In solitary reverie we can tell ourselves everything. Our consciousness is still clear enough that we are sure that what we are saying to ourselves is really being said only to ourselves... The repose of sleep refreshes only the body. It rarely sets the soul at rest... Sleep opens within us an inn for phantoms. In the morning we must sweep out the shadows... Quite to the contrary, daytime reverie benefits from a lucid tranquility. Even it is is tinged with melancholy, that melancholy is restful, it is an engaging melancholy which gives a continuity to our repose... But the reverie would not last if it were not nourished by the images of the sweetness of living, by the illusions of happiness.
