Yes. In a way. Every so often I get ringing in my left ear. It doesn't sound like anything familiar though, so I have always taken it as a quirk of the ear.

I do hear things on the verge of waking that do no compute with what I see once fully awake. Sounds that, after a little thought, made no sense at all. The circular part is that I feel like it's the sound that woke up me up with which to begin.
