We all read the stories when we were little, didn’t we? A bunch of children go into a wardrobe, or through a tiny door that’s only bricked over sometimes, or find a secret key, go down a rabbit hole, cross a bridge, fall into a book, vanish. Then there’s magic, and adventure, and villains for the children to test themselves against. At the end they come back and no time has passed, no one realized they were gone.
It’s bullshit.
