Read the passage carefully:

The heavy, tarnished silver hand mirror had belonged to Clara’s mother, and to her mother before that, yet Clara rarely looked into it. Instead, she kept it face down on the dressing table, where its intricately carved back—a tangle of ivy choking a rosebud—caught the pale morning light. Today, she picked it up, her fingers tracing the cold metal and the deep, dark spots where the silvering on the back had begun to peel away like dried skin. When she turned it over, the glass itself was flawed, warped by age and dampness, distorting her reflection so that her eyes seemed set at uneven heights and her mouth looked permanently pinched in worry. She tried to wipe the glass with the hem of her apron, but the smudge was within the glass itself, a permanent cloud trapped between the lead and the backing. In the reflection, the wallpaper of the room behind her—a pattern of fading blue stripes—seemed to bleed into her hair, blurring the boundary between her own figure and the dusty, quiet room she had lived in for forty years.

In the final sentence of the passage, the image of the wallpaper 'blurring the boundary' between Clara and the room serves primarily to suggest which of the following?
