"The Confused Dream... by far the commonest of all, may be caused... in various ways. It may be simply a more or less perfect recollection of a series of the disconnected pictures and impossible transformations produced by the senseless automatic action of the lower physical brain; it may be a reproduction of the stream of casual thought which has been pouring through the etheric part of the brain; if sensual images of any kind enter into it, it is due to the ever-restless tide of earthly desire, probably stimulated by some unholy influence of the astral world; it may be due to an imperfect attempt at dramatization on the part of an undeveloped ego; or it may be (and most often is) due to an inextricable mingling of several or all of these influences. Ch 5"
