These experiences happened when my daughter and I lived alone in an old house owned by a friend of my mother. Sarah wasn't much more than a toddler and I was heavily pregnant with my son. His father and I were technically together but we were still living separately until we could find a place to suit us.
Sarah and I slept in the biggest bedroom, me with my bed and her in her crib. That room stayed cold, so cold I asked my dad to check the heating (it was an ancient heating system) but he found nothing wrong. So I blamed it on the huge windows in the room.
After a couple weeks, Sarah started screaming whenever she was left in that room alone and my bed collapsed 2 or 3 nights in a row so I gave up and we slept on the couch together.
Well, the next development was whenever I got up in the mornings, the bedroom door would be locked from the inside. I started keeping a butter knife on hand to pick the extremely old lock whenever I needed in the room.
Apparently after these tricks got no big response from me, it resorted to messing with my daughter's porcelain doll collection. In one of my previous stories I mentioned an aunt with a love for flea markets so Sarah had a large collection of antique dolls arranged on a built-in shelf in that bedroom. Every morning after picking the lock to gain entrance to my own bedroom the dolls would be rearranged and turned to face the wall. Ok, no big deal, it's just irritating, so I continued to ignore it.
Another notable experience while living there was one night I got up to pee, not unusual considering I was pregnant and peed on average once an hour, lol. The bathroom and the dining room share a wall, so I was sitting there half-awake and suddenly heard whistling clearly from the dining room. About the time I registered the whistling it turned into a tune that I still can't quite place. It lasted for long enough for me to be certain that yes, I was fully awake by then, and yes, it was a tune before it stopped.
We moved after my son's father and I found our own place, not because I was scared. It never bothered me and actually made life a bit more interesting!
As for the history of the house, all I know is that my mom's friend's family bought the large amount of land it was part of to build a new home and decided to rent out that little old house instead of tearing it down. It's still there and I wonder if it's still occupied by my whistling friend!
