Growing up, I lived in a fairly old (I’m assuming), kinda weirdly laid out house. It had it’s usual sort of symphony you find in places like this, creaking of the wood expanding and depressing, rumbly pipes when in use, that sort of thing. However, from time to time, we’d hear or see something a little more dubious: footsteps up and down a hallway or a figure lingering at the corner of your eye. My whole family has various creepy stories that came from that house. Nothing exceptionally aggressive or crazy, just creepy stuff. Very subtle things.
