Anybody watch Ghost Hunters on Sci-Fi? It can be pretty compelling.

oh pls - ghost my S. i think that after a lesson or 2 with the proper software even a klutz like me will be able to create such a “ghost”

I'm convinced!!

Def not a ghost. at :28 you can see the thing in question pass IN FRONT the narrow black post. if the illusion was in fact true, the line of movement would put it behind the post. probably an ant or something.

No, you guys! There's no way that an insect could be that spooky. Insects are creepy and gross, but only ghosts are spooky. Watch the video again and tell me if it's “creepy and gross” or “spooky”, then you will know whether it's an insect or a ghost. Jeez!

Stuff like that has been proved a thousand times over to be a bug of some sorts crawling across the lens of the camera.

It's an insect!

No way, wine diva - that's a ghost, walking across the shopping mall. Didn't you read the title? “Chile Shopping Mall Ghost.” Fuzz would be way less scary.

it's probably just a piece of fuzz blowing up against the camera lens.
