::''This could be a reference to the TV show [http://www.imdb.com/title/tt0436992/?ref_=sr_1 Doctor Who]. There's an alien race called "Weeping Angels"; they look like stone statues of angels while you look at them but when you don't, they can move freely and incredibly fast. In the show it is always and repeatedly adviced to "not blink" because otherwise these creatures are able kill you during the split second your eyes are closed.
