What does it sound like when you hear your eyes move?

This probably sounds stupid, but I'm in my 40s and didn't realize until recently, when my ENT asked if I hear internal body noises, that most people don't internally hear themselves breathing at night. Now I'm questioning other noises.

I recently had a stapedectomy to fix otosclerosis, but my hearing didn't return as much as expected and I'm having other symptoms that have gotten me scheduled for a CT scan this month, because the ENT suspects SCDS.

When I move my eyes to the far left/right/top/bottom, it makes my ears "thunder", almost the same as when I wiggle or tense my ears.

Am I hearing my eyes? What does it sound like to you?
