st... of the coming changes, through your eye's and with your knowledge, would my survival be the most important factor in what actions i take?

can you explain why my sub conscience know's more about whats wrong with my life then my waking mind? and if so then why. i only ask this because whenever i interpret my dream they are filled with what mistakes i make in life..

do you dream, if you sleep? and do said dreams tell you anything about your life?
