Dreaming of an auction means you are trying to put a value to an idea, task, or career. The outcomes are whether you win the auction, or lose the auction.
If you win an auction, that means you place a great value over the ideas that you have been fighting for, and will continue pushing forward over any obstacles that stand your path.
If you lose an auction, that means you are ready to throw in the the towel and walk away from what you deem is not worth the time and effort any more.
