I felt an absolutely indescribable sense of menace. It was hell on earth to be there [in the presence of the entities], and yet I couldn't move, couldn't cry out, couldn't get away. I'd lay as still as death, suffering inner agonies. Whatever was there seemed so monstrously ugly, so filthy and dark and sinister. Of course they were demons. They had to be. And they were here and I couldn't get away.
