When writing speculative fiction, authors often come upon situations where they must explain things that do not exist in a way that the reader can understand them. This is not unlike trying to explain color to someone who cannot see or sound to one who can’t hear. You have things to reference, but doing so is not an easy transition. Sometimes, trying to describe things from an unfamiliar perspective is one of the most difficult parts of writing. This exercise is to take one sense and write about it as though it is newly awakened. Your character can suddenly see, or perhaps taste or hear, for the first time ever. They may or may not have a guide to help them understand what they see. Describe the scene around them for the first time using that sense.
