A person flees through a swamp at night, and the heat and the landscape seem to chase them. The poem is written in the second person, so the reader is pulled into the running. Orange light picks the runner out, while Spanish moss hangs in the trees like "lace / made of barbed wire," a pretty image with a threat hidden inside it. The air is thick, stagnant, and hard to breathe, and the heat "slaps" and the rot "tangles" as if the place itself were alive and hostile.
The feeling is panic mixed with exhaustion. The final lines add something sharper: the cicadas sound like chainsaws, and the "manipulative hospitality" suggests that Southern politeness may be a trap. The mood is sweltering, claustrophobic, and uneasy. The speaker seems to be escaping both a physical landscape and a smiling, controlling kind of welcome.
