if you truly seen Prophet Muhammad (PBUH) in your dreams indeed Allah has honored you to see his great creation. your eyes and heart are now worthy to the Prophet Muhammad, i heard an hadith Prophet will not allow you enter hell and he will be your intercessor on the day of qiyamah he will protect you because you are his no matter what you are he loves you. this does not mean you sin openly but to take shahadah daily as you witnessed him, this is his mercy for you so you should believe in him and Allah swt now and worship Allah SWT and be consistent on making tauba every day. do more righteous work everyday read the Quran, spend on charity etc. may Allah allow others to see our Beloved Prophet Muhammad. ameen.
