'Friends' star Courteney Cox believes she encountered something supernatural while living at the top of a mountain in Laurel Canyon in Los Angeles. Cox told US OK! magazine: "My acting teacher used to come out and she'd say, 'It's weird. I have a feeling in this house. I keep feeling drafts.'

"Another friend came out and they had a dream where they saw this woman in a white dress who sat down on a bed next to me. I still didn't believe it, but one day the doorbell rang and it was a FedEx guy. He goes, 'Are you aware that there is a spirit in this house?'
