The missus found a story about one of these "ghost" things online the other day and said it was creepy and weird. There is a supposed child in the second photo in the bottom left that isn't there on the first. In my mind it is simply one of the masks the girls are holding, propped up against something that is obscured in the first photo. I don't believe in ghosts at all though and think everything can be explained logically given enough information.
The OPs photo is clearly someone walking along the pavement, but due to zooming in on a crappy image it looks distorted.
