Final answer:
Footprints and Crusoe's dream on the island can reveal the insecure psychology of the invader.
Step-by-step explanation:
An understanding of footprints and Crusoe's dream on the island can help us understand the insecure psychology of the invader by revealing their fears, vulnerabilities, and anxieties. In the story of Robinson Crusoe, the footprints left by unknown individuals create fear and paranoia in Crusoe's mind, making him question the safety of his territory and his existence on the island. Similarly, Crusoe's dream reflects his inner insecurities and anxieties, which can be extrapolated to understand the psychological state of an invader in a foreign land.
