I have dreams like that! I can't balance on my horse and gradually it becomes apparent that it's because of my extreme obesity and massive folds of fatty skin, or I'm standing on the scales and they say something thrilling but incompatible with life, like 25kg, but my naked reflection on the shiny surface of the scales is a horribly unflattering view of my rolls and rolls and rolls of lard from below.
I dream about eating creamy cheesy pasta a lot too and wake up feeling a bit panicked for a few moments until I go over the day before.
