Imagine being unable to move, you open your eyes and they are fixated on the same whitewashed ceiling.  In the peripheral vision there are The Machines.  Monitors and the ventilator on the right hand side, the console of automated drug dispensers on the left hand side.  Imagine not knowing really what is going on.  Worse, imagine people talking about you as though you are not there.  As a nurse, when you are in ICU and around people in comas it is easy to forget that Jennie is completely alert, her mind is active.  She is alive, trapped in a disabled body.
