That human souls imagine they are people on earth, equipped with bodies, you may see spoken of earlier [207, 296, etc.], even thinking they have clothes on, so that only with difficulty can they be torn away from their fantasy. They also speak together among themselves, just as they had in this world; for speaking is only the putting together of a series of mental images, which, with people in the body, falls into the words of their native language. It is the mere putting together of mental images of spirits that fall into words with a person on earth, and for this reason, all of them speak in the person's language, even among themselves, of which the person may or may not be aware - or even speak in a strange language, as is well known: for the apostles were able to speak in any language [Acts 2:4], and this came from spirits. Moreover, there is also a communication of mental images, as there is of words. In fact, by these alone, joined together, they can express more things within a minute than man can express by words in entire hours. I have learned this from a great deal of experience, in the course of which it became evident that souls speak among themselves, and indeed, just like people in this world; and I have even heard that they can also preach in the same way, the one teaching the other.
