From Japan Times Online:
Take this account, related by a sales clerk at a Tokyo mall.
“It was about 8 p.m., and I was powdering my nose in the ladies room,” she tells Spa! “I saw a man’s face reflected in the mirror; but when I whirled around, nobody was there. When store security checked the security video, no one else was in it except me! But I was absolutely certain I’d seen him: He was in his late 20s and not bad looking, but had a kind of greenish pallor and his hair was a mess.
“Then, about three weeks later, our store apprehended a shoplifter, who I recognized as the guy who I’d seen in the mirror! He was taken to the police station and they contacted his father. I said to the father, ‘Your son had been in our store not long before,’ but the man insisted that was impossible. ‘My son has been institutionalized, and this is the first time in three months he’s been allowed out.’ “
“In front of the police station the father went to flag a taxi, and the son spoke to me for the first time. ‘It was nice seeing you again,’ he said, with this weird smile. It gave me such a shock I was afraid to be alone for a while after that.”
