It takes a long moment for her to even understand the question; it becomes clear quickly that she's frowning less out of unhappiness and more out of confusion. Even when she understands the question, she doesn't really—how is she going to sleep? Why is she going to sleep? If she's going to sleep and will be unaware, why would she want anyone with her? It won't matter who's there while she's unconscious, and who has the time to be bothered standing around uselessly? How can she express any of this when her brain feels like it's sizzling like a cooked egg?

She can't. Not with any sort of coherence, anyway, so she just shakes her head.

(Bad idea, now everything is swimming—)

"Bad question. Doesn't matter."

She came into Thedas alone, if she leaves it alone, that's alright.
