6.46.2

vidmá te svapna janítraṃ devajāmīnā́ṃ putró 'si yamásya káraṇaḥ |
ántako 'si mr̥tyúr asi táṃ tvā svapna táthā sáṃ vidma sá naḥ svapna duṣvápnyāt pāhi ||2||

We know thy place of birth (janítra), O sleep; thou art son of the gods' sisters (-jāmí), agent of Yama; end-maker art thou; death art thou; so, O sleep, do we comprehend thee here; do thou, O sleep, protect us from evil-dreaming.
