Children also in the dream often signify the genitals, as men and women are in the habit of fondly referring to their genital organ as their “little one.” As a very recent symbol of the male genital may be mentioned the flying machine, utilization of which is justified by its relation to flying as well as occasionally by its form. To play with a little child or to beat a little one is often the dream's representation of onanism. A number of other symbols, in part not sufficiently verified are given by Stekel, who illustrates them with examples. Right and left, according to him, are to be conceived in the dream in an ethical sense. “The right way always signifies the road to righteousness, the left the one to crime. Thus the left may signify homosexuality, incest, and perversion, while the right signifies marriage, relations with a prostitute, &c.
