I was a teenager at the time and was leaving my best friends house which was only a few blocks away. We lived out in a rural desert area by the base of a mountain, and when it got dark it got dark and eerie sometimes. It was an odd night in which my parents actually let me stay out late, they never let me stay out late. Anyways it had gotten late, and I was driving back home. To get to my house I had to go up a small dirt hill. As I'm going up the hill, my lights hit this tall shadow, that is shaped like a person. I get chills immediately and stop my car, the shadow just stands there and we are still for what felt like forever. Out of nowhere the shadow starts moving really fast towards my car. The shadow figure never gains a human features as it's gets closer it continues to be a tall shadow. I get scared and hit the gas and start speeding up the hill towards the shadow. I kid you not, as my car reaches the shadow, it in matrix like way just slowly walks onto my car hood, onto the roof and then jumps down and lands behind my car. I hit the breaks, and look back and it's staring at me, I couldn't see it's eyes but I knew it was staring at me. I hit the gas again and book it home. Immediately running in doors but feeling like it was behind me the whole time.
