It surprises me you're not hallucinating me in nothing but my chemise, frankly.

[That's kind of dirty talk? Probably more on the realm of not, though (and for the record, she is pleasantly surprised he knows what physiology means). But she waves a hand, aware her own musings are more cryptic than helpful.]

My friend-- Alan, we'll call him, for the sake of privacy-- was both bitter and angry in our conversation, and he hallucinated something that infuriated him. He grew angrier, which fed into the hallucination, which made him even more upset . . . it became a self-sustaining cycle.

So. I wished to see if any strong emotion would trigger a hallucination. And there's fewer emotions stronger than lust-- it's why I wanted to run this with you, given our previous activities.

[Which sounds clinical, and is, a little. Her theory was that he'd have an easier time giving in to lust because he's proven he's attracted to her. But there's another meaning, which is: I wanted to run this with you because I don't want some stranger imagining me in such a state.]
