Dissociative Fugue, common in multiple personality: New York Times reports “9 Years Later, a Teacher Vanishes Again. This Time, in the Virgin Islands” (1).

Dissociative fugue is a temporary psychological symptom in which people have amnesia for who they are, and they travel to where people do not know them. It rarely occurs as a condition in and of itself, but it commonly occurs as a symptom of multiple personality (dissociative identity disorder) (2, p. 293).

The writers Agatha Christie and Sherwood Anderson had dissociative fugues, and so have a number of fictional characters: search “fugue” in this blog to see relevant past posts.
