A bedroom mirror near the door should be assessed for sightlines, safe mounting, night-time reflections, storage access, and walking clearance.
Quick answer
There is no universal ban on a mirror facing a bedroom door; adjust it when the reflection is distracting, startling, or physically unsafe.
Check what the mirror reflects
Stand at the doorway, on both sides of the bed, and at night. A bright hallway, cluttered rack, or moving door may be more disruptive than the compass direction.
Protect circulation and mounting
Do not narrow the route or place fragile glass where a handle can strike it. Tall mirrors need secure fixing appropriate to the wall and household.
Use small corrections first
Rotate the mirror, move it inside a wardrobe, soften the reflected light, or change the door stop. Keep a change only when it improves comfort and function.
