In plain words
Just as a dream feels completely real until you wake up, so too your identification with the body, along with the apparent validity of perception and all other means of knowledge in the waking state, remains real only until you realize the true Self.
Close to the Sanskrit
Just as a dream is true up to awakening, so indeed and the state of being the Self as the body, and the validity of perception and other means of knowledge in waking, may be up to the realization of the Self.
