At the World Economic Forum in Davos, Switzerland, Julianne Hough twitched and screamed as if she was the subject of an exorcism. However, Page Six reports that she was actually receiving an energy treatment and was helping demonstrate the process to an audience. “There’s always a huge dissipation of energy and the feeling of relief, release, freedom. Expression of emotion may happen when the system moves," said Dr. John Amaral, who was performing the physical treatment on Hough. Jackie Schimmel Haas uploaded a video of the moment online, saying, "Gonna tell my kids this is 'The Exorcist'." Fans expressed shock and amusement as they responded to the video. On Thursday, Hough's brother Derek defended his sister's willingness to participate in such an odd display. "This stuff looks whacky and crazy but diving into it with the understanding of pure energy is a pretty wild experience. Maybe ahead of its time but worth an open mind," he said.
