I saw a ghost once. Downstairs taking to my cousin in a darkened room, only my cousin was upstairs at the time and no one else was downstairs but me.
Once while watching tv in the finished basement I heard the chairs moving across the floor in the kitchen, wnet upstairs to see who was home. No one was.
As a small child I had to attend the funeral of an aunt, later at the wake I turned a corner and there stood the dead aunt.
No one told me she had a twin sister.
