feels detached from their surroundings, as if the world around them is unreal or dreamlike. This experience can make familiar places and people seem strange or distorted, leading to feelings of confusion and anxiety. It often occurs in response to stress, trauma, or certain mental health conditions, such as anxiety disorders or depression. During episodes of derealization, individuals may experience visual distortions, a sense of time distortion, or a feeling of being an observer in their own life. While it can be unsettling, derealization is generally not harmful and can be temporary. Treatment may involve therapy or coping strategies to manage underlying stressors.
