Jim the supernatural man

Jim we all know his superstitious ways. To the birds, not walking ways why? or how? i wonder is Jim like this what did he grow up on. is it just the slave brain thinking of ways to help it through the day? Huck is in a way but not as muck as Jim. I am in some ways, when i don't mean to spill the salt i have to through it over my right shoulder. It doesn't even process in my brain its automatic that i must do it. what makes the brain think in these ways is it mind over matter?
