My friend keeps on telling how there is a ghost in her house, and it scares her son, and keeps on lighting candles. Which could be a fire hazard really. She told me that she has tried to bless her home with holy water, and use prayers and yell " In Jesus name leave this house" and such.. So I jokingly told her that her ghosts were atheist.. but then I actually pondered it. Might it be possible?
