The milk in dreams is mostly a good omen. If you bought the large quantity of milk in order to sell it to others, you will experience the luck within your business matters. The milk that is wasted or given to others for free, shows the generous aspects of your personality. You give more to others than you receive from them. If the milk was spilled, you will have regrets for trusting your friends, because they will bring you misfortune in your business deals. If you drank the milk, but was not able to swallow it, you are in huge danger that was caused by those you trusted.
