Śrīmad-Bhāgavatam · Text 11.22.41
Who is speaking and story frame
स्वप्नं मनोरथं चेत्थं प्राक्तनं न स्मरत्यसौ ।
तत्र पूर्वमिवात्मानमपूर्वम् चानुपश्यति ॥ ४१ ॥
svapnaṁ manorathaṁ cetthaṁ
prāktanaṁ na smaraty asau
tatra pūrvam ivātmānam
apūrvam cānupaśyati
Just as a person experiencing a dream or daydream does not remember his previous dreams or daydreams, a person situated in his present body, although having existed prior to it, thinks that he has only recently come into being.
