Hannah Upp hasdissociative fugue, an extremely rare form of amnesia, in which people lose access to their autobiographical memory and personal identity. Because of her condition, Upp occassionally goes missing for a few days or even weeks without warning.

During an episode of fugue, she is at loss of a sense of self. Without a coherent self-identity and collection of memories from the past, she becomes a different person from the Hannah Upp that her friends, family, and herself know her as.

She was once found laying face down in the waters of New York Harbor after going missing for three weeks. After being found and taken care of, she was able to restore her idenity as Hannah Upp, a 23 year old Spanish teacher, but could not recall her spontaneous travels. The three weeks felt like mere minutes for her.

The case of Hannah Upp brings up profound questions about self-identity or the lack thereof. If we associate autobiographical memory with personhood, is the Hannah Upp during an episode of fugue a different person from the Hanna Upp who is conscious of herself? If she were to commit a crime during one of her episodes, could we hold her accountable after the episode, even though she does not recall any of it?
