Re: private.
I can sleep. I did it more when I was first a ghost. I don't do it as often.
I've been all over the campus trying to see if there's any connection to my key. There are a lot of classrooms, some of the doors are locked and I can't get into them or find regular keys for them yet.
Someone must have died in the kitchen though, because George could see me there. He said I could be his taste tester.
