I have recently changed jobs but before that happened, I was working at this place for about 3 and a half years. Now, I have heard a lot of stories about the building I worked in and they haven't been very nice, for instance, it used to be a farm run by a man who supposedly killed and tortured people, now I'm a bit of a skeptic when it comes to things like this, that was until about 6 months before I left, when two incidents happened I wish to never experience again.
I was walking through a hallway that leads into another room that we used for storage and it has two doors and the floor itself is tiled so it's easy to hear both the doors open and anyone who happens to walk across the room. This was at about 5pm, I heard what sounded like a man quietly talking to himself and then followed by very loud footsteps, bear in mind that I would have been able to hear the doors open, but there wasn't any sound of any doors before or after it happened.
The other incident I was walking through the same hallway, but this time I happened to see what looked like a tall dark outline of a person standing in the corner of a small room that links up to the hallway. I stopped and looked back into the room and I saw the figure still standing there but without any legs. Now I have heard stories that ghosts are not there to hurt people but this was a different case, the figure that I was staring at suddenly rushed towards me, followed by a faint but harrowing sound of someone screaming like they are in horrible pain.
Skepticism is no longer an issue for me as this was an experience I never wish to encounter ever again.
