You might be eligible to have your husband petition for you and gain resident status through him. If you have ever left and re-entered on advance parole under your DACA status (technically, you have deferred action, not the Dream Act, but I do know what you mean). or if someone has ever petitioned for you or one of your parents before May 1, 2001, you might be eligible to adjust your status in the U.S. without having to leave at all. Otherwise, you might qualify to consular process with a Provisional Waiver, in which you would be able to stay here while the waiver is adjudicated but would then need to leave for approximately 2-3 weeks for a visa interview outside the U.S.
I recommend meeting with an attorney to review your specific case and options. Best of luck!
If you are married to a U.S. citizen, your spouse can file a petition for you on Form I-130. I recommend finding a good immigration lawyer in your area to help. Because you received Deferred Action, you may be able to get Advance Parole. If that's the case, then you may be able to get your green card in the United States without needing a waiver. This gets complicated and confusing very quickly, so best to work with an attorney. Good luck.
in addition to other advises you received, your attorney needs to know how you entered the country, and if you entered with a visa then your husband can assist you in filing your adjustment here, but if you entered illegally you must either apply for your green card after your husband petitions for you from your home country or since you are granted DACA, then you must apply and be granted an advance parole first, make a trip and come back to the U.S., and then apply for adjustment while in the U.S.
having a consultation with an experienced attorney will serve you well.
