It was strange getting used to at first. I don't... actually talk about them much. The dreams.
I cannot recall a single time that we've actually done that, not at least while I've been the Captain. Perhaps other raiders are doing it. We do tend to prey on each other in that fashion, though - especially if another among us is being a dick. But generally not on towns and villages. Usually more used to putting in for supplies and some time ashore for my crew than burning those places to the ground and such.
