16.5.6

vidmá te svapna janítraṃ devajāmīnā́ṃ putró 'si yamásya káraṇaḥ |
ántako 'si mr̥tyúr asi |
táṃ tvā svapna táthā sáṃ vidma sá naḥ svapna duṣvápnyāt pāhi ||6||

⌊8.⌋ We know thy place of birth, O sleep; thou art son of the wives (-jāmí) of the gods, agent of Yama; ⌊9.⌋ ender art thou, death art thou; ⌊10.⌋ so, O sleep, do we comprehend thee here; do thou, O sleep, protect us from evil-dreaming.
