What Do Your Dreams Really Mean?

You hear in the Bible about one of God's men interpreting dreams. There are psychologists who think that just because they know human behavior, they can interpret dreams. But what do your dreams truly mean? Dreams range based on emotions. You can dream of funny things, sadness, anger, horrible accidents, perverted truths and desires. Yet, what do they mean? Are they your subconscious coming to the forefront when your conscious mind is resting? Are they things you want to say, think, or feel in real life, but you are unable to do so. or is it all just like a computer, taking most visited memories or places and perverting them to make you doubt yourself and your reality. I have had many a dream where I woke up thinking that it had really occurred, or I felt like I had in the dream. I find myself having dreams about a friend I was holding a grudge against, but in the dream, we were best friends again, I awoke to find myself thinking about how that friend and I had had the best of times yesterday, when we didn't even talk yesterday! The dream left lingering memories and feelings that never occurred. Does this mean something? Why do our dreams constantly remind us of reality? What are dreams??
