No link between the episodes has been established, as they have happened within thousands of miles of each other, and in random locations spread through every continent, with several events in the U.S, Sweden, Colombia, Brazil and New Zealand.
Incidentally, an animapocalypse--besides being an awful blend of ancient Greek and Latin--could be an excellent term for the revelation of the unconscious mind.
