Intentionality is consciousness by day, it's what you wake to. That there is non-intentional consciousness ought to be clear by the experience in every night, in sleep and perhaps not even only in sleep. You don't know it because you can't report on it, but giving a report should not be the necessary condition for consciousness.  Who says it is? To think so only begs the question. There are states in motion in which there is no distinction between subject and object. It's the most ordinary thing, more so that the waking self which is so arbitrary, so randomly assembled. To call it sleep is to treat it as if it were an exception, it is what lies beneath, extending without limit, and waking life only the turbulence and friction of its inner surfaces.
