Way back 2007, I worked at the 7th Floor, MCC Steel Corporation as a Purchasing Assistant for about a week. Since the building is very old, I have heard so many stories about the ghost who haunts the whole department. On the third day of my work, during lunchtime I went to the Comfort Room, it was big and it has 4 cubicles. I chose the fourth cubicle. The moment I closed the door, I heard a FLUSH coming from the first cubicle.
It was really weird because I haven't seen anyone who entered the CR with me. Besides, if someone entered right after me, I would hear the door opens because it was really heavy. So, I went out and checked the first cubicle and no one was there, the scary part was, when I saw the water from the toilet bowl drained down like if someone FLUSHED the toilet. It scared the hell out of me and I ran as fast as I could. After that incident, I never went to the Comfort Room on that floor. This was one of the reasons why I quit the job.
My officemates told me that the 7th floor specially the Comfort Room was haunted by a ghost lady. Some employees including me saw a blood on the water tank. Even the reliance of the building was scared every time she went to the 7th floor and cleans the whole area. She said that she heard so many things and you would have a very eerie feeling when you're alone on that floor, even daytime. We were not really sure what is the reason behind all the haunting. All I know is I don't want to go back there!
