Here are some dream spells from the collection of magical Greek papyri: one in case you want someone else to have a dream, one in case you want to have a dream.

“If you wish to appear to someone in dreams during the night, say to the lamp that gets used every day, say to it often: Cheiamôpsei, Erpebôth: Let so-and-so, daughter of so-and-so, see me in her dreams, now, now, quickly, quickly. Then the usual, whatever you’d like.”

Ἐάν τινι ἐθέλῃς [ἐ]μφανῆναι διὰ νυκτὸς ἐν ὀνείροις, λέγε πρὸς τὸν λύχνον τὸν καθημερινόν, λέγε πολλάκις· ‘χειαμωψει: ερπεβωθ: ἰδέτω με ἡ δεῖνα, ἣν ἡ δεῖνα, ἐν τοῖς ὕπνοις, ἤδη ἤδη, ταχὺ ταχύ.’ καὶ κοινά, ὅσ’ ἂν βούλῃ.

PGM VII 405-411

“Request for a dream. Draw the god Hermes, upright and Ibis-faced, as accurately as possible on a scrap of linen cloth using quail’s blood, then, using myrrh, write his name above and say the words: Come to me, here, quickly, you who have the power. I call to you, the god of gods who is set over the spirits, to show me this in my dreams. By your father Osiris and Isis, your mother, I summon you to show me some image of you and reveal what I wish to know. By your name, Êiiouathi, Psrêpnousa Nertêr, Diokhasbara, Zarakhô, whom they call Balkham, reveal this, reveal everything that I ask.”

Ὀνείρου αἴτησις· Ἀκριβὴς εἰς πάντα γράψον εἰς βύσσινον ῥάκος αἵματι ὀρτυγίου θεὸν Ἑ[ρ]μῆν ὀρ[θ]όν, ἰβιοπρόσωπον, ἔπειτα ζμύρνῃ ἐπίγραψον καὶ τὸ ὄνομα καὶ ἐπίλεγε τὸν [λό]γον· ‘ἔρχου μοι ὡδὶ αἶψα, ὁ ἔχων τὴν ἐξουσίαν. ἐπικαλοῦμαί σε τὸν ἐπὶ τῶν [πν]ευμάτων τεταγμένον θεὸν θ(εῶν), δεῖξαί μοι καθ’ ὕπνους τόδε. ἐξορκίζω [σε]κατὰ [τ]οῦ πατρός σου Ὀσίριδος καὶ Ἴσιδος, τῆς μητρός σου, δεῖξαί μοί τι[να] μορφήν σου, καὶ περὶ ὧν θέλω, χρημάτισον. ὄνομά σοι· ‘ηιιουαθι, ψρηπνου̣α̣ νερτηρ, διοχασβαρα, Ζαραχω’, ὃν καλοῦσι Βαλχάμ· χρημάτισον περὶ τοῦδε, περ[ὶ π]άντων, <ὧν> πυνθάνω.’
