The Papersack Man

The Papersack Man is a ghostly entity of unknown type who appears in the dreams of people who have "offended" him. Normally, this offence often takes place by forsaking someone that you love dearly, for even a moment. He appears at first as a twinge of guilt, but then the affected will start seeing him. At first, it's just in corners... a writhing body wrapped in a straightjacket with a wet, crumpled paper bag on his head with eye-holes cut out.
After several maddening weeks of seeing the Papersack Man, the haunted individual will normally begin to find a bloody, rusty knife lying around in random places, at first once per week, then gradually increasing to be daily, and then after a month of seeing this knife it will be everywhere, lying on a surface in every direction they look. If they look away, the knife disappears without a trace. Each time the person sees the knife, they must make a Willpower roll to avoid using it to slash open their own throats.
Every time after the first that they see the knife in the course of one day, a 5% penalty is added to this roll.
