The only unnatural sexual behavior is none at all.

The unconscious - that is to say, the 'repressed' - offers no resistance whatever to the efforts of the treatment. Indeed, it itself has no other endeavour than to break through the pressure weighing down on it and force its way either to consciousness or to a discharge through some real action.

We are so made that we can derive intense enjoyment only from a contrast.

All 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.

The voice of the intellect is a soft one, but it does not rest until it has gained a hearing.

When it happens that a person has to give up a sexual object, there quite often ensues an alteration of his ego which can only be described as a setting up of the object inside the ego, as it occurs in melancholia; the exact nature of this substitution is as yet unknown to us.

Properly speaking, the unconscious is the real psychic; its inner nature is just as unknown to us as the reality of the external world, and it is just as imperfectly reported to us through the data of consciousness as is the external world through the indications of our sensory organs.
