The darkness and Nightmares were different for each person, but the total effect was the same -- no escape, no hope, only despair, entrapment, and desperation. This doom is especially heavy because it is so paralyzing and draining.
In real life we can get just as stuck and deceived into thinking that there is no hope for change. But thanks be to God who gives us his spirit and hope which can open the doors not only to nightmares but can also break the chains of the burdens and cloying evils that ensnare us. Lives of freedom and joy even in the midst of trials is possible through Christ the Lord, who makes a way of escape, renewal and transformation for us.
