You know, scientists of ghost believe that ghosts are merely replaying repeatedly what they did about a day before they actually died. For instance, my house is serveral hundred years old.There are ghosts in my home, and I'm not kidding. There are three good ones and one evil one, who terrifies my puppy when we turn out all the lights. How do I know this? It opens and closes the door of my kitchen. There is a Baby Gate so the dog can't get out, and on the other side is the door. Weird? Evil? Yes.
