Question

Why did government leaders fear the Ghost Dance movement?

Answer 1

"To properly "ghost dance", one must first cease to exist within the plane of existence of the person being "danced". This entails hiding in walls as walls are in between rooms and therefore metaphorically between dimensions. Once one is in the wall, they use the sticks lashed to their hands and feet to scrape against the wall. This mimics the motion and sounds of feet sliding on the floor as someone dances. (NB: this can also be done from inside the floors between levels but it requires more agility.)

This caused great concern for US officials as they suddenly had to change building code regulations to accomodate walls and floors with enough space for 1 or 2 people to adequately "ghost dance" someone."
