You could have a visitor. We seem to get visited often. My dad says he's seen my grandad's shadow a few times walking through the hallway. We smell flowers whenever my mum has visited, I mean we smell then in rooms we don't keep them in. And my baby, Princess (my black lab), visits, I hear her paws on the kitchen tiles and her barking. And when we put the christmas mat down, you know the sort that makes a noise when you walk on it, she sets it off.
