Yadubara: Śrīla Prabhupāda. At the time of sleeping, there is a subtle reality that the subtle body enters into?
Prabhupāda: Yes. Reality means as you take this awakening vision as reality, similarly, the dream vision is also real.... Nothing, none of them are reality. They are all temporary.
Yadubara: But that subtle reality is just as real as this gross reality?
Prabhupāda: Yes. They'll not stay. This reality will not stay.
Hari-śauri: It's all a dreamlike existence.
Prabhupāda: Yes, simply a long duration dream. Do you think this skyscraper building will stay? Nothing will stay. It may stay for five hundred years or five thousand years. But is it not permanent. Anything you take—the trees, this land, nothing; even this ocean. Bhūtvā bhūtvā pralīyate (BG 8.19). It appears again and again disappears, that's all. Everything. The material world means that. Bhūtvā bhūtvā pralīyate. Vyaktāvyaktam. Sometimes manifested, sometimes not manifested. This town is manifested, and one big wave of sea, it will be nonmanifested, immediately.
