I believe that during the night we are closest to God, especially when sleep won't come, or when we have dreams that trouble us and awaken us. I read somewhere that sleeping through for 8 hours is a fairly modern concept; that sleep used to be divided between the first and second sleep, (3-4 hours each) with a period of wakefulness in between. For years, my sleep has fallen into that pattern, and it's during that between time that I have my closest conversations with God and my deepest examination of conscience. God grants us that time of no distractions for us to spend time with Him. So I believe.
Last night I was thinking about how in my youth I had grand passions and longings that I thought I couldn't live without. Now I look back and am thankful that those were unanswered prayers, for they would have led me away from my faith.However circuitous the route, I think I am firmly planted where God wants me on my earthly journey, and I can finally let go of those dreams and desires. For if they take me away from God, I want no part of them.
