In 18th century London, an Sunday afternoon's recreation might consist in going to the Hospital of St. Mary of Bethlehem (shortened to "Bedlam" from where we get the word) to watch the poor, insane, inmates roll, scream, and jump around. Such gazing on the insane was later judged unseemly, and the hospital was eventually turned into the Imperial War Museum (trading one insanity for another). Watching this video of a group on Indian pentecostals is almost as sick. Of course the people who produced it thought it was something beautiful for God. That's sick, too.
