Ok, just a few minutes ago I found something out. I'll post the discussion I had with my brother over dinner.

[My mom]: "Oh Sean, I had the funniest dream last night!" (She proceeded to tell us what happened)

[My Brother]: "I like to mess up my dreams."

[Me]: "What do you mean, you like to mess up your dreams?"

[My Brother]: "I just punch people."

[Me]: "Do you know you are dreaming?"

[My Brother]: "Of course, what do think?"

[Me]: "No I mean not now, while you are dreaming."

[My Brother]: "Yeah... I'm sleeping and it just feels weird."

[Me]: "So you know you are dreaming, and you can do whatever you want?"

[My Brother]: "Yeah, why? What do you do?

I didn't answer him. I finished my dinner and came here as fast as I could to post this. I'm not a natural, and I had no idea he was a natural. Do you have any (surprise) lucid relations?
