गोविन्द भाष्य (श्रील बलदेव विद्याभूषण - अचिन्त्यभेदाभेद वेदान्त ब्रह्मसूत्र भाष्य सटीक)

samṛddhiṁ tatra jānīyāt
tasmin svapna-nidarśane
"If, when the auspicious rites are completed, one sees a woman in a dream, he
should know that the rites were successful."
In the Kauṣītaki-brāhmaṇa it is said:
atha svapne puruṣaṁ kṛṣṇaṁ kṛṣṇa-dantaṁ paśyati sa enaṁ hanti
"If in a dream one sees a black man with black teeth, that man will kill him."
The word "tad-vidaḥ" here means "they who know how to interpret dreams".
These persons affirm that dreams reveal omens of good and evil. For example a
dream of riding on an elephant is a good omen, and a dream of riding on a donkey
is an omen of misfortune. In dreams one may also receive prayers. the Smṛti-śāstra
affirms:
ādiṣṭavān yathā svapne
rāma-rakṣām imāṁ haraḥ
tathā likhitavān prātaḥ
prabuddho buddha-kauśikaḥ
"Then Lord Śiva appeared in a dream and taught him the Rāma-rakṣā prayer.
Waking up in the morning, Buddha Kauśika at once wrote it down."
Therefore, because in dreams one sometimes receives omens, prayers,
medicines, and other things, and becauses sometimes a person will actually appear
in a dream, therefore sometimes dreams are as real as what is seen in the waking
state. That is the conclusion of Śruti-śāstra.
Here someone may object: Is it not true that after waking up a person becomes
convinced that what he saw in a dream was false. This proves that all dreams are
unreal.
In the following words the author of the sūtras answers this objection.
