Here's why:
* Literal Ambush: The "ambush" in the jungle refers to a physical, literal attack. This provides a concrete image for the reader.
* Figurative Ambush: The "ambush" happening in the narrator's past is a metaphorical representation of something that is constantly haunting or threatening them. This is abstract and may refer to trauma, guilt, or other psychological burdens.
The double entendre is created by using the same word "ambush" to convey both a literal and figurative meaning. This creates a sense of tension and complexity, suggesting a connection between the physical danger in the jungle and the internal struggles of the narrator.
It's also possible that the language employs symbolism, where the jungle itself becomes a symbol for the narrator's internal state or past.
Overall, the combination of literal and figurative language creates a rich and evocative experience for the reader, inviting them to explore the deeper meanings behind the story.
