I think we need to call the doctor

Last night, about an hour after Jagger had been put in bed, he came into the living room and shared some startling news with Grant and me.

He said, "When I go to sleep, my stomach is still alive, and tonight my brain fell all the way to my stomach!!! That's why I can't go to sleep."

Has anyone ever heard of this medical condition? I don't know what to do. Should I call the doctor? I don't know much, but I do know that a stomach is no place for a brain to fall.
