I don't really care one way or the other. I've met some quite nice, well-bred vampires. Stereotypes are so harsh. You guys don't even run around in capes like the movies told me you would, so I generally ignore what other people say.
I'm more of a telepath than a witchcraft psychic, and from the little I know about the difference between the two, it might be a little more applicable to what you're talking about.
I mean...I'm thinking about this now. Theoretically speaking, the best way to figure out whether or not it was just a fluke would probably either be to go in and poke about, or for you to go to sleep and then wait until you dreamed. But who knows if you will again, so that one's a bit iffy. Unless this is becoming a regular occurrence?
