Lovely house!
I live in a 300-year-old farmhouse, which is definitely haunted.
Weeknights, usually Tuesdays or Thursdays, between 7:30 and 8:30, I can hear the front door open and close, and someone walking and talking quietly (men's voices) in the parlor. The first few times, I thought it was DH coming home early. Nope, when I went downstairs, all was quiet and locked up tight. Can be heard from other rooms, too, and the creepiest was when I was in the kitchen, which has a door on the parlor. Literally, I was sure DH was no more than 5 feet behind me, it was that clear, and I actually said "hey, how was work" before I turned around and realized no one was there.
At 7:30-8:00, other nights, if I'm out in the backyard for any reason, a man walks across the lawn from the back door of the house towards the back garden. He wears a dark shirt or jacket, short pants (those kind that stop around the knees), and has shoulder-length hair. Again, first time I saw it out of the corner of my eye, I thought it was DH in his baggy shorts and told him to go get me some more clothespins.
My dog sees him too and freaks out, he goes nuts with growling and barking.
And then there are the weird smells. Ham, even though there hasn't been a ham baked here in over a year, but unmistakably ham, all through the house. Smell of a fire in summer, when the weather has not changed and there's no wind blowing through the chimneys or anything. Kerosene, even though we keep our antique kerosene lamp empty.
