In which disorder would a person be likely to experience wandering with amnesia regarding their personal history?

Dissociative fugue is characterized by a sudden, unexpected temporary loss of personal identity and the ability to recall one's past, often accompanied by wandering. Individuals with this disorder may find themselves in locations far from where they typically reside, unable to remember significant personal information that could help establish their identity or personal history.

This disconnection from personal history occurs due to a dissociative mechanism that protects the individual from emotional distress, which can arise from traumatic experiences or stressors. Thus, the experience of wandering coupled with amnesia specifically points to dissociative fugue as it embodies the essence of losing one's sense of self and memory about previous life experiences.
