The interaction between you and your husband is critical to the interpretation of the dream. If you dream of him being aloof and standoffish, it may be that you need him to participate more in your pregnancy. Such dreams are not uncommon among pregnant women. They represent an understandable uncertainty about how the child will affect the marriage. Another great metaphor for the relationship between mother and her unborn child.
Jewels symbolize the inner self as well as the unborn child.
Dreaming of joy may be your mind's way of encouraging you to express joy more fully while awake. Cooking and baking symbols are rampant in pregnant women's dreams. The analogy is of preparation and nurturing. A knife also represents a penis, and may indicate the dreamer's fear of intimacy or sexual relations. Analogous to preparation for childbirth and parenting.
