"Freud maintains that a fantasy about two giraffes demonstrates Hans' mastering his castration complex. Hans says that a big giraffe came into his room during the night as well as a crumpled giraffe. Hans took the crumpled one away from the big giraffe and the big giraffe called out. After a while the big giraffe stopped calling out and Hans then sat on top of the crumpled giraffe. Freud interprets the giraffes as representing Hans' parents."
That's not right, or complete... the big giraffe represented the male genitals, the crumpled giraffe the female genitals and sitting on top of the crumpled giraffe represents his urge to have sex with his mother...
