Interesting dreams, and I agree with Yaowen, not very fair. One never knows, so please take this with a grain of salt, but I hear themes of mastery and security. On a completely superficial level, are you wishing to slim down your physique to make a more professional or stylish impression, lol? Silly, but maybe. But on a deeper level, food equals security, and you may feel somewhat insecure about seeing your benefits end, or insecure you will competently assure security for yourself, or possibly for others since the food are also people who need to get to safety. Both dreams have to do with mastery, managing a sinking boat and effectively steering it into dock. Skiing and instructing relate to mastery, and perhaps guiding another in a parental or teacherly manner, or perhaps you are coaching yourself. In any case it sounds like your dream is telling you that you have the capacity to do it! Skiing can also feel very liberating, especially when you know how to stop effectively! And of course mastery easily connects to work and employment, especially as one is in a position of judgment during an interview process.

Wishing you the best in your endeavors. You got this!
