someone has hold of her ankles and are sliding her 3cm backwards and forwards in a loop on the ground. This is because she has an itch on her back and this way it's being relieved. The relief shows in her facial expression and sounds she's making. No other hands to appear in the scene other than her own. The camera doesn't move at all. She continually strokes the top of her dress with both hands to ensure that there are no wardrobe fails   She tilts her head right back at the end.   No music, talking, just natural sounds
