Recently while pondering strange objects of esoterica, I came across a historical article regarding Elizabeth Bathory, the Hungarian “Blood Countess”, whose grisly crimes against virgin peasant girls (the blood of which she believed could be used to preserve her own youth) secured her the title of the most prolific female serial-killer in history. Whether it be due to the fact that Bathory abducted her victims by the cover of night, or perhaps for some other less-obvious reason, somehow I began brainstorming what kinds of parallels might exist between modern Ufology and Vampires (obviously referencing the fact that at least most UFO abductions are reported at night, and often in people’s homes, much like vampires entering a maiden’s window under the cover of darkness). Initially, I only managed to muster the following points of parallel:
1) Vampires, much like aliens, are indeed known for abducting their victims
2) Vampires and aliens both tend to prefer operations during the cover of darkness
3) Alien-like creatures often associated with UFO sightings (like the Mothman of Point Pleasant, West Virginia) often bear similarities to vampires
4) Chupacabras exhibit rather vampiric traits, and are often associated with UFOs
Along these lines, I was reminded of a bizarre “vampire” creature recently reported by Scott Corrales, over at his website Inexplicata, which is normally devoted to the study of Latin American Ufology. However, Corrales shares at his blog recent encounters with a creature described as a “Man Bat” seen in the vicinity of Cimbraplay, near Saenz Guerrero, Chihuahua, said to have been linked to the deaths of

I love the idea and the article.
I was actually in a discussion about Demons being Greys over on a forum I frequent, so your entry here really caught my eye.
But the vampire / UFO link made me think of Ed Wood’s “Plan 9 From Outer Space”.
Maybe Ed was on to something…LOL
Anyway, Like I said, great article…please keep going!
