Disclosing one's past to the girl one is getting married to

Q: Suppose a boy has committed zina many at times with different girls. But now Allah has made this boy realise that it was very wrong and that boy has confessed for this to Allah and promised not to do it again. That boy is about to get married now. So should that boy disclose this fact to the girl he will be getting married that he has been physical with many girls or not? Because lying is also not allowed in Islam. Please guide me on this.

Dream

Q: I saw a dream that my family and I were going in a car and then there was a graveyard and dead bodies were kept against their graves to be buried. The   graves were open. I saw them and thought I will also be there one day and then I got up. Does these types of dream means a person is going to die or what? I am in a constant state of anxiety after seeing these types of dreams.

Consulting one's parents with regards to nikaah

Q: I have got to know a boy from my town and we both have fallen for each other. I performed salaahtul istikhara and my dreams where positive. However his parents do not approve of me. I have been modern but I try hard to live my life Islamically. He has performed istikhara salaah as well but didn't have any dreams. We really want to make our relationship halaal. What should we do?

Dream

Q: My aunt passed away recently and I saw her in a dream. I can't remember too much of what happened but I remember that it had something to do with her and perfume. Either she was requesting perfume or someone was giving her perfume it was definitely one of the two. Could you please tell me what it means?
