Is it normal to sleep with the door open?
Yep.Totally normal
Yes, it’s normal to sleep with the door open. It mostly comes down to comfort, privacy, and who else is in the home.
Some people like the extra airflow or want to hear what’s going on; others prefer a closed door for privacy, quiet, or a cozier feeling. There’s no one right way to sleep, and plenty of people do either.
If you share your home, it’s worth making sure everyone’s comfortable with the setup—especially if pets or roommates might wander in. Otherwise, leave it open if that’s what helps you sleep.
