I don't know about others, but for me, I have been recording between 3 to 6 dreams a morning most days, but still with most of my dreams I definitely don't know I'm dreaming until I wake up. I may see or do very odd things, but not realize how nonsensical it is until the dream is over. Occasionally, I'll have lucid dreams, though, and in a lot of those I somehow already "know" it's a dream from the very beginning without seeing something odd happening first.

There have been occasions where I've had vague realizations that something doesn't seem right or been surprised that something didn't happen as expected in a dream, but not usually. These often don't result in my consciously realizing I'm dreaming--after all, things can be unexpected or not "seem right" in real life sometimes, too.
