Sleep isn't real.
Y'all be taking MLP pretty fucking seriously. Like damn, of course they'll do questionable shit in the show but it ain't something worth over thinking for fucks sake. I mean the world is fictional, it runs on a different level than we do. In some alternate timeline, maybe the show is a bit realistic— but we aren't in that timeline now are we? The show is very saccharine, and it's gonna play it up a lot.
