Part 1.
Circa 2005.

The old IBM building at TTDI,now VADS.
When my company conducts a DRP exercise, it will usually last for a week.
The network, database and system guys will be camping at IBM building, and working till late nites.

Me and my DBA was the last one to go on our last day. The IBM guy had already left at 5pm and its now around 9.30pm. Very quiet. The toilet at this floor is right at the end of all the computer and server room.

When I was about to pee, all of the toilet started to flush by itself. As I recalled, the toilets are all the old school, non electronic types. Then I heard someone coming in, the toilet door open and I thought it was my friend. I finished my business, and check, nobody was inside. Fine.

As I walked back to the server room, every footstep I made, I could hear someone behind me. Fxxx it.

When I arrived at the server room, I asked my buddy, did he went to the toilet and his answer was no. Fine. Maybe it was my imagination.

We both continued with our work. It was around 10.30pm, and we were both focus on our work,when we heard a screeching sound. We both look at each other. I open the door, and we look it was coming from the end of the hall way leading to the toilet. Then, a noise of footsteps.

Thinking that we needed to complete our work since its the last day of the DRP exercise, we closed the server room door and just went back to our consoles. Then we heard tapping on our door,and nobody was at the door.

My friend blurted, 'fxxx you, Im trying to finish my work ok'. That tapping sound became more louder. So, ok fine. I guess what ever it was didn't want us there.We logged off and just left. I told my buddy lets get the other stuff tomorrow.

Next morning we arrive, we told the Administrator what happen last nite.
So he told us that the building is haunted. A depressed lady came up the building one day, after 7pm and jumped off.
