dream a dream as a means of communication In a number of languages there are different terms for ‘dream’ depending upon the nature of the dream. A frightening dream without special significance or a dream with erotic implications may be referred to by terms which are quite different from a term referring to a dream which carries important meaning, in other words, a dream which constitutes a type of vision or symbol of some reality.
1 The meaning of ὄναρ and ἐνύπνιον could be classified as a psychological state, but their direct connection with communication seems to justify their being included in this domain.

Moulton & Milligan — Vocabulary of the Greek NT
ἐνύπνιον. This common LXX word (cf. Ac 217) may be illustrated by two passages from the Paris Papyri, both belonging to ii/s.c., P Par 44° (B.c. 153) (= Witkowski, p. 82) ἐγὼ yap ἐνύπνια ὁρῶ πονηρά, 47°° (c. B.C. 153) (= Selectéons, p. 23) ἀποπεπτώκαμεν πλανόμενοι ὑπὸ τῶν θεῶν καὶ πιστεύοντες τὰ ἐνύπνια, ‘‘ we have fallen from hope, being deceived by the gods and trusting in dreams”: cf. the heading of P Leid C (B.c. 163-2) τὸ ἐνύπ[ν]ειον ὃ [et]5ev Tayns. From the inscrr. we may cite Sy// 802% (iii/B.c.) where the lame and the blind became whole—évirrvioy ἰδόντας μόϊνον (ἐνύπνιον = ὄψις), and Preisigke 685 (ii/B.c.) ἐνύπνια κρίνω, Tod θεοῦ πρόσταγμα ἔχων, TUX’ ἀγαθᾶι.
