According to Osho, dreams do not belong to the soul at all; they are the lifeblood of the mind. The mind dreams by projecting hopes and futures, while the soul abides in the present—content, choiceless, and without expectation. When realization unfolds, it comes as an undreamed surprise. Thus, equating dreams with the soul is poetic, not truthful.
Dreams come from your busy mind, not your quiet soul, which simply stays present.
