3626. Some persons are led by spirits to that degree, that they cannot return to what is true, but their phantasies have become so deeply rooted, that as often as they fall into those thoughts, they are so completely absorbed in them that they cannot be dispelled by change of circumstances, but they remain in the persuasion that things are as they imagine, and themselves also. When cases of this kind are obvious to the world, they are called open insanities, for from such insanity or phantasy they do not suffer themselves to be recovered, though apparently sane on all other subjects, as many insane persons are. It is a particular species of insanity, like that of a couple of men at Helm, one of whom carries about written papers, the other supposed himself to be a bird; though there are many of this character who are not generally regarded as such. All phantasies respecting spiritual things derive their origin from this source, and which prevail so far as they have induced persuasions.
