" If we dreamed the same thing every night, it would affect us as much as the objects we see every day. And if an artisan was sure of dreaming for twelve hours every night that he was king, I believe he would be almost as happy as a king who dreamed for twelve hours every night that he was an artisan.
...But because dreams are all different, and there is a variety even within each one, what we see in them affects us much less than what we see when we are awake, because of the continuity. This, however, is not so continuous and even that it does not change too, though less abruptly, except on rare occasions, as on a journey, when we say: 'It seems like a dream.' For life is a dream, but somewhat less changeable. "

― Blaise Pascal , Pensées
