If this reporter was anywhere else, I would probably say this is just a trick of lighting and leave it at that
. It probably still is, but the reporter was doing a story from Myrtle's Plantation which is one of the most haunted places in America. Neither the reporter or the camera person saw the ghost during filming, but only noticed what appears to be maybe be one during the editing process.
And of course my all time favorite “ghost” caught on camera. 35 seconds in.
