What does my dream mean?

ok so all week i have been having dreams that i am with my boyfriend and he comes to my door during the day and my mom doesnt care. but im not supposed to have a boyfriend. also in some of these dreams he comes to bar-b-ques with the whole family and my dad doesnt care either. these dreams make me feel happy because im with him and i have seen him since like june 1st. my sister even told me that when she walks in my room at night im smiling. does this mean i should tell my parents and they wont be mad? why do i keep having these dreams?
