Closed almost all the way, but not shut. Need that air circulation otherwise the room gets too hot

Closed as I don't really want my roommates to check in on me sleeping

Open, because kids.

Open to get some air exchange

Open a crack so the cat doesn't wake me up at 4am.

Closed. The missus and I can be... active at times, and we have nocturnal teenagers.

Open, because I have a split AC in the living room of my bungalow and the bedrooms get warm even with the doors open. Also the dog and cat would never allow a closed door, and they rule this roost.

Bed room door closed, but usually not locked. 8 sentry turrets have the outer perimeter of the house secured. /s

I removed the door from the bedroom, so 'open', I guess.

Closed. Otherwise dog sneaks in, climbs up on the bed and falls asleep. The he slowly but surely takes over the whole bed.

Always fully open! More airflow, less stuffiness. Having said that, we don’t share a home with anyone else.

I prefer open, but I got a cat a few months ago that won’t leave me alone if I leave it open. So, closed.

Closed, I already have scars from our cat's mad night escapades.

closed except cat so always open now :(

Prefer closed, but like many others here, the cat doesn’t allow for that without making her opinion VERY well known.

Sleeping in the house's veranda, so no doors 😶‍🌫️

Open. I live alone and I have a cat that comes and goes throughout the night. Having the door opened allows me to hear anything that should not be going on in the house.

We have a saying in our house... "ghosts" that means close the door we are going to sleep and don't want to let the ghosts in. Closed. Always closed.

Door closed, window open.

Closed and locked. (Trauma likely)

Closed. I prefer my door closed for privacy reasons, so why would I keep it open when I sleep?

Open because pets

Closed and locked. Open doors in the dark are creepy. Besides I want some privacy for certain "tasks".

Closed, i don't like mosquitoes.

I live on my own so all the doors in the flat are open all the time, even the bathroom ones.

Greatly prefer it closed, but leave it cracked for the kitty.

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.

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

Depends on the outside temperature.

If it's warm outside, all my flat's windows are open and for better airflow I leave all doors open, too.

If it's cold outside, everything is closed to retain the heat in my bedroom.

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

Closed. My housemate's cats sometimes pounce onto my bed and wake me up.

The closed door also dampens outside noise.
