I think it was set in some far away future where civilization was lost. I remember there to be forests and stone wall cities like in the dark ages. The different thing was it was more a world for vampires. Although it wasn't just humans that were vampires, there were wolves, and other crazy critters. For some reason there was only yellow school bus that could be used as transportation. There was buses abandoned everywhere.

In the dream I was some kind of hunter of vampire animals. I didn't remember who I was, but had all kinds of flashbacks. I ran into a clan of people that travelled by boat along rivers hunting vampires that are human. In the dream I remember falling in love with the clan leader's sister. We then proceeded to a school that was haunted all around by young vampires. After being bitten myself we were surrounded.
