Real life audial hallucinations

[Boogus Epirus Aurelius]

I had supposedly invited a few people over for tonight a while ago and they called me with ten minutes to spare before they did.
Show up, that is.

So, I made some fettuchini alfredo with some leftover chicken I had in the fridge.
It was easy and delicious.
So, we had a handful of quick "how's it going" drinks and reminiscence dialogues and they left rather early.

As a result, I keep hearing this sound, like a referee's whistle with a ton of reverb on it every once in a while.

It's not my computer and it's not my television.

Let's hunt for boognish's mystery sound.

plug your ears. do you still hear it?

It's so sporadic. When I try to listen for it, I don't hear it.

let's hope it isn't a friend's forgotten mobile
