"The key feature of dissociative fugue is "sudden, unexpected travel away from home or one's customary place of daily activities, with inability to recall some or all of one's past," according to the APA. The travels associated with the condition can last for a few hours or as long as several months. Some individuals have traveled thousands of miles from home while in a state of dissociative fugue."
