I dreamt that I was not dreaming!

In my dreams I either have no idea that I am dreaming and that thought doesn't even cross my mind. Or I know perfectly well that I am dreaming (usually I figure that out when a dream involves something that should invoke physical pain and I feel nothing, or something should invoke an emotion and I feel nothing.)

But this dream completely startled me as it started with me sitting in a truck and for whatever reason immediately realized I was dreaming. Ok all is well, but then as I start the truck up and start driving this incredibly wonderful feeling passed through as if to my very soul and I realized I was not dreaming!

I don't think I ever felt so wonderful! But then, the alarm clock woke me up

Well, that is it, hope I explained myself, twas rather an odd one. Anyone else dreamt that they were not dreaming?
