My parents bought the house I currently live in back in the early 90's...I think it was 1994, when I was about seven years old. It is a relatively large house, with six bedrooms and three floors (basement, main level, and upper level with bedrooms and bathrooms.) A contracting company built the house with my Dad's supervision, and it has been in my family ever since. However, from the first day we moved in, I was incredibly nervous being in the house. I felt like something was watching me most of the time, especially when I was alone in my bedroom or when I was going down the stairs. (I felt like something was standing at the top of the staircase, watching me.)
After a couple of months in the new house, things escalated a bit. One night, the window shade on my bedroom window snapped up on it's own. The floors and stairs would creak in a very distinct way, as if someone was walking around in the hallway. At night, every night, my bed would rock back and forth a little bit, like someone was standing at the foot of the bed, shaking it. My sister would hear something knocking on the bottom of her bed at night, and it would stop when she asked.
One evening, around Christmastime, there was a knocking on the walls downstairs, in the living room. My sister and I were running around knocking on other walls, and it seemed like the knocking "followed" us from wall to wall, to the extent that my parents were concerned that there were mice in the walls and called an exterminator. They didn't find anything.
As we got older the activity gradually subsided, to the point where I had mainly forgotten about it or explained it away to myself. I moved out of the house and lived in a series of apartments during college and right after, and nothing out of the ordinary happened at all in any other place I lived. However, I moved back home about a year and a half ago to finish school, and things seem to have perhaps started up again.
The house makes a lot of noise. Right now the floorboards upstairs are creaking. At night, the noise can be loud enough to wake me up. I have a dog I acquired during college and, although she slept in my bed with me while we were living in an apartment, she won't go into my bedroom here, and often seems to be watching something on the ceilings that I can't see.
I find a lot of weird little things. I know this sounds weird, but sometimes random little things will suddenly be on the floor that I don't remember owning or haven't seen in years. The other day I was in the shower, and heard something fall onto the floor, and when I got out of the shower one of my sister's rings was in the middle of the bathroom floor. I have a cat that sometimes knocks stuff off of tables or moves things around, but she wasn't in the bathroom and I don't have an explanation for it, especially since my sister's things are kept in her room and behind a closed door. (She currently lives in Australia and her jewelry box hasn't been opened since 2011.)
The house also makes my fiancé uncomfortable. He is currently living in an apartment nearby because he doesn't want to stay in the house with me. He says he feels like he's being watched, and things do happen a little more obviously when he is around. One night he was staying over, and after we had gone to bed the hallway light came on. He got up, turned it off, and closed the door on his way back to bed. A few minutes later, the door opened a couple of inches. We didn't get back out of bed, but he has refused to stay another night since.
The house is on a plot of land that my parents used as a small hobby farm. We have a large vegetable garden and a small barn with some chickens, my pony mule, and a couple of goats. When we were pulling up some of the dirt for the vegetable garden the first time, we found an old horseshoe. My mom cleaned it up for me as best she could (it's very rusty,) and it's been hanging over my bedroom door for sixteen years. Maybe that is behind some of this.
Nothing aggressive or threatening has ever happened, just mildly curious, and I've never thought to tell anyone about it before now.
