For all crackyfag who like films: I recommend you the psychoanalysis film '' The Pervert's Guide to Cinema '' An analysis of different movies about what happens when the ghostly component from which are made as thelibido and the dreams, is fulfilled. When this ghost is captured, the fantasy dies, becoming a nightmare. Forcing us to escape back to reality.

The man has the need to idealize the woman and therefore he kills her, because he denies her individuality.
The femme fatal is the woman who cannot be idealized, shes is also a nightmare.

What its behind of all this is the need of the man to posses the woman, to kill her in order to proyect his fantasies on her. The idealization as way to scape from reality.
But are the dreams for the weak who can't endure reality? Or is reality, for those who can't cope with dreams?
