Is this just puppy love, or is it real?

I'm 12, and there's a girl I like, she's friendly, beautiful, etc. Old story, right? but instead of having an innocent little desire many adults think people my age feel, I'm having ual desire for her , and I'm barely embarred or scared at all, every time I see her, I get extremely elated and happy. I also have another question. I can tell she likes me because, I happen to be the cl comedian in every cl I have, and she often thinks what I say is hilarious. i.e, when my math teacher got all pissed off and covered his face, I said "Geez, get the guy some aspirin already" and she laughs like hell. I also see her sometimes looking at me for a while and then looking away, and once I saw a small, yet beautiful smile on her face while looking at me. Early in the year, I thought of her as just a background girl in my cles, but then I had a dream where she took off her clothes and we did it, and then I all of a sudden fell for her. I want to tell her that I like her, but that's the one and only thing I'm nervous about. And if we do become friends, there's one major obstacle, my parents. If my parents know I have a girl, they'll tell all of the people in my family, who think I'm a baby, and they'll remark about how "adorable" it is, and when we get together, my parents will spy on us like we committed a crime. And I just don't like it when I'm trying to have a relationship when they are in TOTAL control of us, and that's what they're notorious for when it comes to other kids. Anybody?
