Before moving to our forever home, my family lived in a haunted duplex. Doors would open/close, strange noises coming from weird places, etc. Nothing malevolent, just off putting. Even the dogs were effected by it at times.
There was a bonus room upstairs that became my music room. That room was weird. Lights would turn on and off, hanging speaker cables would seem to dance along with my drumming. Sometimes I would go upstairs and get a very creepy feeling like the room didnt want me there and I wanted to go back downstairs. Again, nothing malevolent.
I found out about 2 years in that a little girl had died in the building like 20 years earlier. My guess is she still lives there.
