The Dark Magic of Sleep Paralysis in Silvermore Creek

"If one were to ask a student who attended camp Silvermore Creek during the year of 1979-- in the middle of an unnamed California forest-- what they remembered, they would not be able to help but answer with a look of reminiscing horror. The events taking place were truly traumatic for every child. All of those who went home unable to rest comfortably in their rooms, keeping a flashlight on each of their nightstands, crucifixes resting over their beds, and overdosing themselves with caffeine in order to keep the demon away. When ignorant parents, horrified for their children, sent some of them to mental asylums or attempted to soothe fears of what they assumed were of the boogeyman, the children only shook their heads and repeated under their small breaths, 'vigilate peccatis vestris: nolite loqui verbum tuum in consanguineis ac prope oculis vestris, reddere pretium' "
