What was aware that being was not there in sleep — and is there now?

Who is the one, it is aware, these are not beings, so what is the difference between the sleep, the heat and the waking sleep. You have to direct experience of sleep. Nobody has to tell you that I use sleep and you have the direct experience of waking up. So change between sleep and waking up, sleep there was no sense of being, waking there is a sense of being. So there must be an awareness which is aware that being was not there, now being is there. This awareness remains unknown through all of the states which might come into. Isn't it? So I do not have to tell you that you went to sleep last night, you know was aware. That means I am always aware. Yes. But you need sleep and there are no dreams.
