From dreams, in sleep or swoon, of a character difficult to believe in we pass by way of “hallucinations” to ghosts. Everybody is ready to admit that dreams do really occur, because almost everybody has dreamed. But everybody is not so ready to admit that sane and sensible men and women can have hallucinations, just because everybody has not been hallucinated.
