You mean like those people who think they're Napoleon?
I've noticed that the theme of people who think they're Napoleon seems to pop up whenever mental illness is mentioned, both in this movie and in the original Dracula. Was this a common disorder back in the 1930's? Was Napoleon a popular historical personality in loony bins back in those days? Does the DSM IV cover this particular disorder?
In real life, anyone who masturbates comes back as a zombie.
