I think the answer to this question came up later in the movie. During the time when all of the patients started getting back to life one of the nurses, Eleanor if I remember correctly, said something about not being strong enough herself to get through everything those patients did. She couldn’t stand the idea of being trapped in her own body for so long, being aware what’s going on around you and not being able to respond. In my opinion this doctor from the beginning was afraid of the exact same things.
