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

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

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

Open, because kids.

Open to get some air exchange

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.

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

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

closed except cat so always open now :(

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

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

Closed and locked. (Trauma likely)

Door closed, window open.

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

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.

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

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.

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.

When sleeping, me close door

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.

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

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

Open because pets

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

The closed door also dampens outside noise.

Closed, i don't like mosquitoes.
