Mysterious Figure - Kajang Highway

I was with my ex, K, 5 years ago...we're on our way back to Kajang...when we're half way on our way, K stop the car and pull me out. I thought K is gonna dump me at the highway, lolz... but no, K pulled me and run away from the car...

We ran quite far away before i struggle off and stop...
L: What happen?
K is still breathing hard...
L: What is it baby?
K: I saw something behind...
L: What?

As i look back at the car, i saw a head at the back of the car... but i can't really confirm whether it is a head or wat...coz its kinda dark and we're so far away... I told K i wanna go back and have a look but K pulled me back... It was 4am, come on...i'm fucking cold and i dun wanna stand there whole night... at last, we saw a motorcyclist. The indian guy stopped by and ask whether we need help or not... after we told him about it, the indian guy warned us not to stay at here too long as there's a lot of fatal incident happened at there b4...

Nothing we can do much, I took K's hand and promise i will take care of it... we walk towards the car, the mysterious figure was gone...i swear it is gone...coz frm the black thing which i saw jst now was no more at there...then we hopped in the car and drove away...

how true is it? i dunknw...but i knw i saw some black thing like a head... but is it shadow? is it becoz of dark? i'm really not sure...
