योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-186, verse-26

विभागहीनयाप्येष भागश्चिद्धननिद्रया ।
सुषुप्तान्मुष्यते मोक्ष इति स्वप्नस्तु चित्तकम् ॥ २६ ॥

vibhāgahīnayāpyeṣa bhāgaściddhananidrayā ,
suṣuptānmuṣyate mokṣa iti svapnastu cittakam 26

26. vibhāga-hīnayā api eṣaḥ bhāgaḥ cit-ghana-nidrayā
suṣuptāt muṣyate mokṣaḥ iti svapnaḥ tu cittakam

26. eṣaḥ vibhāga-hīnayā api bhāgaḥ cit-ghana-nidrayā (āvṛtaḥ
bhavati) mokṣaḥ suṣuptāt muṣyate iti svapnaḥ tu cittakam

26. Even this undivided part (of consciousness) is veiled by the dense sleep of consciousness. The idea that final liberation (mokṣa) is 'stolen' from deep sleep—meaning that deep sleep itself is liberation, which is then lost—is merely a dream of the mind (cittakam).
