Another exapmle of abnormal behavior is paranormal activity. In the ending minutes of the movie the main characters are laying in their bed(The movie is about this couple who believes their house is possesed by ghosts, so they record their bedroom when they sleep) and the husbands wife wakes up and walks out of the bedroom and proceeds to walk downstairs, the audience cannot see what is going on down there, but the lady continues to start screaming, the husband wakes up, and sprints downstairs only for us(the audience) to have heard a loud thud, the man is thrown at the camera in the bedroom(unconsciouss) only for the lady to walk in a few seconds later with an evil grin on her face!
