Unless only a single subject exists - that which "we" call the universe.
If, as some believe, only a single "witness" or "entity" exists (some call it simply the "Self"), then there is no real "object" that's separate; thus no "objective world". If all is the Self (in Hinduism, this Self is referred to as Brahman), then everything, and non-thing, is subjective in existence and non-existence (manifest and unmanifest, or conscious and unconscious).
So, you could say that there are two "levels" of truth (in the case that all is Brahman), one relative to our individual perspectives as persons within an objective world and another, "higher truth" (or Truth), within which all is the single Subject (I suppose you could say that the universe is its body and the combined perception and intellect of all conscious beings, its mind).
