Guys, how can a very shy girl approach a guy?

Ok, so I'll try to make this as short and sweet as possible. I fancy this guy but I'm a really shy girl who rarely is the first one to start up a conversation or call anyone apart from when someone first speaks to me. I can't tell you how much I really hate this about myself. I'm so shy and awkward... some nights I dream about talking to him and then I wake up, wishing it was real. But if I become bold and make a move, everyone will think it's out of character for me and be like "whoa, what happened to this quiet girl?"
I don't know how to approach him. Any suggestions would be greatly appreciated. Thanks for taking the time to read this and sorry if I rambled on a bit. ☺
