Man, I'm trying to read "The White Goddess" by Robert Graves. It's a pretty tough read but an excellent book. I found this passage that was so wonderful that I had to share...
"The night mare is one of the cruellest aspects of the White Goddess. Her nests, when one comes across then in dreams, lodged in rock-clefts or the braches of enormous hollow yew, are built of carefully chosen twigs, lined with white horse-hair and the plumage of prophetic birds and littered with the jaw-bones and entrails of poets. The phropet Job said of her:'She dwelleth and abideth upon the rock. Her young ones also suck up blood.'"
Sure sounds like an opium dream to me!
Love!!
