Joreggelt.

He's waking up slowly, to the soft humming of the ventilation fans. He's lying on a bed, in a dimly lit room. The blinds are half down, but the lights of an apparently sunny afternoon creep into the room. He gets up and goes to the window, but the sun is dazzling he can't really discern anything outside. He's more interested in the immediate environment anyway. Turning back, he takes a look at the room. He's never been here before. Looks like a private hospital room, a very comfortable one. There's even a writing desk standing in the corner, next to the window, with a computer on it...made out completely of LEGO pieces! Nevertheless, it must be a real one, it's on and humming. Next to it, in the corner, is a framework, could be anything, but it's obviously a difference engine to solve 3rd order polynomials. Also made of lego parts. The other part of the room is mainly occupied by the hospital bed he was sleeping on, and some medical machines to the sides. One of these shows his cardiogram - in small green lego bricks on a black background.
"That's funny", he thinks.
Looks like someone turned half his room into lego bricks. Closest to his bed, there's a small plastic bag of blood or some other solution, hanging from a stand. He just realizes that all the time a long tube extending the plastic bag was connected to his vein.
"What the...?"
Hmm, what might have happened to him after all and what is he receiving from that bag? He takes a step closer, winks his eye and takes a very sharp look... the plastic bag seems to be filled with tiny red...lego bricks. He can see the pieces flowing neatly in the tube right into... Then he notices his hand. His palm, his fingers, all nice, flawless yellow lego bricks.
"Aaaaaaaaaaaaaaaaaaaaaaaaa!", he screams, before deciding to faint instead.
