Don't know what to do?

Last night I had a dream, that to me seemed so real.  I've had dreams like this before, but they never seemed real to me like this one did?  Is there anyway to interpret what your dreams really mean or could mean?  I hope this dream doesn't come true, or hasn't already?!  What to do?  Sometimes I just wish I could turn my brain off and then maybe I wouldn't dream at all!!lol  Would make life so much easier!
