I may have almost gotten kidnapped when I was 16. It was quite an odd creepy experience. I was riding my bike on a trail that goes alongside the rode near my house, and there was a red van with tinted windows driving strangely. It was weaving from side to side (even into the other lane), randomly speeding ahead and pulling off the side of the rode and stopping for a few seconds, and the rest of the time just rolling along very slowly. I thought the driver might be drunk or something, so I stayed on the far right side of the path and kept an eye on the car, making sure not to get close in case he decided to drive off the road. Behind the van was another car, driving normally. Eventually the normal car passed the van, sped a good ways ahead and pulled over on the side of the road. An old guy got out of the normal car, and started waving his arms and yelling "Are you alright!?". I thought he was yelling to the van at first, because they were just not driving right at all. Once I got closer, I realized he was yelling to me. I stopped when I got near him (Dumb I know, but there was a good amount of space between the road and the trail, 20 or more feet, plus he kept his hands visible the whole time and never tried to get even a step closer to me)
Old guy: Are you alright!?
Me: Um... Yeah...? Why do you ask?
Old guy: Do you know that car? *points to van, which is just sitting creepily on the road*
Me: No. Why?
Old guy: Because it's following you. I called the police. Do you need any help?!
Me, going into nervous suspicious mode: I think I'll be alright, I'll go to that golf couse until the car is gone. Thank you very much, though. (We were right across the street from a crowed driving range)
Old guy: ...Alright. Be careful.
I thanked the old guy, he got in his car, and drove away.
I was about to cross the street to the driving range, when the creepy van rolled up ( so I backed away from the road) and stopped right in front of me. I was just waiting to hear a door click to run yelling to the driving range. The passenger side window rolled down, revealing the driver to be a obese, wrinkly woman (kinda looked like a tuskless walrus)
Walrus Lady: What did he want?
Me, lying: He thought there was something wrong with my bike, but its fine.
Walrus Lady chuckles while doing the creepiest smile I've ever seen: Don't stop for anyone...
Walrus Lady drives away slowly. I watched until she was out of sight, to make sure she hadn't turned somewhere to wait, and went straight home.
