The narrator is the protagonist of House of Day, House of Night, and a friend to Marta. Many of the chapters focus on her own thoughts and experiences, connecting her to the wider plot of the novel. Her primary obsession is with dreams, and the ways in which they shape the world. She loves reading other people’s dreams, seeing similarities between them. She believes that there is a yet-undiscovered science to dreams that if understood, would change how she and others see the world: “If someone were able to research this idea properly, if they could quantify the characters, images and emotions that appear in dreams, strip them of their motifs, and apply statistics […] maybe they would discover some sense in it all” (27). More than anything, the narrator is defined by her pursuit to make sense of what she cannot understand. To her, dreams create a bridge between the past and present as well as the present and future. This sentiment is reflected in her commitment to astrology.

Despite her obsession with dreams, the narrator struggles to find sure footing throughout the novel. Though she is at times a dynamic character— learning from Marta, using her knowledge to gain a deeper understanding of her home, and therefore herself—there is a confusion that resides inside her.
