Psychologically: In dreams above all with young people, superman appears regularly. One does not understand the world yet surely and feels put under permanently. There one already dreams of the superforces with which one is able to do all problems simply hinwegfegen. If adults still have such dreams, points mostly to a serious mental disturbance. A deep feeling of the inadequacy should be compensated by megalomania. If such dreams pile up, one should turn to a psychologist.
