She feels the city as suffocative. She has claustrophobia. She is very responsible and is financially independent since childhood. She has a big fear from accidents and she doesn't drive for that reason. She has a dream that she climbs a mountain peak and everything is beautiful and suddenly there is a snowslip and she falls down and everything is lost.
