Do you associate any specific sounds with something unexpected or unusual?

For example, locusts always make me think of sweltering hot weather… and the end of the world. Maybe not completely unexpected, but something about their sound makes the day feel so much hotter than it is. I assume this is because they always chirp (?) in the dead of summer, and I have made a mental connection of the two. The end of the world correlation is self-explanatory, but the sound really does make sense to me. It’s eerie.

YES, I am still on the subject of creepy crawlies.

Are there any sounds that you associate with something that others may not make the same connection? Do you know why that is, or is it just a random development?
