@kennethamy,
As long as I have not awakened from being awake, I see no reason to think that awake is a dream. Even the past, which may seem a dream, leaves the scars to indicate a connection to the present state of awake.
I know I am awake, as well as anything can be known, however, in dreams I sometimes believe I am awake.
