To dream of a magic potion represents a special way to alter or change a situation instantly. A method or “ingredients” to speed ahead. Not having to practice to achieve your goal or earn something slowly.
Negatively, a potion may reflect risky shortcuts or dirty tricks to get desired results faster. It may also reflect shortcuts that are dangerous in the long-term or speeding ahead with something you are not ready for. A method of cheating to get what you want instantly.
