I find that suggestion about using dried sage interesting because its very similar to one my mother told me once. Where she grew up (Abruzzi region of Italy), they would use straw in a little bundle to keep out an assortment of ghosts. I wonder how far back this idea goes and where it started?
My mom doesn't believe in ghosts by the way, nor do I. Ghouls, fairies and spirits are fantasy to me too.
I'm throwing down the gauntlet. If there are any succubi out their, prove it to me.
