I saw a ghost once in my grandmother's atticl  It was the weirdest thing.  I was up there getting some tools form my granpa's old tool box, and I hear a noise over in the corner...

 When I walked over to the corner to check it out (I thought it was a rat) the hatch that I had come in through closed shut.  I turned on the light above me, and as soon as I did, this face appeared right in front of me.  I screamed so frikin loud.
