I believe in the existence of Ghosts, Vampires and Witches, although like you, Hauntmaster, not in the stereotypes.
We'll start of with Witches because that's an easy one - I'm a Pagan and have been for 9 years, my rituals and celebration of the sabbats deems me a witch and I am proud of the title because really, in that sense, it doesn't mean I have green skin and a big, warty nose. Although I do have a broomstick, or to use its magickal term, Besom, I can't fly on it

And I do have a cat, but he is ginger, not black
Now onto Vampires - I know for a fact that there are people who drink blood, haemovores is the technical term, I think.. And there are those who engage in bloodletting and bloodplay. They are technically vampires, but they aren't afraid of garlic and crucifixes and they don't go up in smoke when the sun comes up etc. There is also the theory of Psyvamps or Psychic Vampires - where people feed off of other people's energy. I do believe in this but I believe that often it is subconscious.. I think there's a little more to the drained feeling we suddenly get when we are surrounded by a lot of people in a public place or when we are round a certain individual.. who seems to always be energetic ..
My belief in Ghosts is somewhat more scientific. Although I have had first-hand experience of what I believe to be poltergeist activity (when I was 14) I am an advocate of the theory that ghosts are "recordings" on the atmosphere - the intangible presence of time that we can't see or hear of touch. If you see it in terms of electrical waves and impulses (which some theorists do), when a very traumatic event happens, the electrical energy spikes and causes a "scar" on the timeline/atmosphere. This continues to repeat itself infinitely - this explains why there are so many accounts of "Anniversary ghosts" (ghosts which always appear on the same night every year, such as the date of their death etc) and also explains why ghosts often appear unresponsive to our voice or touch. They are not really a physical entity - they are like a shadow of the person repeating an action that they have already done before. This theory also explains why some ghosts appear to be walking along with missing feet or a missing head - often when such cases are analysed, it is revealed that the building has had some structural alteration since the time period - that the ceiling has been lowered or the floor has been lifted, and they are walking on the original floor....
Spooky, eh?
