Communicating with Krishna

How does one make decisions centred on the will of Krishna? Is it possible to interpret every choice that we are called upon to make at different stages of life wholly in light of the scriptures, primarily concerning the words and instructions of Krishna, such as the Srimad Bhagavatam and the Bhagavad Gita, and would a Krishna Conscious devotee consider it advisable to accept our dreams and visions of Krishna as being a reasonable and reliable authentic source of knowledge on which we could indeed base our decisions and choices instead of just seeing them as mere extensions of our imagination?
