I think my dub brainwashing went a bit funny during my "Demons are everywhere scream like a girl and kak your pants!" indoctrination because I've never believed in any of that sh*t.
One thing the truth did do for me was free me from stupid superstitions that exist in the world. I can walk under ladders, spill salt till I'm sick of doing it and even go boo at black cats crossing in front of me. Its all a load of poop.
As for dubs believing in that sort of thing, I always noticed it was the less intellectual sisters that came out with superstitious rubbish like that. The type that had they been worldly they would have been living their lives according to what some tabloids horoscope had said.
