When the physical plane is taken from a person, then the dream remains as reality, because there is no contrast to prove it otherwise, and this state of existence is called Mirhal. He cannot experience on the earth now because he has lost the physical means. All the impressions that he has gathered upon earth are his world. It is the nature of the mind to gather as many impressions as it can. From this store the pictures that he sees are formed. We do not dream of what we do not know, of what we have not seen. The butcher sees the meat all day, and at night he does not dream of the dairy but of meat.
