When you’re sickly, you are not allowed to eat certain foods that fall outside your permitted categories. Eating and drinking are rituals which you follow strictly because your doctor was warned you of impending blood tests. Because of your desire to taste delicious foods that you are banned from savoring, you are likely to dream of these foods. Dreams are experienced because of your internal want to get wishes granted. In your dream, you’ll see yourself eating and drinking to your heart’s content.
