WTF subconscious?

Last night in my dream appeared a cauliflower tree, i.e. a tree producing cauliflower like fruit, even though I am well aware of how cauliflower looks when it grows, that it is a variant of cabbage, and thus grows on the ground. I might be alienated from food production, but not by *that* much. (Despite being a city dweller, I don't believe in lilac cows that are the direct chocolate producers either.)
