A fugue state (also known as a 'psychogenic fugue' or 'dissociative fugue') describes a state of mind where a person experiences a break in identity and attempts to run away from some perceived threat, usually something abstract such as the person's identity. People who enter into a fugue state may disappear, running away to a completely different geographical region and assuming another identity. A bewildered facial expression is a common symptom of the condition that can involve both physical and psychological escape from a stressful environment.
