There are practically no links between the goth and vampire scenes; they 
are two different subcultures with a very small amount of crossover.

When the mainstream media covers goth, it invariably involves vampire 
and witchcraft undertones for the /amusement/ of the general public.  
Interestingly, Peter Murphy (Bauhaus) has intimated that the seminal 
single "Bela Lugosi's Dead" -- named after the Count Dracula actor -- 
was released as a joke; unfortunately Bauhaus, and goth, has had to live 
with the punch line for a very long time.

Acts like Cradle of Filth (which the media tends to put in the "goth" 
camp, even though they are closer to black metal) use both vampire and 
gothic imagery; this only adds to the confusion.
