Michael is again talking about his dreams. Here, he comments on a passage from On prophesying by dreams. Aristotle says in this passage that dreams are more vivid when they involve things we are anxious or thinking about. Michael disagrees--dreams about our anxieties (or even our recent conscious thoughts) are not the only ones that can be extremely vivid. We can have dreams about things that are not on our minds, as well, that feel just as bright and real. As an example, he mentions a dream he had about a colleague who died when he was young, and whom he (curiously) distinguishes from his current, more famous, colleague and collaborator on ‘the discourses’. The names of both have been lost to time.

"And in fact [we have vivid dreams] even if something else should appear to us, [something] which we are not [currently] thinking about. Like the time I saw my colleague in a dream—not my famous [colleague], who is alive and working with me on the discourses (τοὺς λόγους), but another one who, because of the quick approach of death, wrote down only a few works in philosophy—anyway, I saw the one who died long ago in a dream; he was discussing things with me which I had not thought about during that whole month, or even the month before, [but which I] had thought about a lot in earlier times. For both my questions to him and his answers to me were about the soul."

καὶ γὰρ κἂν ἄλλο τι ἡμῖν φαίνηται, οὗπερ οὐ φροντίζομεν· ὥσπερ ἐμοὶ ἰδόντι τὸν ἐμὸν ἑταῖρον, οὐχὶ τὸν κλεινόν μοι τουτονί, ὅστις ἔτι μοι ζῶν συμπονεῖ περὶ τοὺς λόγους, ἀλλ' ἄλλον ὀλίγους ἐν φιλοσοφίᾳ πόνους καταβεβληκότα διὰ τὴν τοῦ θανάτου σύντομον προσέλευσιν, ἐγὼ γοῦν ἐκεῖνον πάλαι θανόντα εἶδον καθ' ὕπνον διαλεγόμενόν μοι, περὶ ὧν ἐγὼ κατ' ἐκεῖνον ὅλον τὸν μῆνα καὶ ἔτι τὸν πρὸ ἐκείνου οὐκ ἐφρόντισα, πρότερον πολλὰ φροντίσας· ἦσαν γὰρ περὶ ψυχῆς αἱ ἐμαί τε πρὸς ἐκεῖνον ἐρωτήσεις κἀκείνου πρός με αἱ ἀποκρίσεις.
