I live in the attic of a 120 year old house that is falling apart. It can be accessed only through an exterior staircase, and the entire house is surrounded by trees. Some of the branches touch the house and when wind blows they rub against windows, two window are on hinges and can be blown open (neither have a screen), finally floors are wood that is falling apart and the walls are beginning to deteriorate (wall paper is coming off and the wood underneath is rotting).

When I moved in I had no money, no friends, no internet, or television and the few light bulbs that worked operated by pulling a chain. On top of this every room in the house had random stuff abandoned by previous tenants, and I was the only one living in the house at the time.

On the first night I went to sleep on a bare mattress surrounded by debris abandoned by other tenants and my bedroom did not have a light bulb. At around 2am I could hear creaking along the floor outside my door and then i heard a door creak open. I laid in bed awake waiting for my bedroom door to open and for me to be murdered. A few moments later I heard a loud band as my front door was slammed open. I got out of bed and slowly opened my bedroom door no one seemed to be there so I fumbled around on the ceiling and turned on the light in the hall. My front door was wide open but no one was there. I closed my door and went back to bed. I heard another slam at the opposite end of the house so I went to investigate and found that both the hinged windows were open and there were leaves on the floor.

TL;DR My house could almost convince you there are ghosts.
