What is the worst nightmare for a ghost? What are ghosts afraid of? After longtime looking for it, we found that powerful modern vacuum cleaners are a real headache for them. These vacuum cleaners have a maximized suction power that does not let escape anything, even not immaterial specters, apparitions, souls, sighs of whatever of their kind. A normal ghost is easily sucked up and held captive in the same bag with microscopic dust, dirt, creepy bacterias and terrific microorganisms. Finally, the worst nightmare for a respectable scary ghost is to feel humiliated!
