I moved into this house about seven years ago in 3rd grade. It's about 95 years old now, and I've had a few experiences that I'd like to share.
My first experience in this house, I can't remember how old I was, I was home alone and because it was late at night, I was already pretty paranoid. At the top of my staircase, the wood squeaks when someone is about to walk down the steps. I remember hearing faint squeaking, and out of the corner of my eye, I saw a faint white mist appear at the top of the stairs.
My next experience was about five years ago when I was waking up a lot at night and not being able to fall back asleep. I kept thinking it was just my imagination, but I kept hearing footsteps in my living room downstairs. Occasionally, it sounded like my dogs were playing with someone. They were puppies at the time and they were very good at sleeping during the night. I even remember one of dogs kept barking and when I went downstairs to see what her problem was, I swear I heard someone walking behind me and breathing heavily.
About a year or two ago, I started sleeping in the attic. I was still waking up a lot, and normally at the same times. I remember that at approximately 3AM, never later than 3:05, I would hear footsteps on my stairs. They're old squeaky wood steps, and you can hear every step on them. For a long time I convinced myself that it was just the wood settling, but I started to notice that it was the same time every night. Other times during the night, I would see shadows moving out of the corner of my eye.
There have even been times during the day that I would experience things in the attic. Things would move, the light in my closet would turn on, and silence would be broken by sounds I couldn't explain.
