svapna-āveśe - when absorbed in dreams; preme - in love of Kṛṣṇa; prabhura - of Śrī Caitanya Mahāprabhu; gara gara - fully absorbed; mana - mind; bāhya haile - when He awakens; haya - it is; yena - as if; hārāila - He has lost; dhana - something very precious.

When Śrī Caitanya Mahāprabhu dreamed of the rāsa dance, He was fully absorbed in transcendental bliss, but when His dream broke, He thought He had lost a precious jewel.
