My sister kept complaining that she was afraid to sleep in her
room at night because she was seeing a ghost in it if she was to
wake up during the middle of the night. My mother went and found a
horseshoe and nailed it up above my sister's door frame with the
intention that if the ghost would try and come into her room again
it would hit its head on the horseshoe and go away.
