Eleanor’s belief that yesterday was “in a different life” is a bold statement—it shows the confidence she has in other people’s and things’ ability to enact meaningful changes in her life. Whether consciously or unconsciously, Eleanor chooses to believe in the transformative power of external forces (like a potential relationship with this performer). At this point, it seems that Eleanor seeks escapism through alcohol, painkillers, and fantasies of romance. This, combined with the mysterious wounds Eleanor sustained at age 21, suggests that she’s likely experienced some sort of past trauma. Further, the fact that she’s an unreliable narrator means that she could be intentionally hiding this from the reader—or perhaps even repressing it in her own mind.
