The word consciousness works either in the limited sense of the waking state, as opposed to sleep or trance say, or in the sense of the other's consciousness such as what a nurse would report. Words refer to things or matters of fact and these are the relevant respects of consciousness. But its full sense can only be to point to your own consciousness and in this way it breaks down, there is no thing or matter that is the place of all possible things or matters - it is like the universal set - so that the so-called unconscious (mind) would correspond to the Russell set, an empty concept. In this sense it is important to realise that consciousness does not exist - rather, if you could say so, consciousness is what you exist with, is the organ of existence. But again, there can be no such thing. If you must refer to it at least treat it as a gerund - consciousing = being. Awareness or intentionality is the way that consciousnessing symbolises itself by way of a subject-object escapement - behind their dance all of being is in play, without moving at all, naturally.
