BṚHADĀRAṆYAKA UPANISHAD · 4.3.34

स वा एष एतस्मिन् स्वप्नान्ते रत्वा चरित्वा दृष्ट्वैव पुण्यं च पापं च पुनः प्रतिन्यायं प्रतियोन्य् आद्रवति बुद्धान्तायैव ॥

sa vā eṣa etasmin svapnānte ratvā caritvā dṛṣṭvaiva puṇyaṃ ca pāpaṃ ca punaḥ pratinyāyaṃ pratiyony ādravati buddhāntāyaiva ॥

And Yâgñavalkya said: 'That (person), having enjoyed himself in that state of sleeping (dream), having moved about and seen both good and bad, hastens back again as he came, to the place from which he started, to the state of waking.
