Okay here it goes. This happened not far back. I think it was about earlier this year or last year. I can't remember, but this is how it goes. My wifes friend had lepak at Hartamas till somewhere around 3-4am in the morning.

He drove home heading to K.L via the 'shortcut' way, the road that heads to Masjid Wilayah after the Hartamas traffic light. So he passes by all those rich folks houses, passes masjid wilayah until the connected highway.  He drives along the flyover (not on it) to the traffic light before the Kuantan/Batu Cave exit. So what happened was before he arrived to the traffic light, he saw some dude, powerwalking (jalan laju like the sports one) on the road.

He was curious at first as but it didn't feel weird enough from him. Maybe the dude just liked to exercise at night. The shtty thing was, just as soon as he arrived at the traffic light, the damned thing was beside his car, doing some stretching/ cooling down movements (rotating hands, and circular motion of head). Now that freaked the sht of him.

The thing then slowly turned it's head towards my friend, who pretended not to notice it. As soon as the traffic light was green, he sped off, only realising as soon as he looked at the rear view mirror, the damned thing was sitting at the back seat of his car!!!!!!!!!!! This scared the monkeys piss out of him but he didn't want to drive it back home to his place. What he did next was drive around with the thing in his car until it was almost Subuh. As soon as it was almost Subuh, he drove towards masjid Wilayah.
After the Subuh azan, the thing dissapeared from his car and he headed home.

And yes, I do get scared using the 'shortcut' everytime i think of the story.
