We had a few odd things happen when we moved into our new house, strangely centred around dogs.
It’s an extended bungalow and we were converting two bottom bedrooms into a kitchen/diner. There was a lot of dust, naturally, so one day I decided to mop the Lino flooring in the hallway. A little later, I noticed a set of what looked to me like wet dog pawprints tracked from the wet hallway, through the dining room and into one corner of the kitchen. Only in one direction though. And we didn’t have a dog.
Shortly after, as I was fitting the kitchen, we had a lot of boxes etc. in the dining area. I turned back around and our plaster Jack Russell (don’t ask) had been placed squarely in the middle of the dining table. I might have done that, but I’m still certain I didn’t.
Also, in the old house, we had a baby monitor in my daughters nursery when she was a baby. We had bare floorboards, so anything could be heard over the monitor. If her dummy dropped out, it was clear downstairs and we could go upstairs and give it back before she noticed it. One night we heard the familiar clatter and I went upstairs to give her back her dummy, only to find that she already had it.
