When the protagonist enters Eternity it's clearly established that no time passes when you're inside. You will leave the exact same time you entered. And MacCruiskeen says he's been there quite a while that morning using his lack of beard as proof. But that's impossible! If you leave the exact same time you enter them you will never meet another person inside. At least, not someone who didn't enter at the same time as you. MacCruiskeen would have entered and since no time passes while he's in there no one else would ever be able to enter after him until he leaves. And don't give me that "it was all a dream" excuse because that can get around any leap in logic. We might as well say it was all fictional.
