Doorways

"The first way," explains Beatrice, "is to locate the door which is the opposite of the one you came in through."

Beatrice continues..."The door you came through was an entry door. It goes only one way. You must find the Exit door which leads back to your world. It will look exactly like the one you entered through. However, this is not as easy as it sounds, for exit doors tend to be well hidden in places that are dangerous to approach."
