This is what Grace said, in sequential increments, after I gently asked her to stop reading over my shoulder:

I am just going to lie down on the couch…

and use my mind…

to keep busy…

and make objects move…

and race across the room…

and watch them.

And so I watched eight-year-old Grace, and that indeed is what she seemed to be doing. As she lay on the couch, her head swiveled as though tracking something, and her eyebrows occasionally tented in surprise. Her lips moved, ghost talking.
