Answer: is trapped in a dangerous place.
Step-by-step explanation:
You didn't add the excerpt but I got the excerpt online from "The Most Dangerous Game."
From the excerpt, Rainsford could hear the pattern of shadow, and the black, noiseless forms, the hounds heard him and then looked up at the window.
He went to bed but couldn't get enough sleep as he was afraid due to the fact that he realized that he was in a dangerous place as he even heard a gunshot. The details of the excerpt show that Rainsford knows he is trapped in a dangerous place.
