Long story short, I dreamed i was on a train when vampires attacked etc. and i had to experience the (painful) transformation from regular human to vampire.

After i'd turned I felt this powerful lust for blood, (and beer lol) and had to feed with all the other vampires, hunting down other people to live.

It was an awesome dream and I went lucid halfway through and just sort of continued on with the theme and the story.

Last little detail, when i was a vampire I had enhanced athletic ability and could run muc faster and jump heaps higher.
