my personal experience.....one of the high rise office building at mutiara damansara
around 8 something, in office, working.....windows all closed, air-con shut down at 5pm, but, still not too warm.....suddenly photo frame (those small one, put on table) jatuh, I mean, really jatuh, not slip, dunno how to explain, if slip, the photo face upwards, this one photo face downwards....confirm no wind, nobody around, only me and my colleague working......which is 5m away from it (we both sit next table). I cool only put back the photo, buat dunno, no scared, that time dunno mar, also, got members
second incident, same building, different floor, again, work late, 8 something, also got colleague, this time, lagi geng, the whole white board (not big one lah, just about 1m size only) jatuh from cupboard....if say slip, not possible, coz we put in slight angle, then, use a small flower pot to block it. This one, flower pot intact on cupboard, but, the whiteboard on the floor.....this one, bit takut jor.....slowly, quietly, say sorry in heart, pack and cabut....
third time, same building oso, same floor, again, work late, around 11pm, alone, very sure I am alone in the whole floor, then, got sound like ppl typing keyboard, putting pen in penholder/ cup, making drinks, etc.....machem someone still working lah or normal working time....confirm no one, coz earlier the guard got round oledi, he off lights on those section no ppl one, only left my section and pantry. Can feel something jor.......but, because really rushing something, really rush.....silently say in heart, "please lah, tolong lah, don't kacau me, I am rushing something, let me finished my stuff asap then I will cabut lah, sorry lah......I will leave asap, immediately after I finished", dunno ghost know what language, I use whatever language I know

....maybe the fella pity me, no more kacau jor....no more sound.....and, I quickly finished my work, cabut, kept my promise.....
Later found out that place, the building is located is actually used to be orang asli cemetery area.....
One last incident, same building oso....work late alone oso, same situation, got sound, as if someone working, but, I am absolutely sure I am alone (coz earlier another colleague thought no one jor, go off all lights, I shouted "OOOIIIII".....the fella terkejut, say sorry, on back the lights

), then, after dunno how long, quite some time lah after he left, I no pay attention, I concentrate working, want go back earlier, before "they" come halau and kacau, But, too bad, kacau again, this time, even worst, as if like very curious with what i do, why i stay late, or why usually me stay back, coming closer and closer, can feel jor.....since my back is facing walkway, can't see, don't dare to see oso, in my heart, i silently say the same thing oso, ask don't kacau, don't disturb, will go back asap once finished, but, this time no effect.....since I am not that holy oso, whatever chant, god name i call oso no help......last last, I remember got one Guai Tham episode, the sifu say, if u got no religion, nothing can help, last resort, you shout lah, scold lah, scared them back....not advisable, very rude, but at last resort lah.....hope they scared and run away, instead of angry......so, I pun start shouting and scolding, with all obscene, vulgar words I can think off, in all whatever language I know, cursing all the fella ancestors and future generations

shouting......hope the fella will back off........true enough the fella back off, and reply me "Apa nie" (I scared mar, no turn back look), I turn back, actually was the guard ronda

for buta buta he got scolded by me, lucky no use the baton to hit my head

...but, from that day onwards, whenever the guard ronda, the first thing he enter the floor, he will shout, "ALLOOO....ANYBODY.....ALLLO....GUARD RONDA"
