Ordinary humans cannot change surroundings in the Wyld. The lack the ability to Shape.
   The raksha are players. The Wyld is a stage. In the Wyld the raksha's stories are horrifyingly real. Because of a Creation born's formed nature the further in Creation they are the harder they are for the raksha's Shaping effects to affect. Until then they are in Creation proper they are safe (at least from Wyld Shaping.) They can't make their stories if there is no dreamscape to work in. This is the reason people fear Wyld storms. It gives the Fair Folk a certain amount of ability to use their magic. In pure chaos there is nothing but what the Fair Folk make. Creation has slid away completely leaving no foundation for reality to rest on. An injury a Creation born suffers here is real. So far into the Wyld fantasy is reality. Life played out at freeholds usually in the form of court dramas is like a theatre and hungry courtiers feed on the emotions of those who are centre stage.
