Mandukya Karika, verse 4.64

Sanskrit text, IAST transliteration and English translation

स्वप्नदृक्चित्तदृश्यास्ते न विद्यन्ते ततः पृथक् ।
तथा तद्दृश्यमेवेदं स्वप्नदृक्चित्तमिष्यते ॥ ६४ ॥

svapnadṛkcittadṛśyāste na vidyante tataḥ pṛthak |
tathā taddṛśyamevedaṃ svapnadṛkcittamiṣyate || 64 ||

64. These (beings) which are objects of the mind of the dreamer have no existence apart from his mind. Similarly, this mind of the dreamer is admitted to be the object of perception of the dreamer only. (Therefore the mind of the dreamer is not separate from the dreamer himself)

Shankara Bhashya (commentary)

Those¹ beings perceived by the mind of the dreamer have no existence outside the mind of the person who dreams about them. It² is the mind alone which imagines itself to have assumed the forms of many diversified beings. Similarly,³ that mind of the dreamer is, again, perceived by the dreamer alone. Therefore there is no separate thing called mind which is apart from the dreamer himself.

Anandagiri Tika (glossary)

¹ Those, etc.—The truth about this statement is clearly understood in the waking state.

² It is, etc.—In the dream, the mind alone objectifies itself into the perceiver and the perceived.

³ Similarly, etc.—The mind of a man is not cognized by any other being excepting himself. The cognizing ego is also created; by the mind. The ego and the non-ego come into existence together. Therefore, the charge of solipsism cannot be levelled against the Vedāntist.
