Chapter III: Sleep And Death
We see from this that when the senses create from their activity, immediately a creative faculty begins to stir in man. It is the same creative faculty which is at work in fully dreamless sleep, there giving rise to the state of soul we were describing as the antithesis of the waking state. For dreamless sleep, the astral body has to be withdrawn both from the etheric body and from the physical. In dreaming, while separated from the physical body—no longer joined to the physical sense-organs—it still remains connected to some extent with the etheric. The very fact that what is going on in the astral body is perceived in pictures, is due to its connection with the etheric body. The moment this connection too is severed, the pictures fade into complete unconsciousness; dreamless sleep ensues.
