Open, so I can see and hear out.

open, I need the connection to the rest of the world.

Open because of the damn cat. We love her though.

Door closed, all the time. In case a cat gets in. But I’ve always slept with the door shut, in case monsters get in.

Door half open so the cats can walk back and forth, but not so much that it’s too light in the morning.

Open but these fire comments have me reevaluating

Open. If my kids need help and call out in the middle of the night, I would like to hear them!

Winter: Closed. It can get to -25C where I live, and I need to sleep with the window open. I don't want the rest of my house ruined with the door open.

Summer: depends on the heat. If OK, closed. If too hot, door ajar

Door open if it's hot, usually with the fan pointing out the door. If it's REALLY hot, fan directly on me.

Depends, if it's hot enough to need the AC, door closed. If not, door open so I can open the window and get some airflow.

Open, lets the air circulate better

I keep mine slightly open and make sure there is a window open in my room and in another room to create a breeze

Closed in the winter, Open most of the summer so that the whole house fan can pull air in and through the bedroom cooling things down.

Closed, because fire... https://youtu.be/PYvF5oxSXZc

Open to keep the Monsters out, closed to keep the Monsters in.

Closed cause I don't want to deal with people walking around late at night with lights on or the cats waking me up.

Open. I want to hear if anything happens in my house.

Fire vs CO2 buildup. I guess door closed, window open could be the way?

I prefer closed, but since our cat moved in, the door has been left ajar.

Ajar

Closed, because of cats.

Oh and also for fire safety, I guess.

closed unless it's hot. closed gives me privacy and quiet and makes it darker, but if it's too hot having it open gives me better airflow.
