This ghost video shows a shadow ghost moving by the camera and makes a swoosh sound - awesome. Video by A.G.H.O.S.T. (www.aghost.us) and shot at Liberty Theater in Astoria, Oregon - 2006. Also, look at this re-creation of it by D. Eldon Bailey: Re-Creation Shadow Ghost Video
Here is a second ghost video of the shadow ghost moving about the room. It moves by the camera again during the same investigation as the first video.
