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

Open to get some air exchange

Closed because I am a mammal and I indulge in the nesting instinct.

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

Door closed, but windows open and fan on

closed door because roomates, but open balcony door for maximum fresh air and feels of nature.

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

Closed, safer when fire

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 except cat so always open now :(

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

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.

Closed, i don't like mosquitoes.

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

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 and locked. (Trauma likely)

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

Open because pets

Sleeping with the door open should be a crime

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.

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.

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

Door closed, window open.

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

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, 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.

Open for air circulation. My fiancee and I live in a too-small, old apartment which, naturally, has trash airflow. Getting the AC to decently reach the bedroom requires multiple fans.

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

The closed door also dampens outside noise.

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

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