The moment a 'ghost' floated across the entrance to Dover Castle has been caught on camera.
The CCTV footage shows a dark figure moving across the entrance before a security guard walks over to take a closer look at the strange 'spectre'.
The video was uploaded to YouTube by a user called spyder1spanner2, and, according to the Mirror, a caption with the footage reads: "I promise you this is not a fake. It's filmed on CCTV at Dover Castle on to a mobile.
"I wouldn't even know how to start making this a fake, to be honest."
The footage appears to be from 2011, but has just started to go viral.
According to the Dover Express, one viewer, Louise Hampton, said: "This is a great footage! Looks like it tried to manifest. One can see how the legs were actually walking."
Another user was a lot more sceptical, writing: "It doesn't look that much like a ghost more like a car going past and it's just light reflecting off everything and makes that part seem a tad darker. "
Dover Castle is a medieval castle in the town of the same name in the English county of Kent, and is the largest castle in England.
