In another important reminiscent passage, he wonders that he had not realized before what was happening to him, because for many years, he says, such remarkable proofs existed. "Not only were there dreams for some years, informing me concerning the things that were being written, but there were also changes of states while I was writing: a certain extraordinary light in the things that were being written . . ." 12
There is no doubt that for a scientifically minded man, as he looked on himself, he was in an embarrassing situation with these "occult" experiences and in a state of painful bewilderment in regard to his sanity. In his work on The Fibre, written in 1741-42, he said some things about mental diseases in which may be seen veiled references to the suspicions that most likely beset him.

As proof he cited the case of persons "skilled in the art of magic" from the northern regions. (The Lapps in the north of Scandinavia have always had a reputation for shamanistic mediumism.)
Such persons, Swedenborg said, "are credited with being able to
