The author here tells us most plainly why he or she wants to fly like a bird--for the satisfaction of love. He says practically that merely by flying like the bird, he would have the embrace of the loved one. The opening lines of the chorus show that it is no far-fetched idea, that of seeing sex or love symbolism in birds flying or singing. We recall Burns's famous poem to the bonny bird that sings happily and reminds him of the time when his love was true. "Thou'll break my heart, thou bonny bird," he sings in despair. A false lover stole the rose and left the thorn with him. The entire poem is full of sex symbolism. That he too would like to have love, is what he says when he speaks of the bird singing. "The more one is occupied with the solution of dreams," says Freud, "the more willingly one must become to acknowledge that the majority of the dreams of adults treat of sexual material and give expression to erotic wishes.... No other impulse has had to undergo as much suppression from the time of childhood as the sex impulses in its numerous components; from no other impulse has survived so many and such intense unconscious wishes, which now act in the sleeping state in such a manner as to produce dreams." This, to my mind, can not be contested, and these wishes appear largely in the form of symbols. In early times sex was given great significance, and we know that in early myths and literature many events and things were sex symbols. When we dream symbolically, we go back to a method of picturing events that in early history had value, but of which the significance has been forgotten. The law of symbol formation is in dreams not an arbitrary one; it is based on forms of speech in the past and on witty conceptions of to-day. Folklore and wit are full of sexual symbols corresponding to those in dreams. All doubt has been removed of sexual symbolism in dreams by an experiment made by means of hypnotism, where a patient was told to dream some sexual situation. Instead of doing so directly she dreamed a situation in symbolic form corresponding to that in ordinary dream life. Rank and Sachs in their _The Significance of Psychoanalysis for the Mental Sciences_ have given us an excellent study of the nature of symbol formation. Freud has furnished us a list of objects and actions that are of sexual significance. W. Stekel has made an exhaustive study of the subject in his _Sprache des Traumes_ (1911). Freud recognises R. A. Scherner as the true discoverer of symbolism in dreams in his book _Das Leben des Traumes_ (1896), but he admits that Artemidorus in the second century A.D. also interpreted dreams symbolically.
