Dream Predictions

Do you believe dreams are by random chance? Or can they tell you something in advance? I've had a few dreams that came true. Is this only me, or has it happened to you? A few weeks ago, I dreamt a that girl I like a lot got a diamond ring. Later I saw on facebook, she was engaged and planning her wedding. A while back in my sleep I saw a white car and one side was rammed in. My brother called that afternoon, saying someone ran a red light and hit him. I only bring it up because it happened again today. One of my good girl friends called and had something to say. She said I'm pregnant and want you to be the Godfather, will you? I said yes, then remembered last night I saw her with not one, but two. She went on to say, “I get the best of both worlds, its a boy and a girl.” “I'm having twins,” my head got light and the room started to swirl. I know I'm not Nostradamus, but there has to be an explanation. Or maybe I'm just going crazy and need a vacation. I hope I hear some similar things from you, and if not, I don't know what to do. I don't think I'm going crazy, my life is quite boring, and all the voices I hear in my head are usually just snoring.
