like sleepwalking through small villages and sacrificing their goats to Cthulhu

I had that problem for the longest time. The solution is to bind your ankles with rosary beads and annoint your doorway with ground sage and the saliva of a baby lamb. It's actually more of a hassle to get the lamb spit cuz the babies are all wriggly and "maaa, maaa". It's almost easier to just kill the goats, or even to kill the lamb as well as the goats, and after wrestling with the lamb you'll think that's rather a fine idea. But in the end, if you value your eternal soul as well as the fate of the human race, you should take the extra time to do the sage-and-spit thing.
