Pathology has made us acquainted with a great number of states in which the boundary lines between the ego and the external world become uncertain or in which they are actually drawn incorrectly. There are cases in which parts of a person's own body, even portions of his own mental life - his perceptions, thoughts and feelings -, appear alien to him and as not belonging to his ego; there are other cases in which he ascribes to the external world things that clearly originate in his own ego and that ought to be acknowledged by it.
Sigmund FreudIt is no wonder if, under the pressure of these possibilities of suffering, men are accustomed to moderate their claims to happiness - just as the pleasure principle itself, indeed, under the influence of the external world, changed into the more modest reality principle -, if a man thinks himself happy merely to have escaped unhappiness or to have survived his suffering, and if in general the task of avoiding suffering pushes that of obtaining pleasure into the background.
Sigmund FreudWhen the wayfarer whistles in the dark, he may be disavowing his timidity, but he does not see any the more clearly for doing so.
Sigmund FreudAll elongated objects, such as sticks, tree-trunks and umbrellas(the opening of these last being comparable to an erection) may stand for the male organ...Boxes, cases, chests, cupboards, and ovens represent the uterus...Rooms in dreams are usually women...Many landscapes in dreams, especially any containing breidges or wooded hills, may clearly be recognized as descriptions of the genitals.
