A dream with milk suggests that you are intuitive, kind, or seeking satisfaction or balance in your home life. It may also imply that you need to be more caring and giving towards others in your life.
If you drink sour or bitter milk then it implies that you are having trouble finishing something in time or sticking to a commitment. You are facing obstacles.
If you accidentally knock over or spill the milk then it suggests that you have missed opportunities or have lost hope or trust in some part of your life.
