A window in my house faces the bedroom door. Isn't feng shui good?

There are many considerations about the quality of feng shui, but from what you said, it won't have any impact. Doors have an impact on doors because they are all entrances and exits, and the air conflicts. But windows are mainly used to disperse air, unlike doors, which will have no influence. It's just that if there is only one window in that room, and it opens inward, it will not be conducive to ventilation to disperse the dirty air, and it will also have a little impact on the room facing the door. Secondly, outsiders often pass by the window, which will interfere with the people in the room and often have the psychological feeling of being peeped.
