Dreams.

And Alex dreams that he is sitting on a pair, and he is sitting on a pair. And he sleeps.

By the way, yes, in the dream I didn't just sit, but actually woke up. Quite funny, because the fact that you wake up here usually shows that it's real. What if I didn't wake up from this dream either, would I have a full life in a dream? Or maybe I really woke up inside a dream and am sleeping...
