Reading the Consciousness it self is herculean task, forget about understanding it. Each and every persons consciousmess is just below the heads brain, which actually controls the glocose levels to the brain as well as sends the signals to all the body mechanisms through brains nerves. First of all understanding the brain itself is so difficult ferget about other conscious. as you may be well aware that Brain is not conscious, it is only sythesising the signals and sending them to and fro in to the body organisms through respective harmons and phermomes and ATPs * GTPs. To my knowledge most of the people even though they have this organ of conscious it doesnot function fully, because they have not developed it through consistent practice. If this conscious is there there would not be so many problems araising in this world called EARTH. The highly conscious organ is sensitive even for signals which tend to zero limits and zero timings. Unfortunately our quantums are so big in front of those zeros, but the quantums signals are so small for us. For passing and controlling signals this conscious organ doesnot require any power to battery it and also doesnot require any time lag also. But our physical brain requires so much energy and also some time to come to terms. But those who have developed this to some extent have very good humanly behaviour and pragmatic understanding towards other fellow humans. This is all because there is nothing precious than life itself, better use it for some practical way, so as others also get benefit and enjoy their life.

However your attempt for some explanations about conscious are good to read through quantum physics.
