This video has surfaced recently of an apparent granny ghost in an elevator, captured by an office building's CCTV system in Singapore. At first, it was described as happening in the Volkswagen office tower in Shanghai, China ... prompting officials there to say it wasn't recorded in their offices. Then, it became known as the Raffles Place ghost in Singapore. Anyway, it's been deemed to either be authentic, or a pretty good CGI attempt.
