"I assume you don't want to do things like burning feces in the stove."

Interesting one Rap! Spirits - so I've read in folklore - are generally repulsed by stink! Many different cultures use strong fumigations to exorcise negative boogies. Pretty much all strongly scented herbs are usable for such a purpose. Even essential oils.

Not sure why this genuine folklore question is in BS though! IMO it quite legitimately belongs up there.. Fascinating topic.

Otherwise LadyJean, I'd say the most important thing is for you to find some practical and creative means to shore up your doubts and anxieties about this place, without becoming too paranoid or anything.

Do some research about folk charms and household blessings (the Celts specialised in blessings, I'll try to find you one suitable if I can) and then improvise your own wee 'clearing' ceremony with friends and family. Much folklore about clearing out boogies is pretty 'logical' if you think in a childlike way.
