Did you see Monster INC? When they opened a door to the children's
bedrooms they can see inside this room when looking from the one side
of the door but walking around the door shows what is real behind the
door which is the room the door is standing in.
Usually it is done by setting the door as portal where viewing is
clipped on that portal so that objects connected to that portal are
only seen thru that portal and are also clipped on it so you'll never
see objects outside that portal.
