In recent memory.
My father is playing old forties music. The choir sounded like air sirens and it reminded me of those movie scenes where the nuke is falling with the sirens and everybody is screaming and the song is just playing and I freaked the fuck out like I thought it was real and I shat a little bit. .-.
Which reminded me that for some reason, at like, seven in the morning one day, i just heard a loud fucking BANG. Like, I woke up and my ears were ringing and it hurt. Really loud.
