i was sitting in a car with some mates while back, we turned on the radio and between stations we heard this weird sound seemed like people talking but we couldnt really understand jack of it, not even which language it was, and the only radio stations u can pick up here is like from the netherlands, france germany and sometimes the uk, but it wasnt any of these languages and it was pretty clear we heard it for about 40 seconds. it made me think about the weird sound in this movie, probally was nothing but it was still pretty weird
