I feel that I am always oblivious to these small details in the day to day. Off topic here, but one thing I love about David Foster Wallace is his ability to key in on details and minutiae without losing the purpose of the narrative. The confusion could simply be a component of the waking state. Maybe Audrey is just a projection of herself and her relationship with her family, specifically her stepfather. On the other hand, maybe there is no Audrey. That could be an interpretation of the whole sleep lab scenario and the comment by ¿Randall? about the appointment at the end. She seems confused about who she is, possibly suffering from some mental deterioration. The questions about Audrey, the marriage and Daddy lead me to an even darker impression. Randall's tediousness comes off as more of a criticism of Randall, potentially, by the dreaming Hope who is harboring the common animosity the sleeper has towards one attempting to awaken them.

Sipe's Saab early on, then, as the meeting with the sleep clinicians began, the surreal background, "the sound of a hand-held hammer. The thunderstorm in the beginning and Hope questioning if it was raining at the end seems relevant.

I think you're correct that this was all Hope's dream. I'm similarly flummoxed, but enjoyably so.
