strange activity early this year

     Strange activities are early this year. Today as I was answering E mail from the computer in the Library, I distinctly heard heavy footsteps go though the Diningroom. My wife was not at home, my dog was lying in the floor in the Library but facing the doorway into the Diningroom. When the steps were heard, my dog began growling; obviously he heard them too, and for whatever reason, but did not assiociate them with my wife. Which, of course, they were not. Moments later a door was shut hard, almost slammed, and the footsteps, lighter this time, again crossed the diningroom toward the parlour. This time the dog growled and moved away from the doorway toward the den. I left the computer and checked the Diningroom , Parlour and Kitchen. I found no one and nothing amiss. My wifes car was not in the driveway, so she wasn't home to make the sounds.

Today I saw "it"

     I was playing with the dog in the den. I was sitting on the floor, facing the library door, and the dog was in front of me, we were playing tug with one of his many toys. I distinctly saw someone wearing dark clothes with a white collar walk into the library. Thinking it was my wife, I  made a remark about the dog; but got no response. I got up and walked to the library door, no one was there. Noone could have left the library without my having seen them. I then went through the library and through the dinning room into the kitchen where my wife was working on a craft project. I ask her if she had gone into the library for anything and she replied ,"no". This is the first time that I've seen a "human" enity. My wife saw the child; we have both been witness to a small white with brown spotted dog on the rear staircase; but this is my first encounter. Strange, it happened so fast I really had no time to react to it. I do not remember the head, but plainly remember the dark clothing with a spot of white about were the collar would be.
