Dream of a vineyard means there has been some gambling in waking life. Or a game of chance is happening in your waking life. A vineyard of grapes is a risky venture since the crop is susceptible to weather, insects and condition of the soil. It is a long way from being made viable as a source of income for the grower. In fact, it is so tough raising a vineyard as a cash crop, that it is a kind of gambling process. In reality, many farmers who grow grapes as a cash crop face enormous challenges. The geography of the farm is important.
Dreaming of a vineyard can mean you face difficult conditions in your job or home. You face a tough challenge to think about what you can do to improve your situation. You could be the vineyard (the object). Where you can not uproot yourself to another place, you have to think of ways to cope with your present circumstances, in the place where you’ve been planted.
