What dream makes Anakin leave Naboo and go to his home planet of Tatooine?
Answer
His mother suffering
The dream that makes Anakin leave Naboo for Tatooine is a vision of his mother, Shmi Skywalker, suffering.
In Star Wars: Episode II—Attack of the Clones, Anakin is assigned to protect Padmé Amidala on Naboo. He begins having nightmares that his mother is in pain, and he becomes convinced that the visions are a warning. Despite Obi-Wan Kenobi’s orders to remain with Padmé, Anakin decides he must return to Tatooine to find Shmi. Padmé goes with him, partly because she understands how deeply he fears losing his mother.
On Tatooine, Anakin learns that Shmi had been freed from slavery and married the moisture farmer Cliegg Lars. Cliegg explains that Tusken Raiders abducted her while she was gathering mushrooms. Anakin finds her at their camp, but she dies in his arms. His grief and rage then lead him to massacre the Tusken tribe, a pivotal step in his eventual fall toward Darth Vader.
The wrong options describe unrelated ideas: falling teeth and falling are generic dream themes, while becoming Darth Vader is a future transformation—not the dream that sends him back to Tatooine.
