How does Mine Okubo use imagery in Citizen 13660?

Example of Imagery:

"We 'hit the hay' around ten that night, but learned very quickly that sleep was not to be easily won. Because the partitions were low and there were many holes in the boards they were made of, the crackling of the straw and the noises from the other stalls were incessant. Loud snores, the grinding of teeth, the wail of babies, the murmur of conversation - these could be heard the full length of the stable. Moreover, it was very cold and we were shivering. One blanket was not enough to keep us warm. We got up and opened the duffel bags and the suitcases and spread everything over our beds. Sleep finally overtook us around midnight. Thus ended our first day in the Tanforan Assembly Center." (47)
