a dream within a dream...

Today we watched Inception. I think this movie has a really cool idea, plus it has JGL and his smooth moves in it. But anyway, has anybody actually had a dream within a dream? Or had a dream where you know you're dreaming?

I think I have dreams where I know I'm dreaming a lot. Which is kind of fun sometimes because I can kind of control a little bit of what's going on in them. :) But sometimes I am dreaming, and I wake up from that dream, but I'm still in a dream...does that make sense? Not that I'm trying to uncover some sort of secret combination or anything fancy like that like in the movie, but it's still kind of interesting. Mostly I dream that I get some sort of pet, like a cute little baby puppy. :) But then as I start to wake up from that dream, the puppy disappears and I always think something like, "oh no, I'm dreaming again." And then I am mildly upset that the cute baby puppy isn't real. And then I was up from the puppy dream into some other random dream that I'm still having. Crazy, huh?

Does that happen to anybody else?
