From the daily Steiner website:
In all the experiences I have been describing, man’s consciousness is far clearer and more awake than the ordinary consciousness of his life on Earth. It is most important to distinguish the various degrees of human consciousness. Consciousness during dream-life is dull, consciousness during waking life is clear, consciousness after death still clearer. As a dream is to reality, so is all our life on Earth in comparison with the clarity of our consciousness in the life after death. Moreover, at each new stage in the life after death, consciousness becomes still clearer, still more alert.
