We've lived in a few places through the years that had strange stuff happen.
The first was a half double/duplex that was built in the early 1900's.My sister in law lived in the other side.Several times when she wasn't home,we would hear someone walking up and down the stairs,opening and closing cabinets,flushing the toilet,etc. like someone was over there,even though nobody was home.On our side,it was always playful type things.I hung a towel on the shower rod and walked out of the bathroom for a minute,but when i went back in,the towel was gone.I went and asked my wife if she moved it,she said no,and when i walked back in,it right there hanging on the rod again.We had a cat and a dog that would absolutely not go up the stairs.The dog would sit at the bottom of the stairs and growl and bark,the cat would get to the bottom and arch her back and hiss,neither would ever go up those stairs.
The worst place we lived though was a house we rented for a short while.We looked at the place and it seemed perfect,so we signed the lease that day,and agreed to do some painting,etc. to cover the deposit.I went over by myself the next day to start painting,and within 5 minutes started seeing stuff,but i blew it off thinking i was just tired.That went on for several days,but i never said anything about it to my wife because she would of freaked out and not moved there haha.
I was talking to a guy i worked with,and told him we had just gotten this house.I mentioned the street name,and he got a worried look on his face and said is the address ----,he had it right on.He warned me that his step son had just moved from there,and started telling me all the issues they had there.I still didn't tell my wife about it,as we really liked the house,so i blew off all the stuff i had seen and what he had told me.
About a week after we moved in.me and my older son went night fishing,leaving my wife and youngest son at the house.We got back around midnight,and my wife was sitting out in the front yard with my son,and she refused to go back in the house until i checked every room.She had seen and heard people and banging inside the living room wall.We had the cable guy come out to install cable,and when he got to that living room wall,which was the living room on one side,and our bedroom on the other,it took him over a half hour to drill a hole through that wall,which was just 2 pieces of drywall,he didn't go through any studs.When i mentioned this to the guy at work,he said his step son had a medium come to that house when he lived there,and she told him that wall was a portal of some sort.Everything we witnessed in that house for the short time we lived there revolved around that wall.Pictures on that wall would rattle if we argued,our tv in the bedroom that normally had a blue screen if it lost the channel would turn red instead of blue,and just a bunch of other weird stuff in the house.We didn't find out until after we moved,that one of my wifes cousins had died of an overdose in the shed behind that house about a year before we moved there.We only stayed about 3 months,after that we found out there had been 28 different people who had rented that house in less than 2 years,most moved back out within a few weeks of moving in.
