What is the theme in Eyes of a Blue Dog by Gabriel Garcia Marquez?

Loneliness and isolation is the main theme of this story. García Márquez portrays the narrator's dream world as a place of loneliness and isolation that will not allow an intimate connection between two people who desire each other. The narrator and the woman cannot touch each other, meet in waking life, control when they see each other in dreams, nor stay together when a noise distracts them from their sleep.
