Footsteps and door slamming back with a vengeance

There had been very little of the ghostly footsteps and the door slamming hadn't occurred in a long time. A couple days ago this all changed. I was working in the attic putting away left over christmas decorations and such that I couldn't fit into our Christmas room (a room over the front door that was used as a chest or storage room in the 1800s). I had just finished that chore and returned downstairs. I should note here that when you are in our attic you are totally cut-off soundwise from the first floor. Upon arrival in our kitchen which is on the first floor, I was greeted with, "Who was at the door?" by an angry wife. "How would I know, I responded, I was in the attic." No you weren't , she replied, fire in her eyes, You came stomping down the stairs, stomped your way through the diningroom and slammed the dinningroong door on your way there" (front door). " Just finished taking that stuff up to the attic and putting it away," I replied. "I wasn't aware there was anybody at the front door." "Well the dogs were making a**es of themselves and you didn't hear it?" she said. "No I didn't". I then went through the dining room opened the door then proceeded through the Parlour to the front door. Nothing was amiss; the front door was locked and barred from the inside. Anyone going out the front door would have left the door unlocked and unbarred. But everything was as it should be. I have no idea what my wife heard stomping down our rear stairs and slamming through the house. We're the only ones here except our two two miniature schnauzers and I'm sure they can't stomp very loud nor open and slam doors. There are two other doors, one leading out of the diningroom to the lower section of a double porch; but that door hasn't been used in years, is locked and barred and my wife has furniture in front of it. The only other door leads off the end of the downstairs hallway and onto the same porch. But hereagain, the door is locked and barred, has plastic sheeting over it (It tended to let in a good bit of cold air) plus there is a rocking chair and ladder in front if it. So whatever went stomping to the front door must still be in there because there is no way for it to exit except by sliding a bolt and unlocking a door which, obviously, never happened. So what did my wife hear? I caught the blame; but I was in the attic. We've had footsteps frequently over the years. We have even heard stomping on a couple of occassions usually in regard to the attic. Doors opening by themselves is fairly common even locked doors have been found open. This is the first time the steps were stomping from the rear stairs through the house along with a door slam. It apparently had the dogs upset as well. And here I had just posted, a few days ago, how quiet the house has been this winter.
