your dreams are manifestations of your subconcious, or maybe even projections thereof, but as fart as analasys while in dreams, you can communicate with your subconcsious to a degree through a dream guide or character, but if you are keeping something secret, you probabyl wont be able to bring it out in your dream, i mean, you already know yourself, what are you hoping to learn? i dont know if you can bring repressed memories to light in dreams, sometimes you might dream of a horrible incident in your life, but not on purpose.......your dreams can bring up the most annoying and sometimes painful things when you least expect it......
