I have lucid dreams, there are tricks you can do to encourage them: 1) Keep a dream journal, 2) every night before you go to sleep, tell yourself that you will remeber your dreams and you will know when you are dreaming, 3) Clear your mind before you sleep, 4) During your waking day, every now and again ask yourself "am I dreaming?". If you get in to the habit of doing this, you will do it in your sleep.

jeffhx - when you dream about a house, generally its a dream about yourself, the different rooms and people in it being different aspects of your life. For instance, the dirty walls may represent something in your life that is being neglected.

elklandercc - Sometimes, in our dreams we meet up with people. Some that we know in real life, some we don't. So if you fall in love in a dream, its possible that some girl somewhere in the world is having the same dream about you!!

Umm, I know alot more about dreaming and paranormal things than I do about guitar.
