Interesting. While I don't discount much of anything, I do not give much credence to this. But hey, my kid has done stranger things.
I think something in the food, like in the Salem Witch Trials, maybe? The scientists think that the "witchcraft" hysteria was started mostly because ergot poisoning. Not sure that is exactly the right name for it, but a fungus in the rye they ate caused the symptoms that were supposed to be witchcraft AND the hysteria by many of the people. Tho, in Salem, I am sure it was also used by the people in charge to push an agenda.
Anyway, some type of poisoning or other is my bet. Or a drug problem.
