When I first moved to the city, I lived in a basement apartment. Got used to all sorts of noises. Cats copulating was the main disturbance

But the one I didnt understand was a weird hollow moaning sounds. No one lived above me at the time and it wasnt wind tunneling.
And my current apartment is haunted with lord knows who. It's an old building.
I hear random creeks, doors swoosh without any wind. The first year, I heard a lot of mumbling coming from my fire escape but no one would be out there on any of the floors.
It's died down. I think whatever ghost lives here feels bad because I spook easily o.o so it hasnt done much lately.
