Clothes: If you burned a hole into one of your outfits, someone is about to spread a false rumor about you (eh, normal day in tengaged)
Knives: Never close a pocket knife or Swiss Army knife that you did not open. If you will, you'll take on yourselves the same troubles as the man who opened the knife.
Mirrors: If a mirror falls and breaks for no apparent reason in a house, someone in that house will die soon.
Hair: A knot in your hair means that someone is thinking about you (so if I'm bald less people will think of me?)
