Satire is making fun of things for being the way they are (in hopes that they'll change). I don't mind them seeing as they don't break the rules and over 90% of the users who make a blog like that never return after a week or so.
Rebellion is taking an active stand against something and usually implies that you cannot stand and want to change something through force (implying you just cannot live with it).
Fundamental difference: One side sees things as absurd, but generally doesn't mind them. The other sees things as completely inappropriate and needs to change now.
I always thought of sleeps to be similar to that of a computer's defragmenting process. As we go on about our business, our minds store information in random places in our minds and eventually it gets to the point where the information we pick up is so fragmented, it interferes with vital functions of the brain.
And sleep/dreams are simply our minds just sorting the information in an organized manor.
But in your concept, a wise man once said: "We go to bed every night defeated and die...only to be reborn the next day better, stronger, and wiser."
