My general rule is that if Reg Shoe lets ’em in, they’re undead.
Vampires are undead.
Stern (YU) has a science and Judaism journal every year and people tend to write about very… interesting stuff- a girl once wrote about porphyria and how it might have related to Esav (IIRC) and, of course, used the vampire tagline. It was actually a very interesting essay. Those journals are fun to read.
