This series of events happened somewhere in Silang, Cavite, Philippines while I was working there over 5 years ago. The place where I worked is called the Campus by insiders. It has a proper, official-sounding name of course but that is what we all call it. It made us feel, well, insiders. Besides, it's shorter.
In the early 90's, pioneers hacked, hewed and chopped out a clearing in the forest. With only a few army tents as shelters, they started operations of the Campus. It is about 500 meters away from Aguinaldo Highway, across a wooden bridge that spans a narrow creek. Coffee trees line the last 20 meters or so of the road leading to the front (and only) gate. It's not really secluded because there is a small community along the road, and it's only about 20 minutes by car along the highway to Tagaytay and about 10 minutes to Silang Proper going the other way.
When I got there more than a decade later to take up my position as the resident IT guy, the army tents were replaced by concrete buildings with manicured lawns and landscaping. But the same forest still surrounded its three sides, held at bay by a 15-ft wall. It's a pity that the wall could only keep out the trees because it sure let's in other things that I could describe only as supernatural.
For one, there is the lady in white who likes to take a stroll in the garden in the middle of the campus just before or after midnight. I haven't seen her myself during my whole stay but a lot of people did, including one woman whom I really admire for her honesty.
There is another entity which took up residence in the motor pool. They say that this one likes to make noise at night by banging on the steel grills that served as walls on two sides of the building, so I decided to check this one out personally. In the motor pool is an upstairs room with several bunk beds where the mechanics and drivers are housed. I requested from the residents that I stay there for the night, to confirm for myself the existence of the resident poltergeist, and I was made more than welcome.
