In Intro Psych for Subtle Artists, there's a discussion of what subtle artists do with their own minds, and how this differs from everyone else. Bella has already talked to all her subtle arts professors about her own peculiarities, and Professor Murray has her talk a bit about how she's used lucid dreams for introspection, self-modification, and memory boosting. Professor Murray then explains that people who aren't subtle artists can only rarely lucid dream, and even those who can don't find it an effective jumping-off point for any heavy-duty self-searching.

I'm not saying it wouldn't blow up, I'm saying on balance it would probably be better for a greater number of people to have the information known. I'm also not sure anyone will believe an anonymous tip.
I don't want to get them killed either! For all I know they are perfectly nice people and would never eat somebody who didn't ask nicely first! But I don't want to get their friends' future meals killed either.
You could warn them, send them off to lie low or wait till they're home on vacation.
If they or their friends eat people who aren't nymphs then the people they eat don't get to come back, [Celo's name].
She considers arguing with him. She decides not to bother. If he doesn't care, he doesn't care. If there's a way to make someone care, she doesn't know it, and wouldn't do it anyway because that's one of the things she cares about.
Instead she says:
Why did you tell me, then? If it doesn't matter if people die unless they eat you alive when you ask nicely?
