Paramount Pictures has debuted yet another clip from Paranormal Activity 4 featuring Kathryn Newton as Alex. In the last clip from earlier this week, Alex was seen levitating over her bed while still in deep slumber. Today's scene shows the young woman trying to determine where a variety of bizarre noises are coming from in her house. Take a look at this video, which also includes a brief glimpse of what appears to be a ghostly Katie Featherston.
