DAE got genuinely traumatized or creeped out by a specific sound ?

I'm currently doing some research into creepy and weird sounds, and it made me think about my own experience. Personally, I've always been terrified of sirens. I live in France, and on the first Wednesday of every month at noon, they test the public alert system sirens. That sound always triggers a bit of anxiety for me.

Does anyone else have a specific sound that deeply bothers or traumatized them?

Thank for your answers :3
