386. If we dreamt the same thing every night, it would affect us as much as the objects we see every day. And if an artisan were sure to dream every night for twelve hours' duration that he was a king, I believe he would be almost as happy as a king, who should dream every night for twelve hours on end that he was an artisan.
If we were to dream every night that we were pursued by enemies and harassed by these painful phantoms, or that we passed every day in different occupations, as in making a voyage, we should suffer almost as much as if it were real, and should fear to sleep, as we fear to wake when we dread in fact to enter on such mishaps. And, indeed, it would cause pretty nearly the same discomforts as the reality.
But since dreams are all different, and each single one is diversified, what is seen in them affects us much less than what we see when awake, because of its continuity, which is not, however, so continuous and level as not to change too; but it changes less abruptly, except rarely, as when we travel, and then we say, "It seems to me I am dreaming." For life is a dream a little less inconstant.
