After the first time Strange appears, Grant, who usually has no trouble at all falling asleep (from what I've read anyway ;)), finds himself lying awake staring at the mirror, unsure if he wants it to happen again

and/or

He talks in his sleep when Strange is there, saying things that he would consider entirely inappropriate if he were awake, and Strange kind of half wakes up and hears him but then in the morning wonders if he really heard it or just dreamt it

Help me I can't stop thinking about this
