On 3 July，2003，a 35-year-old Englishman called Doug Bruce walked into a police station in New York，and told the police that he did not know his own name.He had woken up a few minutes earlier on a subway train，with a headache，and had no idea where he was going or who he was."I was frightened，"he said later，when talking about the experience."I didn't know anything.It was like being in the darkness."
    Doug went to the police station because he had nowhere else to go.He was wearing a T-shirt，shorts and had a bag with something in it：a Spanish book，a bunch of keys and a map of New York.The police were confused（困惑的）."We'd never had anything like this before，"said a policeman.They sent Doug to a hospital.On his name card the nurse wrote"unknown white man".
    The doctors were surprised at his memory loss.Although Doug could make sentences without difficulty，he remembered nothing about his own past.One doctor at the hospital said that he had only ever seen such a serious disease"in the movies and books".
    The hospital would not let Doug go until he had come to himself.Finally，hospital staff found a phone number in his Spanish book.It was the number of his friend.Doug phoned and she recognized his voice at once."Is that you，Doug？"she said.His friend went to the hospital，told the doctors who Doug was，and took him home.
    "Home"turned out to be a perfect flat in downtown Manhattan，which he shared with two dogs and three birds.Doug discovered that he had once lived in Paris，where he had made a lot of money working at a big company.Then he had got tired of the business world，and so he left and went to New York for a four-year course in photography.
    Since Doug had discovered himself，he had to deal with other difficulties.He was worried about meeting his family and friends.They seemed like strangers to him.His sisters told him that he had changed.Before his memory loss，he seldom showed his feelings in public.Now he has become much more relaxed and doesn't fear showing his feelings.
