Charles H. Spurgeon on Psalms 90:5

They are as a sleep. For as in the visions of sleep, we seeing, see not, hearing we hear not, tasting or touching we neither taste nor touch, speaking we speak not, walking we walk not; but when we seem to employ movements and gestures, in no respect do we employ them, since the mind vainly forms without any real objects images of things that exist not, as if they existed. In this very way, the imaginations of those who are awake closely resemble dreams; they come, they go, they confront us and flee from us; before they are seized, they fly away. —Philo, in Le Blanc.
