A short door riddle

You try each item anyway, and eventually find out that the book has something in it, it has a phrase, " One who clips out of reality can only stay out of reality" You and Eclipse are unsure of what that means, but then Eclipse has a thought,
" What if when we fell, we fell out of the world? Sort of like when you break out of a games boundaries we broke out of this world's boundaries?"
You agree that, that might be the case, but what do you do now?
