Is it Halloween yet? Actress Koo Ji Sung sent shivers down her fans' spines when she revealed that she had a supernatural experience on the set of her latest movie, 'The Puppet'.

The encounter happened at dawn, she recalled. After days of filming, she claims she saw a young girl pass right by her dressing room mirror. Although she initially thought it was an actress playing a ghost, other cast members told her that the actress in question had never even appeared on set that day.

"I was very surprised at the time, but now I'm fine," she said. "People say that it's good luck to see a ghost during filming, so hopefully the film does well because of her presence."

'The Puppet' will hit theaters on June 20th. Hold on, there's a knock at the door...we'll be right back.
