Is there an "uncanny valley" for sounds?

Because, there's a distinctly -odd-...something...that's only audible in the bedroom, these last couple of nights. At first I was convinced that someone was playing the TV or the radio, because it sounded just enough like the rising and falling patterns of speech, with appropriate pauses, but--maddeningly!--just low enough to not be able to make out what was being said, or even what language.

Then I tried to figure out where it might be coming from, since at four in the morning it was getting a bit old. So I tracked it to where I -thought- it was coming out of--sure enough, someone on the floor above playing what sounded like the news in a foreign language, loud enough to be heard through the front door. I knocked and asked her politely to turn it down. She apologized and did. I went back home. No change.

So then I figure it must be the pipes or the radiator, after all. It's wintertime, or nearly, old buildings make a lot of weird sounds as they creak into warmth.

Except...I can hear the pipes. It's -not- the same sounds. They're going right now. They don't sound like that. And, I never hear that particular sound in the rest of the apartment, or during the daytime, like now. Only in the bedroom. At night. In the dark.

i'm sure it's nothing really

And no, it is not a steady pound-pounding coming from somewhere beneath the floorboards.
I'm fine.

That yellow wallpaper's really got to go, though.
