Those of you with bathrooms attached to your bedroom, do you normally keep the door open or closed while you sleep and what's your reasoning?

To me it shouldn't matter, but it feels weird having the bathroom door open all the time. Also my shower sometimes does a midnight clunk for no obvious reason and it's loud.

I never really thought about it until now, since I've never lived in a "master bedroom" with attached bathroom until now. Still on the fence, leaning towards keeping it open for convenience and airflow/dehumidification more than anything. Obviously I shut it after things get smelly.
