Security cameras at a Kansas gym caught a white ghostly image flitting amid the dumbbells in the middle of the night, spooking the facility's owner.

The possible fitness phantom floated around the nautilus and weight-lifting equipment for about two hours in the Overland Park Anytime Gym, which was empty, according to KMBC-TV in Kansas City. At one point, the orb lingered by the dumbbells.

The motion-sensitive camera was set off a total of about nine times between about 2:20 and 4:14 a.m. on Sept. 12.

Gym owner Kim Peterson said she called her security company to review the footage. They ruled out insects, dust and headlights from the outside.

"I said, 'Is there a light bulb going out or do I need to get up and clean the lens?" she said. "They reviewed it and said, 'We have no idea what that is.'"
