Usually closed because I like to be naked, but I would prefer it open for the pets to come and go as they please.

Open because pets

Both, because I'm lazy. Whatever the door is at is how it will stay.

Closed, air-conditioning is expensive. When me and my wife travel to colder areas we do tend to sleep with doors open though but it highly depends on the house itself. There has to be a certain vibe or fenshui so to speak where open door feels pleasant and not this uncertainty.

I am staying in a men's hostel. Cheaper that way as I am single. It is so hot here during summer. So we keep the door open at night. Three of us are there in the room. Everyone is ok with that.

I want it closed, but the dog wants it open and his litter box is in the hallway. So, open it is.

Closed because I’m afraid of the dark most times. My cats don’t care they run around the living room. Dog sleeps with me on the floor at the bed to protect me.

Closed. Like to keep my room temperature like 10°C lower the rest of the house during the night

Open but I live alone in a small 1 bedroom apartment. Mostly so I can shuffle to the bathroom in the night if needed without needing to open the door

Closed, keeps the dogs in so they don't leave us a surprise.

Open both for airflow and because we have animals that do not like to be restricted.

Open. The decline of the political climate in this country since 2001 has made me fear for my safety since I was in middle school, so keeping the door open helps satisfy that part of my brain that's always in threat detection mode by allowing me to hear everything in the house from my bed.

Plus, I live alone. So pretty much every door is open all the time.

Cracked open so we can hear across the house to our kids room (also cracked open)… baby gates in front of both rooms to prevent the cats from disturbing our sleep lol

I keep mine closed but not latched so the dogs can open it in the morning otherwise they sit outside and scratch and wake us up.

Window open, door closed; window closed, door open. I do what I can to prevent unnecessary door slamming in the night caused by a draft from the window

Open - just me and my husband here and it keeps the room cooler.

Closed, because I don't wanna be snuck on.

closed

Open in summer, for ventilation. In winter it stays closed to let the bedroom be chilly, without affecting the rest of the place.

Don't have a door but a stair. Don't need a door cause I'm the king of the castle

All depends on whether you live with other people or not. If others can be in the house making noise then door closed. If you live alone then it doesn’t matter.

I don't have a door

Open when I was at my house. Closed as I'm renting an apartment now with several flatmates.
