Shannon's intentions do not gauge her level of exhaustion. When the body wears down, if we don't take care of it, it takes care of itself. But compared to what Dad is going through, she feels she can at least be able to stay awake. Surely she can endure that!

She collapses in her chair.  Sleep will no longer be denied its privilege.   It wins over her desire to stay awake.   

Yet her internal struggle spurs on many dreams ---dreams filled with fear.
