Feeling of Overwhelm
The narrator says, "I scarcely dared to look around me" because she was feeling overwhelmed by the grandeur and opulence of the building she was in. The setting around her was so luxurious and unfamiliar that she felt out of place and intimidated.

Sense of Inadequacy
The narrator's hesitance to look around also stems from a sense of inadequacy. She may have felt like she didn't belong in such an elegant environment and that she was not worthy of being in such a place. This feeling of inferiority could have led her to avoid looking around and acknowledging her surroundings.

Intimidation
The opulence of the building and the people around her may have also made the narrator feel intimidated. She may have been afraid of drawing attention to herself or of being judged by others in that setting. This fear could have prevented her from fully taking in her surroundings and exploring the space around her.

Unfamiliarity
The narrator's reluctance to look around may also have been due to the unfamiliarity of the place she was in. She may have been in a new or unfamiliar environment, which could have caused her to feel disoriented and unsure of how to navigate the space. This lack of familiarity may have made her hesitant to fully engage with her surroundings.
In conclusion, the narrator's statement, "I scarcely dared to look around me," reflects a combination of feeling overwhelmed, inadequate, intimidated, and unfamiliar in the luxurious setting she found herself in.
