Ghostly dog

     We had overnight guests a few years ago. When they came down to breakfast, they said, "We didn't know that you let Gamin run loose in the house at night."  I replied, "We don't; shes tied to the radiator beside our bed at night" They replied," Something was scratching he** out of our bedroom door last night. When I got up to see what her problem was, she wasn't there."  Strange and unlikely that they would both have the same dream..
