it's the Ecto Goggles component, see the picture below as has a simulated ghost in the round glass but what is supposed to happen is you need to find particular ghosts and they appear in the see through round glass and maybe the lcd screen that reflects the image is behind the Ecto Goggles plastic / bracket
also Nino you mentioned the cloudy ramp, a insider said it is a proto ramp so should be much clearer
