I did that once when I was little. I was on this game show and I won, and then reality just hit me in the face and I realised "Oh crap, I'm dreaming and I won't have this in the real world!" I went up to the game show host and I was like "Can you just give this to me when I wake up?" Funny thing is, I had a false awakening and when I was at school the gameshow host showed up to give me my prize. Then I woke up for real feeling like an idiot.
