To dream that you are in a dairy, is a good omen. Much fortune will come your way and you will never be without the basic necessities in life.
Dairy is a good dream both to the married and unmarried. See Churning Butter.
To dream of being in a dairy shows the dreamer has been too weak natured in the past and have let others get the better of him/her. To dream of owning a dairy means you will have much good fortune and never be without the staples of life.
