“Sleep occupies a third of our life. It is the consolation to the woes of our days or the woe of their pleasures; but I have never found that sleep was a rest. After a swoon of a few minutes a new life begins, freed from conditions of time and space, and doubtless like the life which awaits us after death. Who knows whether there does not exist a link between these two existences, and whether it is not possible for the soul now to bind them together?”

—  Gerard de Nerval, Aurélia
