Answer:
"His neck ached horribly; his brain was on fire, his heart, which had been fluttering faintly, gave a great leap, trying to force itself out at his mouth. His whole body was racked and wrenched with an insupportable anguish! But his disobedient hands gave no heed to the command."
Step-by-step explanation:
Ambrose Bierce's short story "An Occurrence at Owl Creek" tells the story of how the protagonist Peyton Fahrquhar's hanging on the bridge and his imaginary thoughts of escaping the noose. In the small time he had between the hanging and his death, he imagines all sorts of escape route, his plans and how he wants to live after the escape.
Though most of what was described in the plot are just the imagination of Peyton, there are also some instances where the plot or pain is real. This can be seen in the third part of the story where Fahrquhar details his 'imaginary' escape after he reached the water. He describes how he was escaping from the water, but the reality part of the imagination was when his body actually felt the pain from the hanging and pain that follows right after. "His neck ached horribly; his brain was on fire, his heart,.... trying to force itself out at his mouth". The pain was felt in his whole body, making it evident that the pain was real and not part of his imagination.
