Speaking of which.... lastnight I was convinced that the ceiing was cracked and that the light fixture was dancing like a flame.

Ha, I remembered that my ceiling is just fine and reminded myself that the light fixture couldn't move. So I ignored it.
Uhm, in my limited experience with pdocs, the moment you mention it, they up the meds or add an AP if you're not on 1 already. And I'm sorry but from my angle its just not worth it if it doesn't cause any distress or pose any danger to your reality.
If it is distressing, then definitly mention it.
