The oven can predict food in the future. At the moment, despite everything, you must wait patiently for the reward. For Freudian psychologists, the oven symbolizes the uterus and denotes pregnancy. So it may be that you are incubating new ideas or attitudes. (See alchemy , cooking , fire , and blacksmith ) To cook something in the oven is a sign of changes. If the oven is hot, the change will be good, but if it is cold, you must be prudent.
