Zack had a dream about visiting Dubai in the past and present. He saw tall palm trees and camels in the desert. He entered a tent and met a man and woman wearing traditional Emirati clothing. The man explained to Zack that he was in Dubai, one of the seven emirates that make up the United Arab Emirates. Zack learned that Dubai has developed from a small city in the desert to a modern city with skyscrapers like Burj Khalifa and a new airport.
