You’ve probably heard of “phantom limb” syndrome, or even the bizarre “idle hand” disorder, a neurological disorder where one’s hand may seem to act independently of it’s owner. However, what about “Supernatural Phantom Limb” disorder? According tothe Swiss news source, a 64-year-old woman now reports to doctors at a hospital in Geneva that a “milky white” third arm exists, which she is able to “manifest” to perform tasks like scratch itches on various parts of her body.

Doctors who have examined the patient call this “the first case known to doctors of a person being able to feel, see and deliberately move a limb that doesn’t exist.” But how are they sure that, at least to the patient, the limb does indeed exist?
