Fictional Like Truth
I've never done this before, but holy Mother of Gaia, this sounds like awesomeness wrapped in pure gold with a diamond-encrusted bow on top!

xd That's exactly what it feels like when you pass the 50k mark on time.

Fictional Like Truth
I've had this weird idea for a while (no true theme as of yet--merely concept): Vampires are spirits, not actual physical beings, that are like psychic parasites that possess and feed off the minds of human victims. Now, during the day (still using the archetype of sunlight as a vampires worst enemy), the vampire lies dormant within the host but still speaks to the host (as they do share the same body); however, at night, the host's body transforms into the vampire's original form. That's when the host lies dormant as a mere voice within the vampire's mind while the vampire frolics around the city doing as he pleases.
It sounds like a role playing game, though, and there's no significant theme behind the plot yet, so I may just write it for entertainment value rather than a lesson to be learned. (I'll get into my serious stuff later.)
A nice take on it, I like.
