I have changed my mind a-gain re the dissertation. I have decided to go with the idea of the 'Monster Within' - namely Dracula, Frankenstein, Jekyll & Hyde etc. Whatever - I will have to stick with this tradition, or my project will get very messy. I will possibly focus on ghosts/supernatural later, but I appreciate this is a vast topic. My dissertation lecturer is enthusiastic about it and has said it will be 'fizzy and interesting.'
