Silver's Dreams

What did Silver dream about?
It's clear that animals were important to her. She took every chance she could get to ride the white horse in the livery in Leadville. Did she dream of riding away forever? In Freud's Interpretation of Dreams (1899), he suggests that dreams can be unresolved issues from childhood, or the mind mulling over a day's events, or any number of interpretations. Did Silver's dreams scare her or soothe her? What did she see when she closed her eyes? In her dreams did she become the successful writer, the well loved matriarch with several children and a farm full of animals to care for? Or did her dreams scare her? Did she self-medicate because her dreams, like her reality, were too harsh, too difficult to handle?
