I don't really know who you are, or what you are, or where you're from, or what you were doing when you found yourself between four, unfamiliar white walls.
Maybe you were waiting on your wife outside the ICU after she totaled your truck, or perhaps you were just about to one-two off the head of The Jabberwock, or you were yelling at that goddamn sponge to keep quiet while you finished your clarinet solo.
You might've just realized who the murderer was and had Watson's name on the tip of your tongue, only to shout it out to a framed painting from a scene in a book you'd read years ago, hung right in front of you. You might have turned to meet the barrel of a gun, but instead met the blankness of the museum staring back at you.
Space and time don't have to bend to your understanding. Don't be selfish. Don't be upset--these things happen after all--act with some poise!
And, please, enjoy our exhibits.

You guys wanna do a multiverse? You find yourself (your OC or a character from something) in a museum of everything that has ever happened in all of existence. Use your grammar and it'll be cool.
