The two sets of lines in this excerpt from Wilfred Owen's poem "Dulce Et Decorum Est" that suggest that even after the fighting has ended, soldiers continue to suffer the psychological consequences of war are:
1. "In all my dreams, before my helpless sight,
He plunges at me, guttering, choking, drowning."
2. "If in some smothering dreams you too could pace
Behind the wagon that we flung him in,
And watch the white eyes writhing in his face."
Both of these sets of lines suggest that the narrator is haunted by the memory of a soldier who died a painful and traumatic death, and that this memory continues to affect him even after the war has ended. The use of vivid, visceral imagery (such as "guttering, choking, drowning" and "white eyes writhing") conveys the intense emotional impact of the experience, and the fact that the narrator is still haunted by these memories suggests that the psychological scars of war can last long after the physical wounds have healed.
