It's interesting to note that the pattern is personified as a woman. The woman in the pattern parallels the narrator. She describes how the woman in the pattern is subdued during the day, and immediately after explains that her own days are often spent napping, something forced upon her by John.
This is an excellent synthesis of Adams and DuBois. The narrator is experiencing near-literal double consciousness, as she is seeing and being seen. Also, she has essentially moved to talking about herself in the third person, like Adams. The effect of all of them is in creating a narrative between subject and object.
