> I'm probably not the first person to think about this, but if you stand in front of a mirror in a well-lit room and close your eyes, do you still have a reflection?

Uhm. Following the reasoning exposed by Dietrich Korthenhaus in a lecture at the German Wasserschule of Rostock and later developed at the cultural club of the famous Epikureuter Cafe' in Hannover...

"Vampires, and only vampires as far as I know, don't have a reflection.
So, if you don't have a reflection you are a vampire.
Everytime you close your eyes you stop seeing your reflection, so -from your point of view- you don't have a reflection anymore; this demonstrates that if you close your eyes you become a vampire; wheter or not you are dangerous for other people or only to yourself depends on the fact that other people may or may not see your reflection." (from D.Korthenhaus, "Epikureuter papers", Berlin, 1974)

Luciano Mollea, an Italian philosopher and landlord that lived in Turin, extended these concepts in a book of which we got only the first two chapters, written before he disappeared after a contact with an hijacked UFO that landed in emergency near his farm in Cuneo.
