My ex had a dream about me...what should i do?

my ex and i broke up because my parents didnt want us together( he has a rough past but i loved him anyway) and we remained friends since we broke up late 2007. we lost touch a few months, then started messaging every once in a while. it became weird because we started thinking about trying to get together again in the future when we could, but we were technically only friends. then pet names came up again. and the feelings i never fully got over came back. i tried backing off and he messaged one day out of the blue to tell me he had a dream about me and had to tell me what happened. this is a very condensed version. so he said there was a child walking holding a bomb and they found a hole to put it into and seemed relieved but they fell and the bomb exploded. somehow he and i escaped but everyone around us eventually died as a result of the explosion...debris falling and such. he lost everyone and woke up (as he said) thinking he couldnt lose me. he proceeded to tell me he was still sweating and it was weird for him because it bothered him and he is a pretty hard person. trust me on that, he is. it also was different for him because he saw me in particular. of course i asked if he was ok, we had a converstaion about it, and he said he thinks we should be together again no matter what anyone says. i told him i'd like that, but we couldn't right now, and i want to do things the right way, such as getting married before living together. and finishing college before marriage...i have 2 years left. now the next part caught me off guard. my ex wasn't the type to settle down and get married. he never saw himself getting married. i found out after we broke up. but then, sounding somewhat desperate, or maybe saying what i wanted to hear or maybe being genuine, he asked if i would marry him... i questioned him about it and he convinced me he was serious. but he still wanted to wait until i wasnt living with my parents so it wouldnt be an issue. we've started talking nearly every day now, but through ims and emails, because it has to be a secret from my parents... i've been so confused... please help
