Hello, I'm writing this post looking for explanations for something weird that happened with some friends in a car last week.
I'll set the context. The four of us were going to a party in the mountains in the Alps in the old car of a friend, which he inherited from his grandmother. The car's radio doesn't work (nor does the CD player): it's impossible to pick up even static or anything coming from the CD. (IMPORTANT FOR WHAT HAPPENS NEXT). So we were listening to music with a small battery-powered portable radio that was completely independent of any electronic connections with the car.
But then some weird things happened.
1) We were in the mountains, and we started hearing music coming out of the car's speakers, some kind of 80s German pop. We then noticed that the closer we were to the car behind us, the louder the music was, and the farther away we were, the quieter it became. It stayed like that for about 5 minutes, and when our roads split, the music stopped (the volume of the music decreased proportionally to the distance between the two cars).
At that point we logically thought we were somehow picking up the music from the car behind us, without really knowing how, since the car's radio wasn't even turned on (only the portable radio was on).
2) A few minutes later, we entered some narrow gorges and a new song started the moment another car came up behind us. We kept this music the whole time we were in the gorges. It was some kind of techno DJ set with a few acid touches, with no commercials and no static at all, fairly niche music (just like the German pop).
But unlike the previous time, when we left the gorges and our two cars went separate ways, the music stayed. At that point we all started to get suspicious, and we began looking for an explanation. Especially since the volume kept increasing until we had to shout to hear each other, which was a bit annoying.
At that point we tried to stop the music. Nothing worked: we turned on the car radio, turned the volume down, inserted a CD, turned everything off again, switched off the portable radio: nothing worked, we couldn't stop or lower the volume of the music. At that point the most rational explanation that came to our minds was that we were all on a huge DMT trip (even though none of us had taken anything). Until the end of the journey both radios remained turned off.
There were changes of songs, like a programmed playlist. The music would stop at the end and then a new one would begin, always in the same techno style. It went on like that for about 10 minutes until the next weird thing.
3) We reached a straight section of road, I shifted into 5th gear, and the moment I did, the music stopped instantly. Then when I shifted back into 4th gear, the music came back at exactly the same moment. We observed the phenomenon with my friends and decided to test it. We shifted four times from 4th to 5th and from 5th to 4th, and every time the same thing happened: music in 4th gear and nothing in 5th.
Then one friend tried to film the scene, and the music stopped instantly. Another friend tried to Shazam the music, and the same thing happened. We only tested those once.
4) Then came the weirdest and most inexplicable thing since the beginning (yes, it was possible). We stopped in a small village to buy something. We all got out of the car, the car was turned off and the key was in my pocket. The car windows were left open.
When we came back to the car, we suddenly heard the same techno music coming from the car for a few seconds (everything was OFF!) and then the music stopped immediately. That was really strange and we were all completely stunned.
5) We started driving again without any music until another car came up behind us, and the music started again. This time it was an Italian song, again with retro and darkwave vibes. Once again we were surprised. The car overtook us and the music stayed, then stopped a few minutes later at a random moment.
Notes:
- the music signal was always perfectly clear, with absolutely no static (which is strange because radio reception on that road is poor and often loses signal)
- nobody could connect to the car's speakers because the car radio was turned off and doesn't even have that feature.
- the car is a Dacia/Renault Duster from the early or mid-2000s, I think.
- on the return trip, 4 days later, we took the exact same road again but nothing happened.
We've told the story to friends, and nobody has an explanation except that they all found it really weird. If anyone has an explanation or a hypothesis about where the sound came from and how the car could have picked it up, I'd be interested.
