I want a secret room in my house!
My Great Aunt and Uncle live in a huge old house that's been in her family since Christ was a corporeal. And I mean for like hundreds of years. Supposedly there's a secret passageway that runs between the dining room and the kitchen. I've never seen it though and haven't been there in over a decade so I can't remember if the wall thickness was different. She had extensive grounds and even a hedge maze! Her family is LOADED, my great Uncle married into her family. I was always WAY more interested in going up to the attic and poking around but never got to do that either.
As for Spirit animals and such, the night we moved into my current house, which was Halloween incidentally, I woke up about 2am to see a huge black dog standing in my doorway, silhouetted by the hallway light. From it's ears and face I could tell it was a Great Dane. I looked at it and then rolled over and went back to sleep, I just had the feeling it was looking in to check me out and nothing more. I haven't seen it since.
