One of Susannah's major concerns is the fact that she doesn't remember anything but hallucinations from her month in the hospital. To remedy this and to help her piece together what happened, she describes several scenes from hospital monitoring footage. These videos are the only unbiased evidence Susannah has of her time in the hospital (compared to the personal narratives of her friends and family, or doctors' interpretations as expressed in their notes on Susannah's charts). In this way, the videos come to symbolize the only real “truth” and unbiased record of what happened in the hospital. Similarly, the videos allow Susannah a window into the mind of the person she sees in the videos, a person she barely recognizes as herself. To this end, the videos are also physical representations of Susannah's split identity.
