19.57.3

dévānāṃ patnīnāṃ garbha yámasya kara yó bhadráḥ svapna |
sá máma yáḥ pāpás tád dviṣaté prá hiṇmaḥ |
mā́ tr̥ṣṭā́nām asi kr̥ṣṇaśakunér múkham ||3||

Embryo of the wives of the gods, instrument of Yama, excellent dream; the evil [dream] that is mine, that do we send forth to him that hates us.

Thee that art "harsh" by name, mouth of the black bird (-çakúni)—thee, O sleep, we thus know completely; do thou, O sleep, as a horse a halter, as a horse a girth, scatter him who is not of us, the god-reviler, the mocker.
