The best writers do not police their imaginations. They do practice prudence, and they do censor themselves sometimes when they publish work publicly. But this doesn’t mean that they don’t hide esoteric ideas inside exoteric stories.
Write what moves you emotionally. Believe that you can write something that will make yourself cry, and you will. Believe that you can surprise yourself with your writing, and you will. That astonishment will carry over to the reader.
