Mandukya Karika, verse 4.35

Text

मित्राद्यैः सह संमन्त्र्य संबुद्धौ न प्रपद्यते ।
गृहीतं चापि यत्किंचित् प्रतिबुद्धो न पश्यति ॥ ३५ ॥

mitrādyaiḥ saha saṃmantrya saṃbuddhau na prapadyate |
gṛhītaṃ cāpi yatkiṃcit pratibuddho na paśyati || 35 ||

35. The dreamer on being awake, realises as illusory all the conversation he had had with friends, etc., during the dream state. Further, he does not possess, in the waking state, anything which he had acquired in dream.

Shankara Bhashya (commentary)

A man, in dream, holds conversation with his friends, etc. But, on being awake, he finds it all as unreal. Further, he possesses in dream gold, etc., but, in the awakened state he realises all these possessions to be unreal. Though he goes to other countries in dream, he does not, in reality, make any such journey.
