Since the dream has died, it is time to make new ones and so it is time to brew beer. Beer is one of the few possible proofs that there is a god in the universe, but brewing your own beer reminds you that really god is not needed; just clean water. And so new dreams start again, this time with the help of some well water, yeast, malt and hops.
Brewing beer gives us a break from building other things and gives us a chance to remember what counts: time. This because brewing beer takes time. If you are not cleaning, then you are waiting. The smells waft from the kettles and there is time to dream new dreams.
