I can't interpret your entire dream bakery, but I do know that whales can represent your own rebirth.
Whenever my subconscious is trying to tell me something I have the same theme running over and over until I work out what it means, then they will stop. One of these themes was the ocean and whales and dolphins. Nothing horrible like your dream (although I think in one dream a dolphin jumped out of the water straight into a brick wall and died), but sometimes these dreams were intimidating. One of them (actually I think it might have been the same dream with the dolphin) I was standing on a boardwalk over the ocean and I was terrified because it was so dark and big and I knew there were big things down there that I couldn't see, and I felt so small. Then I could see the shadows of huge whales swimming underneath me and I was scared. I always had these themes, whales, the ocean, for weeks. Then I finally interpreted what it meant. Whales as I said can represent a rebirth, and the ocean can represent your emotions, and I was at a point in my life where I wanted to start again, get over things (I think might have been around the time my mother was in rehab and I was getting stressed out and frustrated because my grandfather kept drinking around her while she was trying to get clean), I wanted to forget all of that and think of ME. And I've never had those dreams since.

As for the dream of being in a car, if you have a dream where you are driving a car but it's going out of control/the breaks aren't working, etc. that can represent you feel as though you don't have control over something, like your life for example. If your husband was the driver, perhaps you feel as though he is 'in control' of something in your life? And the cannibalism kind of fits into that as well-
