How does Eliezer describe the barracks?

The barracks are long, bluish light comes in from the roof. Eliezer said he thought it was what the antechamber of hell must look like.

THE BARRACK we had been assigned to was very long. On the roof, a few bluish skylights. I thought: This is what the antechamber of hell must look like. So many crazed men, so much shouting, so much brutality.
