Doors and More Doors

You float to your left and scratch your eyes a bit. You finally see the full quantum realm for yourself over here and it's pretty awesome looking. You're coming apart at the seams, though, and you really are sick of this place. Luckily, the quantum realm is pretty much infinite, so you swim around a bit and eventually find a floating shack. On a grimy wooden slab above the door are the words "Johnny's Rezt Shakk" sprawled out in nearly illegible handwriting. You put your ear to the door. There's shuffling inside! The person in here must be Johnny, right? You had no idea there was even anybody in here, let alone a whole 'shakk', as it was spelled. You are heavily considering walking inside, but you don't want to be a nuisance. Your arms are quickly dissolving and you might not survive outside for long.
