Has anyone ever realize they were dreaming and just wake up?

I've grown out of it now, but I used to have out of body experiences while I was sleeping. It's usually called sleep paralysis. I would TRY to wake up, realizing I was dreaming, and then I would realize I was still in my bed and could not wake up. Then I would DREAM I was awake, and try to get out of bed, but would end up right back in bed.
