No, and I live with people. The real reason behind this is that, well, how to put this... my cat has needs during night time and because she loves me so much (actually a loving cat, not the bossy type one) she sleeps with me, although she has the whole apartment at her disposal
What I prefer is moot as if I leave the door open I will be sleeping with 6 cats either on top of me or under the covers. I'd keep the door closed either way (I prefer it to be really dark and quiet in my room), but especially now with all the kitties.
Me door is always open, well, I can't close it, but it's okay like that, I have some claustrophobia, not that bad, but well everything must be open apart from the door downstairs 'cause of the tv sound. Some of my cats open it, but they don't close it sadly...
I generally close it but there have been times where I've attempted to get over my obsessive need to have it closed and left it open, or the cats would open it at night etc.. I always find myself getting up in the middle of the night to close the door though.
Lol i leave my door closed, but my cat, she comes in under the door, as fat as she is lol. Sometimes when i wake up she scarez me because i dont know when she comes in. My room is dark all the time, because i put blankets over my windoes. Shes black cat too, so sometimes its like "wtf is that black figure?" And the light bulb broke in my room, so oh noez
Closed door. I would probably close it even if I would be alone in a house. Except if the room would be too cold and the temperature would be better on the other side of the door. It happened once (not at home) that I left the bedroom and slept next to a tile stove.
