What are possibilities of a regular believer to ask God any sort of questions in now

It may sound awkward, but if you'll allow me to explain, that would be great. Ok, there are some personal questions I wanna ask God, and these questions are about Astronomy, Space, life beyond Earth,my family history and so on, because what I'm looking for, I cannot find anywhere on Earth, and I want to ask the Al Knower about stuff like that because I'm really interested about it.

I have asked on Aboutislam.net and the scholar have said that if you have asked God a question and you had a dream, and then that dream keeps repeating itself all over again, then that means it is obvious the answer of God for my question.

What I want to know is: where it says like this in Quran just as that Muslim scholar has told me? So that I can officially believe in it.

What is the right way in which one can ask God personal question? I can ask God any question I want during the ritual prayers or during the supplication?
