I watched Deb do Sudoku for years, so I think she knew something was going on. And it didn't bother her that she didn't know the day of the week. My 'theory' is the experience is more like a very young child not understanding how life works. And like a 2-year old, can become very frustrated. When its hard to understand your thoughts it is exhausting so they sleep alot . I hope I'm right.
