Dream About Taking Test In Underwear

ad an Interesting dream. I was in a classroom sitting at a desk as a student, and taking a test. I'm looking at a map of China and Southeast Asia. The question asks about weather systems and what are the purposes for clouds forming between China and India. The answer was to connect them to the sea! I'm fairly confident in my answer but then see that I don't have any pants on and I'm sitting there exposed in my underwear.
