of parallel excitement is accompanied in the beholder by the sense
of unfamiliarity as in childhood, or by a neurotic hypersensitiveness, the
conditions are present for the production of intense _horror feminae_ or
_horror masculis_, as the case may be. It is possible that, as Otto Rank
argues in his interesting study, "Die Naktheit im Sage und Dichtung," this
horror of the sexual organs of the opposite sex, to some extent felt even
by normal people, is embodied in the Melusine type of legend.[194]

EROTIC DREAMS.--Our dreams follow, as a general rule, the impulses that
stir our waking psychic life. The normal man or woman in sexual vigor
dreams of loving a person of the opposite sex; the inverted man dreams of
loving a man, the inverted woman of loving a woman.[195] Dreams thus have
a certain value in diagnosis, more especially since there is less
unwillingness to confess to a perverted dream than to a perverted action.

Ulrichs first referred to the significance of the dreams of inverts. At a
later period Moll pointed out that they have some value in diagnosis when
we are not sure how far the inverted tendency is radical. Then Naecke
repeatedly emphasized the importance of dreams as constituting, he
believed, the most delicate test we possess in the diagnosis of
homosexuality;[196] this was an exaggerated view which failed to take into
account the various influences which may deflect dreams. Hirschfeld has
made the most extensive investigation on this point, and found that among
100 inverts 87 had exclusively homosexual dreams, while most of the rest
had no dreams at all.[197] Among my cases, only 4 definitely state that
there are no erotic dreams, while 31 acknowledge that the dreams are
concerned more or less with persons of the same sex. Of these, at least 16
assert or imply that their dreams are exclusively of the same sex. Two,
though apparently inverted congenitally, have had erotic dreams of women,
in one case more frequently than of men; these two exceptions have no
apparent explanation. Another appears to have sexual dreams of a nightmare
character in which women appear. In another case there were always at
first dreams of women, but this subject had sometimes had connection with
prostitutes, and is not absolutely indifferent to women, while another,
whose dreams remain heterosexual, had in early life some attraction to
girls. In the cases of distinct bisexuality there is no unanimity; 2 dream
