Horror film in real life

So I was goofing off with my roommates on skype. I was in my room video chatting with two others. Princess Aurora started teasing me so I ran into the other room to tackle her. When we settled down we looked on the computer screen and realized that my skype was still running and staring at an empty wall. As we stared at my empty wall, all of the sudden another of my roommates popped her head into the vision of the camera for a split second before pulling out again. All of us screamed! We did not expect that to happen!
