During our life on earth we are conscious of three conditions: that of the body, the mind, and the soul. After physical death we are conscious of two only. On the physical plane, if a thief comes, we are not so much afraid. We look about to find something to attack him with. But in a dream we are afraid, for we have nothing with which to attack him. Here the will is much stronger; there the imagination is stronger, and the will less so. In the physical life we have changes from one experience to another. If in the night we are afraid, in the morning we say, "I had a nightmare," or, "in my dream I was sad," but it means nothing. But there we have no change.
