Called the “Dance of Souls,” this ritual involves people getting temporary skin piercings, through which hooks attached to ropes are placed. The ropes of one person are connected to those on others in the group or to a fixed object and are pulled taut as music or drums are played. These events are also known as “energy pulls” and are seen as primarily spiritual, not sexual, [Northern Illinois University’s Brad] Sagarin [pictured here] told Live Science.
