The other day I mentioned that I needed to get back to reading old fairy and folk stories. reading them forces you to forget about rationalizing and explaining everything. There is an assumption that wonderful and fantastic things just are, they do not need a reason for being there. Forget naturalism, embrace the irrational, spontaneous, and magical and just ride along.
Poking around, I refound a site that has the books of fairy stories edited by Andrew Lang online. These books were compiled in the late 19th century and contain stories from all kinds of different traditions. Each was bound with a different color cover, and they are titled after the color of the cover. You can find them in various formats, including each individual story online here. Go check them out.
