The dream in which you were lost, means that in real life at you many questions ripened and you lost former confidence. If in a dream you got lost and cannot find the required building, then in life you are overcome by thirst of adventures. If you lost a reference point in the building, then in reality you should rely on an intuition more. If dreamed you that you try to come to the lost footpath, then in reality you risk to fail in well planned business.
Be sure and keep any other thoughts out of your mind before drifting to sleep as a cluttered mind can decrease the chances that you will remember your dreams upon waking. Also, focusing on remembering your dreams upon waking in the morning is another very important thing. This sounds very easy, but is often hard for some to do.
