Quote #4
"There's nothing wrong with nightmares," Hungry Joe answered. "Everybody has nightmares."
Yossarian thought he had him. "Every night?" he asked.
"Why not every night?" Hungry Joe demanded.
And suddenly it all made sense. Why not every night, indeed? It made sense to cry out in pain every night. (6.20-23)
The men of the squadron live in such constant fear of losing their lives that it is understandable that they have nightmares every night. In fact, it makes so much sense to Yossarian that it becomes less and less probable that men would not have bad dreams every night.
Quote #5
Captain Flume spent as much of each evening as he could working in his darkroom and then lay down on his cot with his fingers crossed and a rabbit's foot around his neck and tried with all his might to stay awake. He lived in mortal fear of Chief White Halfoat. Captain Flume was obsessed with the idea that Chief White Halfoat would tiptoe up to his cot one night when he was sound asleep and slit his throat open for him from ear to ear. Captain Flume had obtained this idea from Chief White Halfoat himself, who did tiptoe up to his cot one night as he was dozing off, to hiss portentously that one night when he, Captain Flume, was sound asleep he, Chief White Halfoat, was going to slit his throat open for him from ear to ear. Captain Flume turned to ice, his eyes, flung open wide, staring directly up into Chief White Halfoat's, glinting drunkenly only inches away.
"Why?" Captain Flume managed to croak finally.
"Why not?" was Chief White Halfoat's answer. (6.31-33)
The men live under such constant fear that they have incorporated this emotion into their lives and have no qualms inflicting it on their fellow soldiers.
Quote #6
Hungry Joe's nightmares gave Chief White Halfoat the heebie-jeebies […]. (6.35)
This is one way of showing the contagious effect of fear. Hungry Joe's fears give him nightmares, which make him scream in the night. This gives Chief White Halfoat the heebie-jeebies, which makes him threaten to slit Captain Flume's throat.
