VII. Inner Processes in the Human Organism. Sense-Perception, Breathing, Sleeping, Waking, Memory

What is it that actually goes on in sleep? Here I must remind you of something I said here very recently, describing how during sleep, with his astral body and his ego, man always lives through in backward order what he has experienced in the physical world in the preceding waking period. Let us take a regular waking period and a regular sleeping period—it is however just the same for irregular periods. A man wakes up on a certain morning, busies himself during the day, goes to rest in the evening and sleeps through the night for about a third of the time he has been awake. Between waking and going to sleep he has a series of experiences, daytime experiences. During sleep he actually lives through in backward order what had been experienced during the day. The life of sleep goes backward with greater rapidity, so that only a third of the time is needed.
