The syndrome of subjective doubles is a rare delusional misidentification syndrome in which a person experiences the delusion that he or she has a double or Doppelgänger with the same appearance, but usually with different character traits, that is leading a life of its own.[1][2] The syndrome is also called the syndrome of doubles of the self,[3] delusion of subjective doubles,[1] or simply subjective doubles.[4] Sometimes, the patient is under the impression that there is more than one double.[1] A double may be projected onto any person, from a stranger to a family member.[4]
