Have not had time to watch vid yet, and I don't know if I understand you correctly, but in advaita there is only one reality and the objects of the senses are not self-existent but forms or shapes consciousness takes on ie basically ideas arising within consciousness and therefore not separate from it. The forms consciousness takes on appear to be intrinsically separate from it because the act of perception itself splits the one reality (consciousness) into observer (ego, or separate self) and observed, but both are interdependent aspects of consciousness which in reality is both subject and object.
In its contentless primal state, reached in deep concentration, sensory perception with its illusory subject-object distinction is transcended and consciousness is 'empty' of form. In its formless state there is no awareness of separate beings, just pure be-ing, which is consciousness in itself, rather than consciousness of something 'other' than it, as in perception. What appears in perception to be separate beings from it is nothing other than its own activity....the act of perception itself. There is no 'real' substance or form, only infinite awareness and the ideas arising within it.
