On the Discworld, doorknobs can come to life, Death can be put out to pasture and belief precedes the object of that belief. This is all due to the interplay of the life force with the phenomena of belief and metaphor (and of course narrative causality.) Or maybe it's all, as Mustrum Ridcully might insist, because of quantum.
