Let's look at a case from psychiatrist Mashm in 1961:

Bonice is a 42-year-old housewife. She was brought in for treatment because she suddenly disappeared four years ago, but was recently found. At that time, she was in a small town more than a thousand kilometers away. When her family found her, she denied knowing her husband and children, or that her name was Bonice. She claimed that her name was Rose, the name of a girlfriend she admired most....

In the eyes of ordinary people, fugue is sleepwalking, but there is actually a difference between the two.

The role that the sleepwalker performs during his sleepwalking is still himself, and it lasts for a short period of time, at most one night. However, the dreamer does not. He completely lives the life of another role, which lasts for a long period, ranging from a few days to a long period of time. Years can be said to be a dream of life.

There are also differences between psychogenic fugue and psychogenic amnesia. The main difference is that the personality of the patient is completely changed when the fugue disorder occurs, while the personality of the patient with amnesia does not change, but just forgets what he has done.

The difference between fugue disorder and multiple personalities is that patients with multiple personalities change their personality but their living place remains the same. Patients with fugue disorder travel abroad, and their personality remains relatively stable during travel. Once they wake up from the fugue state, they completely restore their original personality.
