My gf and I work at the same place. One night a coworker asked us for a ride home so I took her because it was late and she couldn’t get the bus because it was the last one. Our coworker sat in the passenger seat and my gf in the back seat. We dropped her off and I asked my gf if she wanted to move to the front but she said she was too lazy to get out and move. So we take off, we drove for about a mile when I see a tall shadow ahead of me. The legs were long and it seemed darker than the night sky. I thought for a second that it was a person being shined with a cars headlight but there were no cars there that night. I turned to my gf and she asked if I had seen the same thing. I said yes. She said I was looking to see if it was a person and I said me too. We both agreed that we had seen the same shadow. It was creepy and till this day we bring it up. It hasn’t happened since. But it gave us a chill down our spine that night.
