I lived in a dormitory building for two years in college. Everyone in my building would joke that our old elevators were being haunted by Victoria, the resident ghost, mainly because the elevators would randomly go up and down the building, stopping and opening at random floors with nobody in them.
I laughed it off, not really believing it. I also heard stories from my floormates and others living there hearing a female voice. I brushed that off too, until one fateful day. I was in the basement laundry room taking care of my clothes when I heard a voice, clear as day, say “Hello?” as if answering a phone call nervously.
