To say that consciousness is all there is is to say that only the experiencing is. This means that the objective is pre phenomenon and does not exist i any separate way in its own right. The point is to not put belief on to another kind of reality that lies on the other side of the experiencing, even if that other kind of reality is theorised as 'frozen' consciousness, or dissociated consciousness experienced 'from the outside'. This kind of belief is the idealist version of physicalism. 'Consciousness only' is a far more radical belief. What the two have in common, however is that they each force a revision of what consciousness is understood to be, but the correct revision removes all putative objectivity or objecthood from consciousness and from its apparent objects.
