Reincarnation of Sai Baba
A neighbor of mine claims that she has met the reincarnation of Sai Baba. Apparently before Sai Baba died he left 3 of his possessions with a close disciple and promised that he would return for them some day. The disciple died, passed it on to his son who in turn passed it on to his son (each son was told to keep it a secret). One day a doctor who used to visit them asked them for the same items and told them where they kept the things. The doctor has now become revered as a reincarnation of the saint and has gathered a fairly large following in Bombay. Apparently his weekly talks gather about 40,000 people and he has been performing miracles.

Coincidentally, the method by which new Dalai Lamas are found is similar - the old Dalai Lama before his death leaves clues and possessions behind and then his priests present any Dalai Lama hopefuls with a choice of articles and they have to pick the right ones. Guess thats the only way to prove you were actually that person...
