Now not to dismiss the possibilities of mass demon possessions of mind  … it really sounds like some sort of toxin … experimental or not …

Mysterious Tics in Teen Girls: What Is Mass Psychogenic Illness?

HERE Last fall, when a dozen teenage girls in a single upstate New York high school developed a condition that looked like Tourette’s syndrome — complete with sudden verbal outbursts, uncontrollable arm motions and facial tics — it seemed likely that a chemical toxin or infectious agent was to blame. But none could be found.

More recently, three other students at Le Roy Junior Senior High School, including one boy, developed the same baffling condition, prompting parents to call in the big guns: environmental activist and heroine of a Julia Roberts movie, Erin Brockovich, who has just stepped in to investigate possible environmental causes.

Brockovich’s team said it would be six weeks before tests of groundwater samples near the school could identify contamination, but in the meantime, doctors have already diagnosed most of the girls with a disorder: mass psychogenic illness — otherwise known as conversion disorder or, to use an outmoded term, mass hysteria.
