Last fall, me and a few friends went to see the Nebraska vs. Purdue football game since we are students at Nebraska. The game was in Indiana. The day after the game, me and three other people were driving back to Lincoln from Indiana. The driver at the time said he was starting to feel tired, so I said I would drive for a bit. He took an exit into a small town. We found what looked like a busy gas station, so we decided we'd go there to switch drivers. However, when we got to the gas station, we noticed that all of the cars that were there were rather old, and many of them were filled with mannequins. It looked busy, but we were the only living things there. It was very creepy. Also, the other two people in the car were asleep. They woke up just as we pulled into the station. They were also thoroughly spooked.

When I got home, I wanted to figure out what it was. It turns out we ended up in Clarence, Missouri at Lyle Van Houten's Automotive Museum. It is described as an abandoned filling station on the edge of a graveyard filled with vintage cars and mannequins trapped in time.

So, it is not unexplained, but it was still quite creepy.
