योगवासिष्ठः yogavāsiṣṭhaḥ - book-7, chapter-167, verse-22

यथा संवेद्यते यद्यत्तथा तदनुभूयते ।
सद्वासद्वा भवत्स्वप्ने व्योम्नीव सदसच्च तत् ॥ २२ ॥

sadvāsadvā bhavatsvapne vyomnīva sadasacca tat 22

22. As a thing is known to be in its imagination, so it is impressed also in our conception of the same; and as anything appears either as real or unreal in the dream, we retain the like idea of it in our waking also.
