We survived the 2012 Mayan doomsday prophecy and now it seems Jean Dixon has warned that the world will end this year. Who is Jean Dixon, I hear you all ask. She was formerly an advisor to US Presidents and correctly predicted the assassination of John F Kennedy. She was one of the most famous self-proclaimed psychics and astrologers in America. She wrote seven best-selling books, including an autobiography filled with her predictions and a horoscope novel for dogs. Chillingly, seven years before the death of JFK, who was shot as he travelled in a motorcade through the heart of Dallas, she predicted he would be assassinated.
