Have you ever done a reality check and been genuinely surprised that you were awake?

It happened to me the other night. I woke up and my body felt tingly and "distant." I looked at the digital clock and it was blurry. I looked back again and it was still blurry (I don't wear glasses). I actually got that internal rush that happens when I realize I'm dreaming, but when I did the nose RC, it confirmed that I was awake. I was shocked.
