I have a ghost named Emily who loves bright things. (and it is only a 20 year old house and we built it).
Came home from being away one time and there was a ball of bright orange yarn on the sewing room floor. I thought maybe I had left it on a shelf and it fell, but it was a good six feet away from the shelves, and there is a rug. Can't see it rolling that far. Then I found the rest of the yarn it had been with, had left it in a drawer.
Just today she left a line of 5 bright red hawthorns in the driveway for me - there are no hawthorn trees within 200 feet.
She is mostly good though, doesn't hide things. Sometimes I can feel someone touching the top of my head, think it is her.
