In the telling it has the contours of a creation myth: At a time of great evil and great terror, a small group of scientists, among the world’s greatest minds, secluded themselves in the desert. In secrecy and silence they toiled at their Promethean task. They sought the ultimate weapon, one of such great power as to end not just their war, but all war. They hoped their work would salvage the future. They feared it could end everything. -

"Scrape marks inside the broken ends of limb bones indicate that marrow was removed." "Whatever actually happened at Herxheim, facial bones were smashed beyond recognition." -

"Common images are bearded, goblin-like demons laughing or whispering sinister speech, a faceless girl (usually covering her face with hair, moving around in bed moaning and feeling my body), hands appearing from the wall and attempting to strangle me. A hung man talking in the corner of the room, and some of the most bizarre experiences may include up to a dozen 'critter' entities (think Gremlins movie) laughing and talking about me. The environment tends to feel like a holographic dollhouse, the experience peaks and then the hallucinations mysteriously vanish when I regain control of my body."- The bizarre world of
sleep paralysis, a form of
hypnagogia and root of many folkloric figures such as succubi or incubi and the
night hag.

16% of US science teachers believe human beings have been created by God within the last 10,000 years. 25% of science teachers spend some time teaching about creationism or intelligent design. 12.5% teach it as a "valid, scientific alternative to Darwinian explanations for the origin of species". 2% say they do not cover evolution at all. Teachers who have taken more science courses themselves devote more time to evolution - "This may be because better-prepared teachers are more confident in dealing with students' questions about a sensitive subject."
