You could say so, yes, but for most people it would be utterly misleading.

In the separated state, there’s a clear distinction between conscious and unconscious. There’s a lot of activity in the unconscious. In the enlightened state the distinction between conscious and unconscious ceases to be.

So you could say that everything becomes conscious, or that everything becomes unconscious. These statements are equivalent, and equally absurd since there is no distinction anymore.

However, if by “unconscious” you don’t mean the unconscious/subconscious mind, but unconscious as in “he was knocked unconscious”, that is, total loss of all sensory input and awareness of one’s surrounding, than it’s completely the opposite. The contents of subconscious mind are actually what prevents us from fully experiencing our senses and being fully aware of our environment. But of course, we don’t know, because it all happens below the current reach of our consciousness.
