If I want any information to be revealed to me in a dream,how do I influence it or get the right information that I need.

Ask yourself before going to sleep every night. Ask for answers that you seek or looking for. Even do this during the day. Have the mindset that you have questions and that you are looking for answers and you want to open your dreams to them.

I am not sure of your beliefs but praying about revealing answers to you and you will start to get your answers.

I have no idea
But you could always check dreammoods.com, don't know how accurate it is, but who really knows

Yes, praying helps a lot, well... if you know to whom you are praying too, and also you have to believe that what you ask for will come to past ;)
