When fantasies of others arouse other spirits, then it usually happens that he who is aroused by the other's fantasy hardly knows otherwise but that it is real, or that he is there, when yet it is not so. He is also allowed to realize this, sometimes very plainly, sometimes more vaguely, as even happened just now when others were aroused by those on high [3058]: then those being aroused hardly knew whether they were there or not, but they were given to realize that it was the fantasy of those [on high]. It has also quite frequently happened to me that due to the fantasy of others, I would be among them, so that even they could not tell otherwise. I then led them as spirits along paths, appearing in many places at the same time, and when I, having found out that it was a fantasy, afterwards told them that I was in bed, then I saw myself as it were with them. This fantasy, however, very often came back to me, for what reason I do not yet know. 1748, 5 Sept.

It is not permitted the learned to speak with spirits except with peril of life

I spoke with spirits and was given to see by a spiritual mental image that it is highly dangerous for any scholar who is steeped in fantasies to be able to speak with spirits, or for any revelation to be presented to him, this for a multitude of reasons.
