Here's why:
* Literal Meaning: The "ambush" in the jungle refers to a physical attack, a direct and concrete event.
* Figurative Meaning: The "ambush" that keeps happening to the narrator is a metaphorical concept. It suggests a persistent and unpredictable force that challenges or hinders the narrator's progress, potentially in the form of memories, guilt, fears, or other internal struggles.
By using the same word ("ambush") to describe both a physical event and an internal struggle, the author creates a metaphor that links these two distinct concepts. This comparison helps to deepen the meaning and impact of the story.
