With EMS, the symptoms are real whether or not those people can actually detect wifi hotspots. Similarly, it seems like the vampires genuinely have symptoms which are cleared up by drinking blood. Now, if someone believes "wifi hotspots give me headaches", that's untrue. They only get headaches when they believe there's a hotspot nearby. This has been demonstrated in general, and it should be easy to demonstrate to any individual sufferer. After that demonstration, if someone continues to believe that wifi hotspots give them headaches, then it may be reasonable to call them delusional. But that doesn't make their symptoms go away. What specific belief do you think vampires have, that you think has been demonstrated untrue?
