One day she observes about his sleep habits, "I think the way you stay up as long as you can is an example of being inefficiently impatient."
"Well," she says, "when you stay up, you certainly have more done ten hours later than you would if you went to sleep. But since some of the things you want to do are 'magic' and 'lucid dreaming', I do not think you have more done a year later than you would if you went to sleep."
So she tucks him in and has him close his eyes and relax and then he is asleep.
That is good. He can help her feel out the fuzzy bits of the spell that way.
