If the Department of State issued you an American passport, you are an American citizen. Even if your US passport expired, you are still an American citizen. Based on the law in 2000, if you had a green card and your parents naturalized before your turned 18, you automatically became an American citizen. Your became an American citizen on that same day your parents naturalized, even before your US passport was processed. You are a "Ghost" because you probably never filed for a certificate of Citizenship. This is in my opinion an unnecessary step, something to make you spend money in USCIS filing fee. The INS / USCIS never got "Official confirmation" that your became a citizen because you never filed the N-600, application for certificate of citizenship. Do not worry. You are OK. Just make sure to renew your US passport when it is about to expire.
